AB  - In parallel with the plethora of biomedical applications that employ atmospheric pressure plasma systems, another field of plasma applications is growing – plasma agriculture [1]. Chemical species in plasma, with ample amounts of Reactive Oxygen and Nitrogen Species (RONS), are responsible for triggering various mechanisms and effects in plant cells. For example in treatment of seeds, the rich plasma chemistry changes the coat of the treated seed resulting in changes of wettability, better water uptake, an increased percentage and speed of germination [1-3]. Another application of atmospheric pressure plasmas is for treatments of plant calli In biological research and biotechnology the plant callus (pl. calli) is induced from plant tissue and it forms growing mass of plant meristematic cells. Plant callus is widely used in plant biology both for basic research and industrial production: in plant biotechnology
as a tool for genetic manipulation of plants, for micropropagation, for studies of plant metabolism and cellular development, commercial production of natural products that cannot be chemically synthesized etc.. Puač et al. have studied the influence of RONS on Daucus carota calli showing their long-term influence [4]. We have used plasma needle type of the atmospheric pressure plasma device for direct plasmas treatments of
plant calli. The operational frequency of the device was 13.56 MHz and working gas was helium. The flow of
helium was kept constant at 1 slm  The detailed characterization of the discharge was performed by optical emission
spectroscopy, mass spectroscopy and electrical measurements  The direct plasma treatment of the plant calli was
used to investigate the plasma-cell interactions and to follow the response of the plant tissue several hours and days
after the treatment  We have used calli of model plant (Daucus carota) and of plants with specific issues, like small
bearded irise (Iris reichenbachii) who mainly produce non regenerative calli that do not enter the process of somatic
embryogenesis (SE)  Firstly, in treatments of D.carota calli we found that the formation of SE can be initiated even
under non- permissive conditions. Similar effects were obtained with I. reichenbachii calli where the atmospheric
plasma treatment induced significant morphological and physiological changes in non-embryonic calli toward SE
formation that were followed also with the enhanced production of arabinogalactan proteins

AB  - Over the last years, cytokinin deficiency has been studied in a variety of plant species, using transgenic expression of cytokinin oxidase/dehydrogenase genes (CKX). In tobacco and Arabidopsis thaliana, overexpression of A. thaliana CKX genes caused changes in plant morphology known as the "cytokinin deficiency syndrome", including stunted shoot growth, decreased apical dominance, and enhanced root growth. For a valid comparison with the previously obtained in vitro grown AtCKX2-transgenic potato lines, we report here on the construction of transgenic lines of the cultivar Désirée constitutively expressing the gene AtCKX1 under control of the CaMV 35S promoter. Three lines expressing the transgene in both shoot and root tissues were used for analysis. Analyses of CKX activity of tissue extracts, cytokinin levels, morphology, and tuberization parameters revealed similarities as well as differences from the AtCKX2-transgenic plants, including lower levels of CKX activity, and more pronounced morphological effects of cytokinin deficiency. One of the three AtCKX1-overexpressing potato lines was able to start forming tubers before 30 days of growth in long day conditions (16 h/8 h photoperiod) as has been previously observed in some AtCKX2 overexpressors. The extension of the experimental period to 120 days of growth in vitro showed that the other two AtCKX1-overexpressing lines showed impaired tuberization in terms of the number of tubers per plant, and tuber size. We conclude that cytokinin deficiency has distinct effects on tuber induction and tuber initiation/growth, possibly mediated by distinct signaling mechanisms.

AB  - Gentianaceae have a long history of use as traditional remedies for treatment of various ailments. The medicinal properties of crude herbal drug are attributed to bitter glycosides, flavonoids, and xanthones, the main plant secondary metabolites. These plant-derived molecules, especially naturally occurring xanthones, possess a broad spectrum of bioactivity like anticarcinogenic, antimicrobial, neuroprotective, antidiabetic, cardio-protective. The most of Gentianaceae species are rare and endangered by uncontrolled overharvesting and influences of various environmental factors (habitat loss, climate change, and invasive species spreading). Decline of Gentianaceae species poses a high risk to the loss of enormous diversity of potentially bioactive compounds. In this chapter we will summarize pharmacological activities of identified secondary metabolites from endangered species belonging to four Gentianaceae genera (Gentiana, Gentianella, Centaurium, Swertia), as well as importance of biodiversity conservation in context of their biotherapeutic potential.

