AB  - Eruca sativa is known in traditional medicine for its therapeutic effects, while young plants
are used as a salad or green food. Recently, the consumption of rocket has increased considerably,
so it has become very important for breeders. Plant tissue culture provides a platform to overcome
the problems in improving this species. In the present study, an efficient protocol for in vitro shoot
regeneration and propagation of recalcitrant rocket variety Domaća rukola was studied. Murashige
and Skoog (MS, 1962) medium containing 0.1 mg/L BA and frequent subculture over a period
of three weeks proved to be optimal for shoot multiplication with a multiplication index of over 3
and only 8.72% of hyperhydrated shoots without necrosis. Different concentrations of 2,4-D, BA, or
TDZ in combination with NAA, with or without the presence of AgNO3, were tested for de novo
shoot organogenesis (DNSO) from seedling explants. The hypocotyl explants cultured on MS with a
combination of TDZ1.0+NAA0.1+AgNO3 5.0 mg/L regenerated viable shoots with the highest rate
(25.38%) and an average number of 2.18 shoots per regenerating explant. Somatic embryogenesis
from immature zygotic embryos proved to be the best way to regenerate a recalcitrant rocket cultivar.
The highest embryogenic efficiency was achieved in explants cultured on MS medium containing
1.0 mg/L 2,4-D with a frequency of 76.64% and 5.13 mean number of regenerated somatic embryos
per explant, which were further converted into normal plants. Additionally, in vitro-produced rocket
shoots could serve as a possible promising source for the production of flavonoid kaempferol with
proven antioxidant properties.

AB  - Глиобластом je најчешћи и најагресивнији тип тумора централног нервног система код одраслих. Циљ ове студије је био да се процени антиглиомски потенцијал екстраката коренова Gentiana dinarica у култури U251 ћелија хуманог глиобластома. Метанолни екстракти су добијени из нетрансформисаних коренова G. dinarica (екстракт 1, Е1) и трансгених коренова добијених коришћењем два соја Agrobacterium rhizogenes: A4M70GUS (екстракт 2, Е2) и 15834/PI (екстракт 3, Е3). Трансформацијом коренова са A. rhizogenes стимулисана је продукција ксантона, секундарних метаболита са доказаним антиканцерским ефектом. За разлику од Е1 и Е2, Е3 је снажно инхибирао раст U251 ћелија, изазвао застој ћелијског циклуса у G2/M фази и повећао експресију маркера диференцијације – астроцитног глијалног фибриларног киселог протеина (GFAP) и неуронског β-тубулина. Е3 је стимулисао Akt/mTOR-зависну аутофагију, на шта је указивало повећање нивоа аутофагног маркера LC3-II протеина и појачана деградација селективне аутофагне мете протеина p62. Инхибиција аутофагије је спречила експресију маркера диференцијације, без утицаја на застој у ћелијском циклусу. Е3 је повећао и нивое оксидативног стреса у ћелији, а антиоксиданси N-ацетил цистеин (NAC) и витамин Е су инхибирали и аутофагију и диференцијацију U251 ћелија изазвану Е3. Активна компонента Е3 је највероватније ксантонски агликон норсверцијанин, најзаступљеније једињење у Е3. Норсверцијанин је, као и Е3, зауставио пролиферацију U251 ћелија у G2/M фази ћелијског циклуса и изазвао диференцијацију, аутофагију и оксидативни стрес. Резултати ове студије указују да би Е3 и норсверцијанин могли бити кандидати за диференцијациону терапију глиобластома.

