AB  - Phloretin is a phenolic compound from the apple that belongs to the group of dihydrochalcones. The genus Malus is a uniquely rich source of dihydrochalcones, accounting for about 97% of the total phenolic compounds in apple leaves and 10-20% of the dry weight of the leaf tissue. Due to its typical dihydrochalcone structure, phloretin is a highly reactive molecule that interacts efficiently with many biological macromolecules. Its reactivity leads to remarkable antioxidant and medicinal properties that have been extensively studied in mammals and humans. However, knowledge about the effects of phloretin on plant organisms is rather scarce. The phytotoxicity of phloretin in plants was first documented by our research group when phloretin was recognised as a potent allelochemical of the apple tree with deleterious effects in plant species outside the genus Malus. Research on the model plant Arabidopsis [Arabidopsis thaliana (L.) Heynh] named the disruption of auxin homeostasis in the roots as the main mechanism of the phytotoxic effect of phloretin. The present study complements previous research with new insights into the ultrastructural changes in leaf mesophyll cells that underlie the growth arrest and decay of the aerial parts of Arabidopsis seedlings exposed to phloretin. The effects of phloretin are closely linked to the ultrastructural damage in the leaf mesophyll cells and range from mild effects with short-term treatment to severe effects with long-term treatment. Transmission electron microscopy revealed changes in the morphology of the cell wall, changes in thylakoid organisation, swelling and displacement of chloroplasts after short-term treatment. A significant decrease in the number of starch granules and chlorophyll content in the leaves reflected impaired chloroplast function leading to depletion of starch reserves, starvation of cells and recruitment of micro- and macroautophagic processes for self-maintenance leading to programmed cell death after long-term treatment with phloretin. These results confirm that the sites of action of phloretin in plant and animal cells do not coincide, confirming the safety of its potential application as a new bioherbicidal agent for humans and animals.

AB  - Root-exuded compounds play a key role in the regulation of plant allelopathic interactions. In contrast to
numerous studies showing that many secondary metabolites have an allelopathic function, evidence of
exudation of phytohormones into the rhizosphere and their involvement in allelopathic interactions is scarce.
We postulated that phytohormones secreted by roots into the environment may act as allelochemicals that
affect the growth performance of neighboring plants. Hairy root culture media of two distinct species, the fruit
tree species Malus domestica cv. Golden delicious[1] and the herbaceous weed species Chenopodium murale
[2,3] were collected and analyzed by ultra-high-performance liquid chromatography coupled with tandem mass
spectrometry (UHPLC-MS/MS). We found that most of plant growth substances exuded by the hairy roots of
C. murale and M. domestica were assorted from fraction A (96.8% and even 98.9%, respectively) including
OxIAA, PAA, SA, BzA, and ABA, with SA and BzA being the most abundant, whereas those from fraction B,
including cytokinins and the ethylene precursor ACC, accounted for only 1% of the regulatory substances
detected in both species. Exogenous application of SA at concentrations released by the hairy roots of the
respective plant species and accumulated in the culture media for four weeks significantly affected the hairy
root growth of the other species and also the shoot and root growth of the Arabidopsis seedlings. The
disruptive effect of SA in the exuded concentration on the membrane potential of Arabidopsis root cells was
determined. The data obtained would be useful for designing further studies aimed at elucidating the
contribution and role of exuded phytohormones to overall allelopathic potential of these two plant species.

AB  - Flax seeds stored in unfavorable conditions were exposed to static magnetic fields (SMFs)
of 50–350 mT for 20–120 min to overcome low germination and quality. Seed germination increased
slightly with increasing strength of SMF and duration of treatment. Seed germination from 89% to
100% was achieved in SMF treatments of 150 mT (120 min), 200 mT (80–120 mT), 250 mT (60–120 min),
300 mT (40–120 min), and 350 mT (40–120 min). In these treatments, germination was 2.78- to 3.12-fold
higher than in the control after 10 days. Treatments with 350 mT for 100 and 120 min showed the
best results in germination (100%), as well as a 26.81-fold increase in vigor I, 28.69-fold increase in
vigor II, 1-fold increase in chlorophyll a, 0.84-fold in chlorophyll b, 0.46-fold increase in carotenoid
content, and 2.63-fold increase in catalase activity compared to the control after 10 days. Also,
SMF treatment of 350 mT (20–120 min) reduced cell leakage and electrical conductivity by 1-fold