AB  - The development of "green" alternatives to chemical pesticides could play a crucial role in integrated pest management (IPM). Their use is considered either as a substitution for or in addition to hazardous synthetic products. We analysed the influence of three concentrations of tansy (Tanacetum vulgare L.) essential oil (EO), previously characterised by GC-MS, on the survival and moulting of the 2nd instar and the nutritional indices of the 4th instar gypsy moth (Lymantria dispar L.) larvae. In a residual contact toxicity assessment, the exposure to tansy EO caused low mortality (< 10%) while larval development was significantly slowed down, i.e., the percentage of larvae that moulted into the 3rd instar was reduced. On the other hand, when tansy EO was incorporated into the diet (digestive toxicity assay), high mortality and a lack of moulting after 120 h of eating were recorded for the highest applied concentration of EO. During 48 h of feeding on EO-supplemented food at concentrations of 0.5 and 1% (v/v), the relative growth rate (RGR) of the 4th instar larvae significantly decreased, which can be explained by a significant reduction of the relative consumption rate (RCR) and significantly or marginally significantly lower efficiency of conversion of ingested food into insect biomass (ECI). Although the RCR was also reduced with the lowest applied EO concentration (0.1%), the ECI was not affected which meant the RGR was as high as it was for the control larvae. ECI changes, when two higher EO concentrations were applied, were due to a reduction in the efficiency of conversion of digested food into biomass (ECD), while approximate digestibility was unaffected by the presence of EO in the food. Our results on the significant negative effects of tansy EO on gypsy moth larval survival, development time, and nutritional physiology suggest that it could be considered in future designs for botanical insecticides for gypsy moth control.

AB  - Glandular trichomes found on the surface of many higher plants contain specialized cells that produce and secrete copious amounts of particular secretory products. Leaf glandular trichomes of the non-model plant species Nicotiana tabacum represent a biologically active and stress-responsive tissue that contributes to plant defense response against biotic and abiotic stress and also influences leaf aroma and smoke flavor. Two morphologically different types of tobacco capitate trichomes, long- and short-stalked, with distinct functions, display ultrastructural features that are common to terpene-secreting glands, but only the secretory cells of the tall glandular trichomes are considered to be the site of biosynthesis of certain exudate compounds, including diterpenes and sucrose esters. Ultrastructural and histochemical characterization of tall glandular trichomes is described in an attempt to understand the contribution of these glands to the total secretion produced. Possible roles of distinct cellular compartments involved in the secretory process and secondary metabolite secretion under in vitro conditions are discussed.

AB  - Cauliflower is exposed to various biotic and abiotic stresses, including increased salinity due to the intensive irrigation of crops. Mitogen-activated protein kinase (MAPK) cascades are universal signal transduction modules that play important roles in regulating innate immune responses in plants. Based on involvement of tobacco MAP kinase kinase kinase (NPK1) in stress response, the effect of the expression of NPK1 transgene to NaCl salt stress tolerance in cauliflower KFRM4 lines was studied. The Agrobacterium tumefaciens-mediated transformation protocol, using EHA101(pSHX004) vector harbouring the NPK1 and phosphinothricin N-acetyltransferase (bar) genes, the cyclic somatic embryogenesis regeneration pathway, the application of acetosyringone (AS) during co-cultivation and a delayed phosphinothricine (PPT) selection procedure provided sufficient transformation efficiency of 7.33% without escapes. PCR analysis indicated the integration of both NPK1 and bar transgenes in regenerated cauliflower lines. Transgenic cauliflower lines, exposed to NaCl stress in vitro, showed higher growth rates, greater ability to retain chlorophyll and carotenoids, and increased osmotic regulation capacity compared with non-transformed control plants. The tolerance level of transformed lines correlated with the level of NPK1 gene expression estimated by RT-qPCR, and the L2 line with the highest NPK1 expression displayed the greatest tolerance to NaCl stress. None of the obtained cauliflower transformed lines grown in greenhouses showed any morphological or yield differences compared with non-transformed plants. Furthermore, the expression of the bar gene facilitated the tolerance of transformed lines to the total herbicide PPT, applied at concentrations 2-3 times higher than those routinely used for weed control in the crop field. Key message The results underlined that constitutively expressing NPK1 can significantly contribute to enhanced salt stresstolerance in cauliflower, suggesting that this could be a promising basis for the creation of new stress tolerancecruciferous vegetable lines.