AB  - This study presents the hypocotyl elongation of sunflower seedlings germinated under different light conditions. Elongation was rhythmic under diurnal (LD) photoperiods but uniform (arrhythmic) under free-running conditions of white light (LL) or darkness (DD). On the sixth day after the onset of germination, seedlings were entrained in all diurnal photoperiods. Their hypocotyl elongation was dual, showing different kinetics in daytime and nighttime periods. The daytime elongation peak was around midday and 1-2 h after dusk in the nighttime. Plantlets compensated for the differences in the daytime and nighttime durations and exhibited similar overall elongation rates, centered around the uniform elongation in LL conditions. Thus, plants from diurnal photoperiods and LL could be grouped together as white-light treatments that suppressed hypocotyl elongation. Hypocotyl elongation was significantly higher under DD than under white-light photoperiods. In continuous monochromatic blue, yellow, green, or red light, hypocotyl elongation was also uniform and very high. The treatments with monochromatic light and DD had similar overall elongation rates; thus, they could be grouped together. Compared with white light, monochromatic light promoted hypocotyl elongation. Suppression of hypocotyl elongation and rhythmicity reappeared in some combination with two or more monochromatic light colors. The presence of red light was obligatory for this suppression. Plantlets entrained in diurnal photoperiods readily slipped from rhythmic into uniform elongation if they encountered any kind of free-running conditions. These transitions occurred whenever the anticipated duration of daytime or nighttime was extended more than expected, or when plantlets were exposed to constant monochromatic light. This study revealed significant differences in the development of sunflower plantlets illuminated with monochromatic or white light.

AB  - Eruca sativa (rocket, Brassicaceae), is known in traditional medicine for its therapeutic, while young plants are used as salad, vegetable, or green foods. Genetic improvement of the rocket has been limited due to the appearance of biennial plants and the requirement for isolation barriers. Plant tissue culture offers a platform to overcome existing barriers to improving this species. The present study aimed to achieve a feasible protocol for shoot regeneration and propagation of rocket cv. Domaća rukola and to evaluate the use of AgNO3 to improve regeneration efficiency. Proliferation of shoots from seedling epicotyl, shoot organogenesis from root, hypocotyl and cotyledon seedling explants, and somatic embryogenesis from immature zygotic embryos were studied. Murashige and Skoog (MS) basal medium in combination with a low KIN concentration of 0.1 mg l-1 with frequent subculture over a period of 3 weeks was found to be optimal for shoot multiplication with a multiplication index of almost 3 and only 9.3% of vitrified shoots without necrosis. Different concentrations of 2,4-D, BA or TDZ in combination with NAA and with or without AgNO3 were tested for shoot regeneration from seedling explants. As a result, the hypocotyl explants cultured on MS with a combination of TDZ 1.0+NAA 0.1+AgNO3 5.0 mg l-1 provided healthy shoots with a satisfactory regeneration rate of 25.4% and 2.2 mean number of shoots per regenerating explant. Immature zygotic embryos cultured on MS medium containing 1.0 mg l-1 2.4-D showed the highest regeneration frequency (78.76%) as well as the number of regenerated somatic embryos per explant (5.13) with low incidence of callusing and necrosis. KIN at 0.5 mg l-1 enabled the best conversion of somatic embryos into healthy plants (22.5%). The results provide an opportunity to use established regeneration protocols in rocket breeding improvement programs.