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  - Apple species are exclusively rich source of dihydrochalcones phloretin and phloridzin, phenolic compounds with elusive role in planta but suggested auto-allelochemical features related to 
‘apple replant disease’ (ARD). Our recent study emphasized phytotoxic action of phloretin towards 
other plant species such as model plant Arabidopsis as a consequence of disturbed auxin homeostasis in roots and altered chloroplast structure and function. Since elevated production and 
accumulation of reactive oxygen species (ROS) in plant cells is the one of the most common effect 
of allelochemicals, this study aimed to analyze the antioxidant status of Arabidopsis seedlings 
treated with phloretin. Total phenolic content (TPC) and total antioxidant capacity (TAC), as well 
as antioxidant enzymes activities were determined spectrophotometrically in treated and control 
seedlings at 5th and 10th day after germination (DAG). TAC increased c.a. 280% and 200% relative to 
control at 5th and 10th DAG respectively, presumably due to highly elevated TPC in treated seedlings (c.a. 150%). At the same time, the activity of antioxidant enzymes significantly decreased. The 
activity of catalase (CAT) was reduced by c.a. 40% and guaiacol peroxidase (POD) activities by 93% 
and 47% at 5th and 10th DAG, respectively. The activity of superoxide dismutase (SOD) was reduced 
by 55% and 18% at 5th and 10th DAG, respectively. The burst of antioxidant capacity of phloretin 
treated Arabidopsis seedlings resulted in significantly decreased antioxidant enzymes activities 
presumably due to strong antioxidant properties of absorbed phloretin. However, phloretin inhibition of antioxidant enzymatic activity due to its direct interaction with enzymes is object of 
further investigation.

abstract = "Apple species are exclusively rich source of dihydrochalcones phloretin and phloridzin, phenolic compounds with elusive role in planta but suggested auto-allelochemical features related to 
‘apple replant disease’ (ARD). Our recent study emphasized phytotoxic action of phloretin towards 
other plant species such as model plant Arabidopsis as a consequence of disturbed auxin homeostasis in roots and altered chloroplast structure and function. Since elevated production and 
accumulation of reactive oxygen species (ROS) in plant cells is the one of the most common effect 
of allelochemicals, this study aimed to analyze the antioxidant status of Arabidopsis seedlings 
treated with phloretin. Total phenolic content (TPC) and total antioxidant capacity (TAC), as well 
as antioxidant enzymes activities were determined spectrophotometrically in treated and control 
seedlings at 5th and 10th day after germination (DAG). TAC increased c.a. 280% and 200% relative to 
control at 5th and 10th DAG respectively, presumably due to highly elevated TPC in treated seedlings (c.a. 150%). At the same time, the activity of antioxidant enzymes significantly decreased. The 
activity of catalase (CAT) was reduced by c.a. 40% and guaiacol peroxidase (POD) activities by 93% 
and 47% at 5th and 10th DAG, respectively. The activity of superoxide dismutase (SOD) was reduced 
by 55% and 18% at 5th and 10th DAG, respectively. The burst of antioxidant capacity of phloretin 
treated Arabidopsis seedlings resulted in significantly decreased antioxidant enzymes activities 
presumably due to strong antioxidant properties of absorbed phloretin. However, phloretin inhibition of antioxidant enzymatic activity due to its direct interaction with enzymes is object of 
further investigation.",