AB  - Gibberellins (GAs) play a pivotal role in the induction of somatic embryogenesis from in vitro root apices of spinach plants. With the aim to understand the role of GAs in this process and to improve somatic embryo (SE) regeneration efficiency, the impact of light and GAs on SE initiation from the in vitro root apices was studied. The root sections were isolated from in vitro-grown SE-derived plants and placed on medium containing 20 µM α-naphthaleneacetic acid (NAA) and 0–10 µM GA3 or GA1, and cultivated under light conditions or in darkness. The most efficient SE regeneration response (100% regenerating SEs and 40.73 SEs per root apices) was achieved only in the presence of both light and GAs, with GA3 always exhibiting much stronger effect than GA1. Considering that light enhances GAs biosynthesis and the necessity of GAs for SE initiation, the expression levels of genes encoding the key enzymes involved in the final steps of GAs synthesis (SoGA20-ox1 and SoGA3-ox1) and deactivation (SoGA2-ox1, SoGA2-ox2 and SoGA2-ox3) were analyzed. Light enhanced the expression of all five GA-ox genes, while exogenously supplied NAA + GA3 provoked downregulation of SoGA20-ox1 and SoGA3-ox1 and upregulation of SoGA2ox-2 and SoGA2ox-3 expression. The expression of SoGA2ox-1 only slightly decreased. The results indicated the capability of isolated spinach roots to perceive the light and autonomously produce GAs. The expression levels of genes encoding key enzymes involved in GA biosynthesis suggest that lower levels of GAs favor SE initiation.

AB  - Taking advantage of advanced high performance liquid chromatography–electrospray tandem–mass spectrometry (HPLC–ESI–MS/MS), we screened daily changes in concentrations of endogenous phytohormones of in vitro grown potato (Solanum tuberosum L. cv. Désirée) shoot cultures and checked for possible connections between the rhythmicity of endogenous phytohormones and phototropic bending capacity of the same cultures. Studies done under diurnal 16 h light and 8 h darkness (diurnal) and continuous light (CL) conditions showed prominent daily rhythmicity of endogenous phytohormone levels in both light regimes. Phototropic bending in potato is known to be rhythmic only in the diurnal, whereas in CL conditions the bending response is present but without any daily rhythmicity. For all of the studied phytohormone groups significant differences between the diurnal and CL conditions were found. Changes in the concentration of indole auxins, indole-3-acetic acid (IAA) and its catabolite 2-oxindole-3-acetic acid (OxIAA), were the most prominent. Their levels clearly alternated with level of IAA being high in diurnal and OxIAA in CL conditions. Significant concentration changes were also observed for other phytohormones such as cytokinin ribosides, salicylic acid, abscisic acid and phaseic acid. Observed changes in daily phytohormone levels indicate strong and complex involvement of diverse phytohormone groups in realization of the phototropic bending response of potato shoots.

AB  - A number of scientific reports published to date contain data on endogenous levels of various phytohormones in potato (Solanum tuberosum L.) but a complete cytokinin profile of potato tissues, that would include data on all particular molecular forms of cytokinin, has still been missing. In this work, endogenous levels of all analytically detectable isoprenoid cytokinins, as well as the auxin indole-3-acetic acid (IAA), and abscisic acid (ABA) have been determined in shoots and roots of 30 day old in vitro grown potato (cv. Désirée). The results presented here are generally similar to other data reported for in vitro grown potato plants, whereas greenhouse-grown plants typically contain lower levels of ABA, possibly indicating that in vitro grown potato is exposed to chronic stress. Cytokinin N-glucosides, particularly N7-glucosides, are the dominant cytokinin forms in both shoots and roots of potato, whereas nucleobases, as the bioactive forms of cytokinins, comprise a low proportion of cytokinin levels in tissues of potato. Differences in phytohormone composition between shoots and roots of potato suggest specific patterns of transport and/or differences in tissue-specific metabolism of plant hormones. These results represent a contribution to understanding the hormonomics of potato, a crop species of extraordinary economic importance.

AB  - We present changes in Tacitus bellus antioxidative system that specifically correspond to subsequent phases of hemibiotroph Fusarium verticillioides infection revealed by histological analysis. T. bellus response to spore germination 6 h post inoculation (hpi), manifested as first oxidative burst, was characterized by transient decrease in malondialdehyde (MDA) content, transient increase in catalase (CAT), low level of superoxide dismutase (SOD) and peroxidase (POD) activity, as well as with transient decrease in total antioxidant capacity (TAC), total phenol content (TPC) and phenylalanine ammonium lyase activity (PAL), and no changes in polyphenol oxidase (PPO) activity, or phenolic profile. During the biotrophic phase of F. verticillioides infection, characterized by hyphae spread intercellularly in epidermal and mesophyll tissue, the host antioxidative system was suppressed. The transition to necrotrophic phase of F. verticillioides infection (inter- and intracellular colonization and sporulation), occurred 3-4 days post inoculation (dpi). During the necrotrophic phase, 5-7 dpi, slowed progression of colonization of T. bellus mesophyll cells occurred and it coincided with sharp increase in MDA content and CAT, SOD and POD activities, but the drop in TAC, TPC content, and PPO activity, as well as the production of phytotoxin fusaric acid. Presented results add to the knowledge of events and mechanisms related to the transition from biotrophy to necrotrophy in F. verticillioides.