AB  - Gentiana clusii Perr. & Song. (Gentianaceae), is a rare plant species found in the Alps, the Pyrenees, the Black Forest Mountains and the Carpathians. G. clusii is endemic for Europe which implies the need for its conservation. G. clusii plants were collected at fruitful stage in June 2015 at Velika Planina Mountain, Republic of Slovenia. Seeds of G. clusii were germinated on MS basal medium. Shoots cultured on WPM + 0.5 mg/L KIN were used as starting material in propagation and rooting experiments. Medium with IBA at 0.5 mg/L was chosen as optimal for rooting. HPLC screening of secondary metabolites of wild plants collected in nature and in vitro plants revealed the presence of two main classes of compounds typical for gentians – secoiridoids and xanthones. Secoiridoids gentiopicrin and sweroside were identified in both aerial parts of wild plants and shoots of in vitro plants, while root extracts contained amarogentin in addition. Aerial parts of wild plants contained gentiacaulein-1-O-primeveroside as dominant xanthone glycoside. HPLC also revealed the presence of gentiakochianin-1-O-primeveroside, norswertianin-1-O-primeveroside, 1,8- dihydroxy-3-methoxy-7-O-primeverosyl xanthone, and xanthone aglycons- norswertianin, gentiacaulein, and gentiakochianin. HPLC analysis shown that in vitro culture considerably promoted the production of secondary metabolites in G. clusii. The selected protocol for shoot propagation (WPM + 0.5 mg/L KIN) increased the content of sweroside, gentiopicrin and norswertianin-1-O-primeveroside for more than 2-fold compared with the wild plants. IBA promoted norswertianin-1-O-primeveroside and norswertianin production in root cultures; their contents were enhanced 6.4- and 18.6-fold, respectively, compared with the wild plants. The extract of these roots displayed high antioxidant capacity. The established shoot and root propagation protocols facilitate in vitro conservation of G. clusii, and provides a promising tool for the large scale production of valuable secoiridoids and xanthones.

AB  - Flower strips of French Marigold are commonly used pest repellents in potato fields. However, the effect of French Marigold volatiles on potato metabolism, physiology and induced defense is unknown. Thus, a microarray transcriptome analysis was performed to study the effects of French Marigold essential oil (EO) on laboratory-grown potato. After 8 h of exposure to EO, with gas chromatography/mass spectrometry (GC/MS)-detected terpinolene and limonene as dominant compounds, 2796 transcripts were differentially expressed with fold change >2 compared to expression in controls. A slightly higher number of transcripts had suppressed expression (1493 down- vs. 1303 up-regulated). Since transcripts, annotated to different photosynthesis-related processes, were mostly down-regulated, we selected a set of 10 genes involved in the leaf starch metabolism pathway, and validated microarray patterns using quantitative reverse transcription polymerase chain reaction (RT-qPCR). Except for decreased synthesis and induced decomposition of starch granule in leaves, 8 h long EO exposure slightly elevated the accumulation of sucrose compared to glucose and fructose in subjected potato plants. An in vitro feeding bioassay with Colorado potato beetle showed that EO-induced alternations on transcriptional level and in the sugars’ metabolism caused the enhancement of feeding behavior and overall development of the tested larvae. Results of comprehensive analysis of transcriptional responses in potato exposed to French Marigold EO provide a basis for further elucidation of molecular mechanisms underlying eco-physiological interactions in companion planting cropping systems.

AB  - In vitro shoot culture of the endangered medicinal plant Gentianella lutescens was established from epicotyl explants cultured on MS basal medium with 0.2 mg L−1 6-benzylaminopurine (BA) and evaluated for xanthones content for the first time. Five shoot lines were obtained and no significant variations in multiplication rate, shoot elongation, and xanthones profile were found among them. The highest rooting rate (33.3%) was achieved by shoots treated for 2 days with 5 mg L−1 indole-3-butyric acid (IBA) followed by cultivation in liquid PGR-free ½ MS medium for 60 days. HPLC analysis revealed the lower content of xanthones—mangiferin, bellidifolin, demethylbellidifolin, demethylbellidifolin-8-O-glucoside and bellidifolin-8-O-glucoside—in in vitro cultured shoots compared to wild growing plants. The increasing concentration of sucrose, sorbitol and abiotic elicitors salicylic acid (SA), jasmonic acid (JA) and methyl jasmonate (MeJA) altered shoot growth and xanthone production. Sucrose and sorbitol applied at the highest concentration of 233.6 mM increased dry matter percentage, while SA at 100 μM promoted shoot growth 2-fold. The increased sucrose concentration enhanced accumulation of xanthones in shoot cultures 2–3-fold compared to the control shoots. Elicitors at 100–300 μM increased the accumulation of mangiferin, demethylbellidifolin-8-O-glucoside, and bellidifolin-8-O-glucoside almost equally, while MeJA at the highest concentration of 500 μM enhanced amount of aglycones demethylbellidifolin and bellidifolin 7-fold compared to the control. The obtained results facilitate conservation of G. lutescens and pave the way for further research on large-scale shoot propagation and production of pharmacologically active xanthones.