AB  - Phloretin is phenolic compound specifically produced in apple tree species and secreted into the soil as a response to biotic and abiotic factors. Since our previous results indicated roots as the primary site of phloretin phytotoxic action, this study focused on assessment of phloretin effects on the root growth of weed (Chenopodium murale and Lotus corniculatus),  crop (Solanum tuberosum) and woody species (Castanea sativa and Malus × domestica Borkh.). Significant decrease in root biomass production in liquid growth medium enriched with 500 µM phloretin was observed both after 2 and 4 weeks of treatment in all tested species. The percentages of roots growth inhibition were as follows: Chenopodium murale (95% and 89,1%), Lotus corniculatus (69,4% and 81,8%), Solanum tuberosum (88,4% and 84,7%), Castanea sativa (85,6% and 100%) and Malus × domestica Borkh. (65,3% and 87,4%, respectively). Total antioxidant capacity (TAC), total phenolic content (TPC), as well as antioxidant enzymes activities were determined spectrophotometrically in treated and control Chenopodium murale roots after 4 weeks of phloretin treatment. TAC increased 44,1% presumably due to elevated TPC (25,8%) in treated roots. However, there were no significant differences in catalase (CAT), guaiacol peroxidase (POD) and superoxide dismutase (SOD) activities in control and treated roots after 4 weeks of treatment. Increased antioxidant activity in treated roots is presumably the consequence of known phloretin antioxidant potential.

AB  - Phloretin is a phenolic compound unique for apple (Malus × domestica Borkh.) species. Our 
research group recently reported phytotoxic potential of phloretin towards other plant species 
such as model plant Arabidopsis. Since sugars in in vitro growth media could modulate plant 
metabolism, we analyzed phloretin effects on Arabidopsis seedlings grown on the medium with out sucrose and myoinositol (WSM) but enriched with different concentrations of phloretin (0 
to 1500 µM). Phloretin treatment on WSM induced seedlings growth retardation at much lower 
concentrations compared to sucrose and myoinositol enriched medium. Inhibition of primary 
root and leaf growth, and lateral root emergence increased with both phloretin concentration 
and treatment duration (maximal 85.2%, 30.4% and 46.5% at 1500 µM phloretin at 15 days after 
germination - DAG, respectively). Prolonged cultivation (4 weeks) at phloretin concentrations over 
500 µM induced complete growth stagnation and necrosis of the leaves. Transmission electron 
microscopy reviled relocation of chloroplasts within mesophyll cells, shape change into spherical 
form, as well as ultrastructural changes in thylakoid organization in leaves of 10 DAG-old seedlings 
treated with 250 or 500 µM phloretin. Significantly decreased number of starch grains in chloro plasts and chlorophyll a and b content in leaves reflected impaired function of chloroplasts due 
to ultrastructural changes. Phloretin also induced cell wall undulation and folds that resulted in 
irregularly shaped mesophyll cells. The presented study revealed that beside roots that had been 
previously emphasized as primary targets of phloretin action, leaves were also significantly affect ed by phloretin treatment, especially in the aspect of photosynthetic apparatus

AB  - Phloretin, phenolic compound found exclusively in Apple trees, possesses bioherbicidal potential towards other plant species. Our recent studies emphasized phloretin phytotoxic action towards model plant Arabidopsis [Arabidopsis thaliana (L.) Heynh.] as a consequence of disturbed auxin homeostasis in roots and disrupted normal leaf cell function due to chloroplast ultrastructural changes and decreased chlorophyll a and b levels. Given the known phloretin reactivity that results from its flexible dihydrochalcones structure, this study aimed to elucidate phloretin direct effects on the root plasma membrane, as well as phloretin post-treatment metabolism in Arabidopsis plants. Electrophysiological measurements were performed to assess real-time response of root plasma membrane to exogenously applied phloretin. Exposing Arabidopsis roots to a 250 µM phloretin resulted in rapid and significant depolarization of the root membrane potential with amplitude of about 47mV that confirmed high sensitivity of Arabidopsis to phloretin treatment. Reverse-phase liquid chromatography with mass spectrometry (LC-MS) was used to evaluate post-treatment metabolism of phloretin in Arabidopsis seedlings grown on 500 µM phloretin enriched medium for 10 days. Analyses revealed that phloretin underwent intensive glycosylation within plant tissues. Dominant peaks from treated plants showed a palette of phloretin derivatives mainly mono- and di-glycosides. Their quantity was significantly higher than in control plants, suggesting high uptake and metabolic interconversion of phloretin as an attempt of phloretin detoxification and/or preparation for vacuolar sequestration.