AB  - Active ingredient of the commercial herbicide BASTA (B), phosphinothricin, acts as an inhibitor of glutamine synthetase (GS), a key enzyme in ammonium assimilation. The treatment with BASTA leads to an elevation of ammonium levels in plants and further to various physiological alterations, ammonium toxicity and lethality. Results of the present study emphasize the complexity underlying control mechanisms that determine BASTA interaction with essential oil (EO) from Nepeta rtanjensis (NrEO), bioherbicide inducing oxidative stress in target plants. Simultaneous application of NrEO and BASTA, two agents showing differential mode of action, suspends BASTA-induced ammonium toxicity in Arabidopsis thaliana plants. This is achieved through maintaining GS activity, which sustains a sub-toxic and/or sub-lethal ammonium concentration in tissues. As revealed by the present study, regulation of GS activity, as influenced by BASTA and NrEO, occurs at transcriptional, posttranscriptional, and/or posttranslational levels. Two genes encoding cytosolic GS, GLN1;1 and GLN1;3, are highlighted as the main isozymes in Arabidopsis shoots contributing to NrEO-induced overcoming of BASTA-generated ammonium toxicity. The effects of NrEO might be ascribed to its major component nepetalactone, but the contribution of minor EO components should not be neglected. Although of fundamental significance, the results of the present study suggest possible low efficiency of BASTA in plantations of medicinal/aromatic plants such as Nepeta species. Furthermore, these results highlight the possibility of using NrEO as a bioherbicide in BASTA-treated crop fields to mitigate the effect of BASTA residues in contaminated soils.

AB  - Kohlrabi (Brassica oleracea var. gongylodes) is an important vegetable crop that is able to undergo shoot regeneration in culture from intact seedlings in a single-step regeneration process, using cytokinin as the only plant growth regulator. In this work, we present the expression profiles of seven organogenesis-related genes over the time course of shoot regeneration from intact seedlings of kohlrabi cv. Vienna Purple on shoot regeneration media containing trans-zeatin, cis-zeatin, benzyl adenine or thidiazuron. Two auxin transporter genes - PIN3 and PIN4, a cytokinin response regulator - ARR5, two shoot apical meristem-related transcription factors - CUC1 and RGD3, and two cell cycle-related genes - CDKB2;1 and CYCB2;4 - displayed bimodal expression patterns on most cytokinin-containing media when their expression levels were normalized against control plants grown on hormone-free media. The first expression peak corresponded to direct upregulation by cytokinin from the growth media, and the second one reflected transcriptional events related to callus formation and/or acquisition of organogenic competence, corresponding to the shoot regeneration phases that have already been characterized in Arabidopsis thaliana. We demonstrate that the genes involved in the two-step shoot regeneration of Arabidopsis display their expected expression profiles during the single-step shoot regeneration of its close phylogenetic relative kohlrabi confirming the universality of their roles in the distinct phases of the regeneration process in Brassicaceae. The results presented here represent a first step towards genetic characterization of the morphogenetic processes in this important crop species.

AB  - Cross–talk between phytohormones and sugars was earlier shown to be involved in higher plants regeneration. While our previous work revealed that phytohormones metabolism may be triggered by sucrose signalling in de novo shoot organogenesis (DNSO) of kohlrabi (Brassica oleracea var. gongylodes), the effect of sucrose on callus formation and shoot regeneration remains unknown in this important crop. Present study was intended to estimate if successful DNSO, occurring from intact kohlrabi seedlings due to influence of exogenous cytokinins (CKs) - trans zeatin (transZ) and thidiazuron (TDZ) and high sucrose concentration (6 and 9%), was accompanied by distinctive alterations in expression levels of organogenesis-related genes. The relative activity of genes involved in auxin transport, CK response, de novo shoot apical meristem formation and cell division - PIN3, ARR5, RGD3, CDKB2;1 and CYC2;4, was determined by quantitative PCR analysis showing variation in expression levels during callus formation (CF) and de novo shoots regeneration (SR). Generally, expression was downregulated with TDZ being more effective, especially when higher amount of sugar was applied. Exception was ARR5, mainly upregulated with transZ that had greater impact than in other analysed genes. We also examined correlations between total CK content and distinct gene expression depending on the treatment. Our results demonstrated predominantly negative correlations, apart from all TDZ treatments in CF and TDZ and transZ with 9% sucrose in SR, indicating complex regulatory network underlying kohlrabi DNSO.