AB  - The hairy root clones of Gentiana dinarica cl-B, cl-D, cl-3, and cl-14 were cultivated in parallel in diverse simple bioreactors, including temporary immersion systems RITA® (TIS RITA®), bubble column bioreactors (BCB), and Erlenmeyer flasks (EF), and evaluated for biomass production and xanthone content. The obtained results showed that TIS RITA® and BCB containing ½ MS medium with 4% sucrose provided equally good growth conditions in which the majority of the clones displayed the higher percentage of dry matter (DM%), and xanthones norswertianin-1-O-primeveroside (nor-1-O-prim) and norswertianin production than those cultivated in EF. Thin and well branched hairy root clone cl-B grown in BCB for 7 weeks was superior regarding all growth parameters tested, including growth index (19.97), dry weight (2.88 g), and DM% (25.70%) compared to all other clones. Cl-B cultured in TIS RITA® contained the highest amount of nor-1-O-prim (56.82 mg per vessel). In BCB with constant aeration, cl-B accumulated the highest norswertianin content reaching 18.08 mg/vessel. The optimized conditions for cultivation of selected G. dinarica hairy root clones in highly aerated TIS RITA® and BCB systems contribute to the development of bioreactor technology designed for the large scale commercial production of xanthones nor-1-O-prim and norswertianin.

AB  - Research on phototropic (PT) bending in sunflower (Helianthus annuus L. cv. Kondi (Syngenta)) seedling hypocotyls presented herein focused on a comparison of diurnal and free-running photoperiods with the aim of explaining the development of diurnal rhythmicity. PT bending magnitudes and lag phase duration exhibited strong daily rhythmicity in all diurnal photoperiods, contrasting with the uniform PT bending response to constant light (CL) conditions. Plants had a daytime maximum for PT bending magnitudes in experiments starting around midday and a minimum in the dark period in those starting 4 h after dusk. Plants could compensate for large differences in the daytime duration of diurnal photoperiods. They required the first 4 h of darkness to recover and synchronize the PT bending and to start increasing the magnitudes of PT bending. The daily pattern of lag phase duration changes was similar but inverted, showing that synchronization also occurred during nighttime. Darkness was not required for PT bending under CL conditions, however, during diurnal photoperiods it enabled the establishment of diurnal rhythmicity and synchronized changes in PT bending capacity to occur when needed, providing maximal values at midday and minimal during the nighttime. Under prolonged duration of daytime corresponding to the start of CL condition, plantlets rapidly abandoned circadian regulation, their PT bending response becoming arrhythmic.

AB  - In this study, tansy (Tanacetum vulgare L.) in vitro culture was established from seeds collected from natural populations. The multiplication of plantlets was conducted through shoot tips that exhibited potent apical growth and regeneration capacities on basal medium (BM), without the addition of any plant growth regulators (PGRs). PGRs were also omitted for the establishment and cultivation of tansy root cultures. Both abaxial and adaxial leaf surfaces of in vitro micropropagated plantlets were covered with glandular biseriate trichomes. Histochemical staining showed that glandular secretions were rich in lipid and terpene compounds, confirmed by GC-MS analysis of essential oil (EO). In the total EO, similar portions of oxygenated monoterpenes (38.5% m/m) and oxygenated sesquiterpenes (22.6% m/m) were detected. Chemical profiles of methanol extracts of in vitro cultured tansy shoots and roots varied in quantity and quality from those obtained from wild-growingtansy. HPLC analysis indicated that the methanol extracts of in vitro cultured roots were the richest in 3,5-O-dicaffeoylquinic acid (3,5-O-DCQA), in which the concentration was 6 times higher (10.220 mg/g DW) than that in the extract obtained from roots of wild-growing tansy (1.684 mg/g DW). This result is noticeable in the manner of industrial production of biologically active 3,5-O-DCQA that has been shown to have antioxidant, hepatoprotective, antiviral, antimutagenic, and immunomodulatory activity. Biotechnological interventions on secondary metabolite production taking place in trichomes could further enhance the production of some important tansy metabolites and further investigation will be directed toward the elucidation of the pharmaceutical potential of tansy in vitro obtained metabolites, as mixtures or single moieties.