AB  - Potato fields pest protection is still predominantly based on synthetic pesticides, expensive in terms of monetary investment and proved to be harmful to human health and the environment. Alternatively, flower strips of French marigold (Tagetes patula L.) appearing as potent pest repellents in potato fields, offer well-adopted practice in organic farming. Up to now, the effect of French marigoldon potato metabolism, physiology, and yield has not been studied in detail. Thus, a microarray transcriptome analysis was performed to study the effect of French marigold essential oil (EO) on laboratory-grown potato, with the focus on starch metabolism pathway. After 8h of exposure to EO, 3840 potato probes were differentially expressed (fold change ≥2) compared to control plants, of which 1744 were upregulated and 2096 downregulated. We selected a set of putative genes involved in the starch metabolism pathway in plastids, and validated microarray patterns using RT-qPCR method. The expression of selected genes was analyzed in plants exposed to EO for 4, 8 and 12h . While the expression of genes involved in starch biosynthesis was at similar levels as in non-treated plants, the most of the genes responsible for gradual degradation of starch displayed significantly elevated expression with the highest levels detected after 8 and 12h of exposure. Our results provide a comprehensive sequence resource for studying the potato-EO interactions, revealing induced alternations in potato starch metabolism and suggesting modified regulatory mechanism in potato affected by EO.

AB  - Methanol and aqueous extracts of French marigold flowers and leaves, with previously determined chemical profiles, were subjected to in vitro antioxidant and antimicrobial assays. The methanol extract of flowers had the highest total phenolic content (TPC) according to the Folin–Ciocalteu method, and UHPLC–LTQ/orbitrap/MS analysis identified the flavonoid aglycones as the dominant class of phenolics in the extract. Likewise, the methanol extract of flowers showed the highest antioxidant activity measured by DPPH and ABTS assays. Generally, the higher TPC correlated with lower IC50 value and stronger antioxidant potential in all extracts. Microdilution test was used for determination of the minimum inhibitory (MIC) and minimum fungicidal (MFC) concentrations of French marigold extracts on following microfungi - Aspergillus versicolor, A. niger, Penicillium ochrochloron, P. verrucosum var. cyclopium and Alternaria alternata. The antimicrobial test revealed that P. ochrochloron was the most sensitive while A. niger was the most resistant microfungus to all analyzed extracts. Correspondingly, the methanol extract of flowers was shown to be the most potent one, regarding the antimicrobial activity. Additionally, antimicrobial potential of methanol extract of flowers was tested for in vivo potato tuber protection against A. alternata causing the early blight disease. Based on obtained antioxidant and antimicrobial potential, French marigold methanol extracts could provide an alternative strategy for the controlling expansion of potato pathogens.

AB  - Species of the genus Aesculus are among the most attractive ornamental woody plants. Conventional propagation methods of these species are either inefficient (stem cuttings) or unsuitable for clonal propagation (seeds). The aim of the present study was to develop an efficient protocol for clonal propagation of elite specimens of yellow buckeye (Aesculus flava) by somatic embryogenesis. For this purpose, stamen filaments of yellow buckeye were cultivated on media supplemented with 1, 5 or 10 μM 2,4-dichlorophenoxyacetic acid (2,4-D) combined with 0, 1, 5 or 10 μM 6-furfurylaminopurine (Kin), either under light or dark conditions, for 8 weeks, and then subcultivated on plant growth regulator (PGR)-free medium with 400 mg/l of glutamine. The highest somatic embryo (SE) initiation rates were achieved for the explants cultivated in darkness on medium containing 1 μM 2,4-D + 10 μM Kin during callus induction (CI) phase. Embryogenic calli (EC) were initiated from friable calli, starting from the 7th week of culture initiation, while SEs appeared two weeks later, following a week of subcultivation of the explants on PGR-free medium. EC and SEs were observed only in the explants grown in darkness during CI phase. Minimal duration of CI phase and darkness necessary for SE induction was four weeks, while the highest embryogenic response was achieved when each lasted for 8–10 weeks. Obtained SEs were efficiently multiplied on medium supplemented with 0.05 μM 2,4-D + 5 μM Kin by recurrent somatic embryogenesis. SEs at globular stage of development exhibited the highest capacity for secondary SE regeneration. High germination and conversion rates were attained in cotyledonary-stage SEs cultivated on medium with 0.05 μM 2,4-D + 5 μM Kin, but this phase needs to be further optimised, since the obtained plants failed to acclimatize to greenhouse conditions. During the transition of calli from friable to embryogenic state, total peroxidase (POX) activity significantly decreased, indicating their involvement in the acquisition of embryogenic capacity. The presented protocol is suitable for clonal propagation and genetic transformation of this ornamental species, and POX activity may be used as a marker for SE initiation.

AB  - The investigation of allelopathic potential and mode of action of the main apple root secondary metabolites, phloridzin and phloretin is difficult to perform due to high complexity of rhizosphere interactions. Therefore, the generation of in vitro hairy root cultures could be an alternative system for allelopathic studies of apple. The efficient induction of hairy roots in apple cvs. Melrose, Golden Delicious, Ĉadel and Gloster was obtained using the appropriate mode of inoculation of regenerated shoots by Agrobacterium rhizogenes 15834. Permanent in vitro culture of apple autonomous hairy roots was established for the first time by cultivation on alternating growth media with and without auxins. UHPLC(+/-)HESI-MS/MS analysis confirmed that genetic transformation did not lead to changes in the content of the main secondary metabolites of apple roots. Dihydrochalcones phloridzin and phloretin, chlorogenic and caffeic acids were detected as only putative allelochemicals exuded into the growth medium in which hairy roots were grown. Apple hairy root exudates significantly affected development and growth of Arabidopsis thaliana seedlings. Pure phloridzin at 500 μM and phloretin in all tested concentrations (125-500 μM) had similar effects as apple hairy root exudates inducing significant alterations in morphology of seedlings, expecially roots. High similarities in the expression patterns of genes involved in polar auxin transport and auxin and gibberellin biosynthetic pathways in roots of arabidopsis seedlings treated with either apple hairy root exudates or 500 μM phloretin were observed. This indicates that phloretin in hairy root exudates could be at least partly responsible for the apple root allelopathic properties, that were most likely based on auxin and gibberellin cross-talk and their altered homeostasis in arabidopsis roots.

AB  - Inter- and intrapopulation variability in six natural populations of the rare species Gentiana pneumonanthe was examined based on morphological and chemical data. Population size and linear morphometric parameters differed significantly among populations, but without a clear connection to habitat conditions, i. e. water supply and light availability. Leaf shape varied from ovate to lanceolate in all populations, and one population was distinctive in having the largest number of leaves of transitional shape. HPLC analyses of six secondary metabolites were performed separately for belowground parts, and aboveground vegetative and reproductive parts of individual plants (6 populations ×7 individuals ×3 plant parts, n=126) in order to examine differences at the population and individual levels. Three secoiridoids (swertiamarin (SWM), sweroside (SWZ), and gentiopicrin (GP)), one xanthone (mangiferin (MGF)), and two flavones (isoorientin (IO) and isovitexin (IV)) were detected and quantified in the analyzed samples: sweroside dominated in the aboveground reproductive part, mangiferin in the aboveground vegetative part, and gentiopicrin in the belowground part. At the population level, differences in contents of the analyzed chemicals among populations were significant only for a few metabolites. At the individual level, a pronounced organ-dependent distribution of secondary metabolites was revealed. The results of this study contribute to a better understanding of natural variability within populations of the rare and threatened G. pneumonanthe, and provide data on the contents and within-plant distribution of secondary metabolites, which are important as pharmacologically active compounds and may be useful for further biotechnological procedures regarding this species.

AB  - Allelopathic plants exploit their chemical ‘weapons’ to prevail over the competition, suppress neighboring plants and consequently
use the available resources more efficiently. However, the investigation of plant allelopathic interactions in rhizosphere is difficult
to perform because of its high complexity due to interactions of biotic and abiotic factors. Thus, autonomous, aseptic root cultures
of apple (Malus × domestica Borkh.) could facilitate allelopathic studies. We report on the successful genetic transformation of
apple cultivars Melrose, Golden Delicious, Cadel and Gloster using ˇ Agrobacterium rhizogenes (Riker et al. 1930) Conn 1942 strain
15834 and for the first time the establishment of apple autonomous and permanent in vitro hairy root cultures that could be used
as a new tool for apple allelopathic assays. Molecular characterization of transgenic hairy root lines was conducted to elucidate
the possible relationship between expression of T-DNA genes and root growth characteristics that include branching. Similar content of phenolic acids (chlorogenic, caffeic, syringic, p-coumaric and ferulic), glycosilated flavonoids (rutin, quercitrin, isoquercitrin,
kaempferol-3-glucoside) and flavonoid aglycones (quercetin and naringenin), and dihydrochalcone phloridzin, was detected in
untransformed and transgenic apple root tissue by ultra high-performance liquid chromatography with mass spectrometry
(UHPLC/(+/–)HESI–MS/MS) analyses, confirming that genetic transformation did not disturb secondary metabolite production in
apple. Chlorogenic and caffeic acids and dihydrochalcones phloridzin and phloretin were detected as putative allelochemicals
exuded into the growth medium in which transgenic roots were maintained for 4 weeks. Apple hairy root exudates significantly
affected shoot and root development and growth of test plant Arabidopsis thaliana (L.) Heynh. seedlings after 5 or 10 days of
treatment. Additionally, core cell-cycle genes CDKA1;1, CDKB2;1, CYCA3;1 and CYCB2;4 were down regulated in Arabidopsis
shoots suggesting, in part, their role in inhibition of shoot growth. The present work highlighted an autonomous and permanent
in vitro hairy root culture system as a valuable tool for studying allelopathic potential of apple, offering new perspective for allelopathy background elucidation in this important fruit species.