AB  - Shoot and root in vitro culture of endemic European species Gentiana clusii was established for the first time. The effects of different concentrations of benzyl adenine (BA), 6-phurphurylaminopurine (KIN), indole-3-butyric acid (IBA) and naphthalene acetic acid (NAA) on shoot propagation and rooting of G. clusii were investigated. The optimal in vitro conditions for shoot propagation and long-term maintenance were achieved using woody plant medium (WPM) supplemented with 0.5 mg l-1 KIN, and subsequent application of IBA at 0.5 mg l-1 significantly improved rooting of these shoots. Root culture was established from excised root tips cultured in ½ MS liquid media with increasing concentrations of IBA (0.1-1.0 mg l-1). A high root growth rate and considerable biomass yield were obtained by addition of 1.0 mg l-1 IBA. HPLC analysis revealed that in vitro culture considerably promoted the production of secondary metabolites in G. clusii. The selected protocol for shoot propagation (WPM + 0.5 mg l-1 KIN) increased the content of sweroside, gentiopicrin and norswertianin-1-O-primeveroside (N-1-P) for more than 2-fold compared with the wild plants. IBA promoted N-1-P and norswertianin production in root cultures; their contents were enhanced 6.4- and 18.6-fold, respectively, compared with the wild plants. The extract of these roots displayed the highest antioxidant capacity (IC50 = 66.57 μg ml-1). The established shoot and root propagation protocols facilitate in vitro conservation of G. clusii, and provides a promising tool for the large scale production of valuable secoiridoids and xanthones.

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  - Kohlrabi (Brassica oleracea var. gongylodes), with its edible stem tuber formed at the base of
the plant stem, presents a valuable source of nutrients. The potential effects of plant growth regulators
(PGRs), as well as various concentrations of different sugars on the in vitro development of kohlrabi were
studied. Ten-day-old kohlrabi seedlings were cultivated in vitro for 5 weeks at 18±2°C on half-strength
MS media containing different concentrations of carbon source such as sucrose, fructose, glucose, xylose
and mannitol, combined with or without specific plant growth regulators (N6-benzyladenine (BA),
gibberellic acid (GA3), 2,3,5-triiodobenzoic acid (TIBA)). Results showed no tuber formation in all
treatments, but growth and development of treated kohlrabi seedlings was significantly affected in a
distinctive manner, with a variety of morphological traits being altered in comparison to matching
controls.

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.