AB  - Brassica oleracea var. acephala is an important leafy vegetable that has been widely consumed as a high-nutrient, low-calorie food. Because of the plant’s biennial and self-incompatibility nature, biotechnological approaches are alternative way for propagation and breeding improvements. Since tissue culture studies have been focused in other B. oleracea representatives, the aim of the present study was to achieve effective regeneration protocol distinctive for collard greens, and evaluate the total phenolic content and antioxidant activity of regenerants. The effect of 3 cytokinins [thidiazuron (TDZ), 6-benzyladenine (BA) and 6-furfuryladenine (kinetin, KIN)] at increasing concentrations (0, 5, 7.5, 10, 20 or 30 µM) in combination with tenfold lower concentration of 1-naphtaleneacetic acid (NAA) (0, 0.5, 0.75, 1, 2 or 3 µM, respectively) on the regeneration from hypocotyl slices was studied. Histological analysis revealed the two regeneration pathways, somatic embryogenesis and shoot organogenesis, simultaneously occurred in the same explant, regardless of the cytokinin/NAA combinations used. The regeneration frequency of 95.9%, with 7.5 morphogenic structures regenerated per explant, and the healthy appearance of regenerated plants indicated the optimal combination 20 µM TDZ + 2 µM NAA. TDZ at 5 µM provided the high somatic embryo proliferation rate by generation of secondary embryos (7.79) along with the lowest rate of their abnormalities. Embryo-developed plants were successfully acclimatised (above 90%). The plants regenerated and proliferated on TDZ-containing media had higher total phenolic content that correlated with the highest free radical scavenging activity (IC50 = 19.09 µg ml− 1).

AB  - Allelopathic plants exploit their chemical ‘weapons’ to prevail over the competition, suppress neighboring plants and consequentlyuse the available resources more efficiently. However, the investigation of plant allelopathic interactions in rhizosphere is difficultto perform because of its high complexity due to interactions of biotic and abiotic factors. Thus, autonomous, aseptic root culturesof apple (Malus × domestica Borkh.) could facilitate allelopathic studies. We report on the successful genetic transformation ofapple cultivars Melrose, Golden Delicious, Cadel and Gloster using ˇ Agrobacterium rhizogenes (Riker et al. 1930) Conn 1942 strain15834 and for the first time the establishment of apple autonomous and permanent in vitro hairy root cultures that could be usedas a new tool for apple allelopathic assays. Molecular characterization of transgenic hairy root lines was conducted to elucidatethe possible relationship between expression of T-DNA genes and root growth characteristics that include branching. Similar content of phenolic acids (chlorogenic, caffeic, syringic, p-coumaric and ferulic), glycosilated flavonoids (rutin, quercitrin, isoquercitrin,kaempferol-3-glucoside) and flavonoid aglycones (quercetin and naringenin), and dihydrochalcone phloridzin, was detected inuntransformed and transgenic apple root tissue by ultra high-performance liquid chromatography with mass spectrometry(UHPLC/(+/–)HESI–MS/MS) analyses, confirming that genetic transformation did not disturb secondary metabolite production inapple. Chlorogenic and caffeic acids and dihydrochalcones phloridzin and phloretin were detected as putative allelochemicalsexuded into the growth medium in which transgenic roots were maintained for 4 weeks. Apple hairy root exudates significantlyaffected shoot and root development and growth of test plant Arabidopsis thaliana (L.) Heynh. seedlings after 5 or 10 days oftreatment. Additionally, core cell-cycle genes CDKA1;1, CDKB2;1, CYCA3;1 and CYCB2;4 were down regulated in Arabidopsisshoots suggesting, in part, their role in inhibition of shoot growth.

AB  - Common centaury, Centaurium erythraea Rafn., represent the best known and the most investigated medicinal plant species of genus Centaurium. Centaury has been used for centuries in traditional medicine. Secondary metabolites such as bitter secoiridoid glucosides (gentiopicrin, swertiamarin and sweroside), xanthones (eustomin and demethyleustomin), and phenolic acids are the main constituents responsible for the therapeutic properties of centaury. Previous investigation showed that overexpression of the AtCKX genes in transgenic centaury plants did not result in a decrease of total cytokinin (CK) content, but in an altered CK profile leading to a decline of bioactive, the most important physiologically active group of CKs.The aim of this study was to investigate antibacterial and antifungal activity of transgenic centaury methanol extracts as well as pure secoiridoid and xanthone compounds on four Gram positive, four Gram negative bacteria and eight species of microfungi. All tested methanol extracts of control and transgenic AtCKX1 centaury shoots and roots showed better antibacterial activity, while pure compounds (gentiopicrin, swertiamarin, eustomin and demethyleustomin) showed better antifungal activity. The results obtained in this work suggest that centaury methanol extracts and pure compounds represent potential antimicrobials confirming the possibility of using these compounds in agronomy, veterinary, medicine or food industry.

AB  - Production of innovative drugs from natural products in controlled conditions plays an important role in modern pharmacology in order to tackle global health challenges. The potential of Gentiana utriculosa hairy roots, obtained by transformation with Agrobacterium rhizogenes A4M70GUS, as well as that of the shoots regenerated from them via somatic embryogenesis, for xanthone production was investigated. Gentiana utriculosa was shown to be a new source of xanthones, medicinal raw materials for different pharmaceutical applications, among which decussatin has been recently recognized as a prospective hepatoprotective and antiulcer compound. Decussatin and decussatin-1-O-primeveroside were detected in both hairy roots and transgenic shoots, while mangiferin, present in nontransformed plants, was not detected. Quantitative HPLC analysis revealed up to 4.5-fold higher decussatin production in hairy roots line 9 compared with the plants from the nature, and this clone was selected. It showed stable growth after more than two years of continuous subcultivation. Cultivation of hairy roots on solid medium was favorable for biomass production, while liquid culture was beneficial for decussatin and decussatin-1-O-primeveroside accumulation. Cytokinins kinetin or N6-benzyladenine promoted somatic embryo maturation and germination as well as multiplication of obtained plantlets, while active charcoal reduced hyperhydricity. Plants regenerated from selected hairy root line 9 comprised two TL-DNA inserts, as confirmed by Southern blot analysis. They accumulated at least 2.5-fold more decussatin then nontransformed plants. Therefore, these plants could be valuable material to create xanthone high-yielding cultivars of G. utriculosa.

AB  - Food demands of increasing human population dictate intensification of livestock production, however, environmental stresses could jeopardize producers' efforts. Forage legumes suffer from yield losses and poor nutritional status due to salinity increase of agricultural soils. As tools aimed to reduce negative impacts of biotic or abiotic stresses, proteinase inhibitors (PIs) have been promoted for biotechnological improvements. In order to increase tolerance of Lotus corniculatus L. to salt stress, serine PI, BvSTI, was introduced into this legume using Agrobacterium rhizogenes, with final transformation efficiency of 4.57%. PCR, DNA gel-blot, RT-PCR and in-gel protein activity assays confirmed the presence and activity of BvSTI products in transformed lines. Plants from three selected transgenic lines (21, 73 and 109) showed significant alterations in overall phenotypic appearance, corresponding to differences in BvSTI accumulation. Lines 73 and 109 showed up to 7.3-fold higher number of tillers and massive, up to 5.8-fold heavier roots than in nontransformed controls (NTC). Line 21 was phenotypically similar to NTC, accumulated less BvSTI transcripts and did not exhibit an additional band of recombinant trypsin inhibitor as seen in lines 73 and 109. Exposure of the transgenic lines to NaCl revealed different levels of salt stress susceptibility. The NaCl sensitivity index, based on morphological appearance and chlorophyll concentrations showed that lines 73 and 109 were significantly less affected by salinity than NTC or line 21. High level of BvSTI altered morphology and delayed salt stress related senescence, implicating BvSTI gene as a promising tool for salinity tolerance improvement trials in L. corniculatus.

AB  - Glutamine synthetase (E.C. 6.3.1.2) is a key enzyme of plant nitrogen metabolism that assimilates ammonia into glutamine. The Arabidopsis thaliana genome encodes one chloroplastic (GLN2) and five cytosolic (GLN1;1 – GLN1;5) isoforms with different expression patterns, kinetic properties, regulation and functions. Physiological roles of different isoforms have been elucidated mainly by studying knockout mutants. However, the role of GLN1;5, which is expressed in dry seeds, remains unknown. To clarifty the function of GLN1;5, we studied a GLN1;5 knockout line (GLN1;5KO) homozygous for T-DNA insertion within the GLN1;5. GLN1;5 deficiency results in a phenotype with slightly delayed bolting and fewer siliques. The dry weight of GLN1;5KO seeds was 73.3% of wild-type (WT) seed weight, with seed length 90.9% of WT seeds. Finally, only 18.33% of the mutant seeds germinated in water within 10 days in comparison to 34.67% of WT seeds. KNO3 strongly stimulated germination of both GLN1;5KO and WT seeds, while germination in the presence of increasing NH4Cl concentrations potentiated the differences between the two genotypes. It can be concluded that GLN1;5 activity supports silique development and grain filling and that it has a role in ammonium reassimilation in the seed, as well as assimilation and/or detoxification of ammonium from the environment.