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  - 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  - 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  - BACKGROUND Glioblastoma multiforme (GMB) is the most malignant of all brain tumors with poor prognosis. Anticancer potential of xanthones, bioactive compounds found in Gentiana dinarica, is well-documented. Transformation of G. dinarica roots with Agrobacterium rhizogenes provides higher xanthones accumulation, which enables better exploitation of these anticancer compounds. HYPOTHESIS/PURPOSE The aim of this study was to investigate antiglioma effect of three different G. dinarica extracts: E1—derived from untransformed roots, E2—derived from roots transformed using A. rhizogenes strain A4M70GUS, and E3—derived from roots transformed using A. rhizogenes strain 15834/PI. Further, mechanisms involved in anticancer potential of the most potent extract were examined in detail, and its active component was determined. METHODS The cell viability was assessed using MTT and crystal violet test. Cell cycle analysis, the expression of differentiation markers, the levels of autophagy, and oxidative stress were analyzed by flow cytometry. Autophagy and related signaling pathways were assessed by immunoblotting. RESULTS E3, in contrast to E1 and E2, strongly reduced growth of U251 human glioblastoma cells, triggered cell cycle arrest in G2/M phase, changed cellular morphology, and increased expression of markers of differentiated astrocytes (glial fibrillary acidic protein) and neurons (β-tubulin). E3 stimulated autophagy, as demonstrated by enhanced intracellular acidification, increased microtubule-associated light chain 3B (LC3-I) conversion to autophagosome associated LC3-II, and decreased level of selective autophagy target p62. Induction of autophagy was associated with Akt-dependent inhibition of main autophagy suppressor mammalian target of rapamycin (mTOR). Both genetic and pharmacological inhibition of autophagy suppressed the expression of differentiation markers, but had no effect on cell cycle arrest in E3-treated cells. E3 stimulated oxidative stress, and antioxidants vitamin E and N-acetyl cysteine inhibited autophagy and differentiation of E3-treated U251 cells. The most prevalent compound of E3, xanthone aglycone norswertianin, also arrested glioblastoma cell proliferation in G2/M phase and induced glioblastoma cell differentiation through induction of autophagy and oxidative stress. CONCLUSION These results indicate that E3 and its main active component norswertianin may serve as a potential candidate for differentiation therapy of glioblastoma.

AB  - When attacked, plants activate defense mechanisms including volatile emission. Besides having
a pest repellent effect, volatiles can induce defense response in surrounding unharmed plants.
French marigold (Tagetes patula L.) essential oil (EO) was isolated from the above-ground parts
of plants collected from nature by hydrodistillation using Clevenger apparatus. GC/MS analysis
revealed the presence of 42 compounds, of which 97% (32 compounds) have been identified.
The monoterpene fraction was dominant (76.9%) with terpinolene (32.4%) and limonene (14.7%)
as the most abundant compounds. In order to investigate the potential of marigold EO to induce
the defense of potato, we analyzed 3 genes related to the induced resistance (IR): pathogenesis
related PR-2 and PR-5 genes, and proteinase inhibitor Pin2. The potato plants were exposed to EO
volatiles during 4, 8 and 12 h. Two leaves of EO-treated or untreated control plants were collected,
and plants were then additionally injured by mechanically wounding leaves across the leaf surface.
After 24 h of wounding, another two leaves from each plant were collected and expression
of the IR related genes was analyzed by qPCR method. EO induced altered expression of PR genes,
while Pin2 wasn’t affected by the treatment. Mechanical wounding increased the expression of
all genes after 4 and 8 h of EO treatment, with up to 4-fold change in PR-2. However, in plants
exposed to EO for 12 h before wounding, the level of transcription in PR-2 and Pin2 was similar to
that detected in untreated controls. These findings support the efforts for environmentally-safe
pest control in crops by using natural compounds.

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  - This study investigated the role of antioxidant system of Alyssum markgrafii, during long-term exposure to 0.5 or 1 mM NiCl2 × 6H2O in vitro. Applied methodology included sample preparation protocol which reduces oxidation of key metabolites along with novel luminescent method and well-established photometric procedures. During 5-week treatments, plants accumulated 1121 and 2470 ppm of Ni2+ respectively, followed by severe growth retardation, chlorophyll degradation and peroxidation of lipids. These effects were more pronounced after 1 mM Ni2+ treatment and additionally accompanied by increased water loss. Activities of luminol-converting peroxidases and glutathione reductase upon 0.5 mM treatment were increased while catalase and superoxide dismutase were diminished. The fact that these two groups of enzymes run in antiparallel might suggest functional redistribution between antioxidant enzymes rather than orchestrated action to prevent oxidative damage. Total antioxidant capacity (TAC) was also increased after 0.5 mM treatment which coincided with increased GR activity and elevated glutathione content indicating this low molecular weight antioxidant as an important factor associated with nickel tolerance. This study also emphasizes the possible important role of luminol-converting peroxidases in nickel hyperaccumulation, although they are not considered as antioxidant enzymes sensu stricto since some of them can also produce reactive oxygen species as well.

AB  - Three hairy root clones of Hypericum perforatum (HR 2, HR 15 and HR 27) transformed with Agrobacterium rhizogenes A4M70GUS and their corresponding regenerated shoot culture clones (HRRS) were compared for differences in growth, production of phenolic compounds, antioxidant and antimicrobial activities. Transgenic clones were selected on the basis of morphological evaluation, genetic and molecular analyses. The clone HR 2 had the highest biomass accumulation, while HR 27 showed the highest shoot regeneration potential. The total phenolics and flavan-3-ols were enhanced in all tested transgenic cultures, while total flavonoids and hypericins were augmented in HRRS clones compared to non-transformed shoots. The HRRS clones produced substantial amounts of chlorogenic acid and 3-p-coumaroylquinic acid. Regarding the flavonoids, they produced significant contents of luteolin hexoside (HRRS 2), quercitrin and quercetin (HRRS 15) and isoquercetin (HRRS 27), while HR 2 and 15 accumulated 4-O-methylkaempferol-O-hexoside and quercetin 6-C-glucoside, respectively. The HR 15 was promising for the production of catechin and procyanidin derivatives and together with its HRRS clone exhibited a high potential for hyperforin and adhyperforin production. All identified naphtodianthrones were confirmed in HRRS 2 and 15 clones. Among xanthones, mangiferin was found as the major compound in HRRS, while trihydroxy-1-metoxy-C-prenyl xanthone was dominant in HR clones. Antimicrobial activity of transgenic cultures revealed that HRRS 15 strongly inhibited the growth of Bacillus cereus, Micrococcus flavus, Pseudomonas aeruginosa and Escherichia coli. Altogether, H. perforatum HR and HRRS cultures could be proposed as promising experimental systems for enhanced production of phenolic compounds with antioxidant and antibacterial properties.

AB  - The effect of abiotic (salicylic acid, jasmonic acid and methyl jasmonate) and biotic (chitosan and yeast extract) elicitors on the growth and xanthone accumulation in two hairy root clones of Gentiana dinarica Beck. was studied. The obtained results showed that clone 3 was more responsive to elicitor treatment than clone D. The production of dominant xanthone norswertianin-1-O-primeveroside was not significantly affected by either of the abiotic elicitor tested but was stimulated with chitosan treatment. The highest concentrations of all elicitors strongly increased the content of xanthone aglycone norswertianin, but simultaneously reducing the production of its glycoside norswertianin-1-O-primeveroside. The most efficient in enhancing norswertianin production was a 7-day treatment with salicylic acid (200 μM) and chitosan (50 mg l− 1), which yielded a 7.7- and a 24-fold increase in norswertianin content, respectively. In addition, treatment with biotic elicitors caused the occurrence of new xanthone compounds that were not detected in other samples. Free radical scavenging activity of xanthones was carried out by DPPH assay, and norswertianin showed the strongest activity.

AB  - Intact and wounded shoots of in vitro cultured potato were investigated in situ to determine how their phototropic (PT) bending capacity was affected by water availability and exogenous auxin supplementation. Wounding strongly decreased PT bending but it recovered upon supplementation of water, auxin or both. Intact shoots required neither water nor auxin, while shoot segments required both. Shoot cuttings required only water, while, like shoot segments, decapitated shoots had a strong requirement for auxin. Water supplementation was beneficial in all treatments and PT bending was not affected in cultures that were submerged in water for a short period. Sucrose and inorganic salts present in the medium strongly affected PT bending capacity of cultures, favouring combinations with lower concentrations of both. Sucrose alone strongly promoted PT bending up to a concentration of 5%. Osmotic shock induced by the addition of small volumes of highly concentrated carbohydrate solutions (sucrose, glucose or sorbitol) induced a rapid but transient decline in PT bending capacity. These results indicate that water availability is a major factor that affects PT bending in potato plantlets.