AB  - Phloridzin and phloretin are dihydrochalcones highly specific to domestic apple (Malus × domestica

in apple trees replanted on lands that previously supported apple orchards. Physiological basis of phloridzin and phloretin autotoxicity are ultrastructural and molecular alterations that include increased catalase, peroxidases and superoxide dismutase activities, raised malondialdehyde and proline contents, and
high expression of genes involved in cell defence system. The latest research on model plant Arabidopsis

AB  - Apple species are the unique naturally rich source of dihydrochalcones, phenolic compounds with an elusive role in planta, but suggested auto-allelochemical features related to “apple replant disease” (ARD). Our aim was to elucidate the physiological basis of the phytotoxic action of dihydrochalcone phloretin in the model plant Arabidopsis and to promote phloretin as a new prospective eco-friendly phytotoxic compound. Phloretin treatment induced a significant dose-dependent growth retardation and severe morphological abnormalities and agravitropic behavior in Arabidopsis seedlings. Histological examination revealed a reduced starch content in the columella cells and a serious disturbance in root architecture, which resulted in the reduction in length of meristematic and elongation zones. Significantly disturbed auxin metabolome profile in roots with a particularly increased content of IAA accumulated in the lateral parts of the root apex, accompanied by changes in the expression of auxin biosynthetic and transport genes, especially PIN1, PIN3, PIN7, and ABCB1, indicates the role of auxin in physiological basis of phloretin-induced growth retardation. The results reveal a disturbance of auxin homeostasis as the main mechanism of phytotoxic action of phloretin. This mechanism makes phloretin a prospective candidate for an eco-friendly bioherbicide and paves the way for further research of phloretin role in ARD.

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  - 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  - 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  - 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. The present work highlighted an autonomous and permanentin 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  - Since the investigation of plant allelopathic interactions in the rhizosphere is difficult to perform
because of its high complexity, microbial and environmental factors interactions, the generation
of autonomous root culture could be appropriate system for the studies of allelopathic potential of apple (Malus x domestica Borkh.). Thus, we have focused our efforts on the generation
of transformed hairy-roots in apple cv. Golden Delicious using the 15834 strain of Agrobacterium
rhizogenes. The agrobacteria inoculation by dipping the basal cut off end of the stem of in vitro
grown apple shoots into bacterial suspension proved to be the best option for transformation,
providing efficiency of 39.3%. Molecular characterization of hairy roots by RT-PCR analyses confirmed
their transgenic nature. In vitro conditions for apple hairy root growth and maintenance
were optimized using different mineral solutions and auxins. The liquid half-strength MS medium
with the addition of IBA at 0.025 mg L-1 was chosen for the initial stimulation of growth. For their
prolonged cultivation and maintenance, the alternation of IBA-containing and IBA-free media is
recommendable. Fast-growing lines continuously maintained in IBA-free medium were used for
further research. Potential allelochemicals including phenolic acids (chlorogenic, caffeic, syringic,
p-coumaric and ferulic), glycosilated flavonoids (phloridzin, rutin, quercitrin, isoquercitrin, kaempferol-
3-glucoside) and flavonoid aglycons (floretin, quercetin and naringenin) have been detected
by UHPLC/DAD/(+/-)HESI-MS/MS analyses in the growth medium, in which these transformed
roots were maintained for 4 weeks, as well as in the root tissue itself. The obtained hairy-root
cultures offer a complementary system for studying and validating the allelopathic potential of
apple roots.

AB  - In the previous study, phenolic acids and polyphenolic flavonoids were identified as putative
allelochemicals in apple cv. Golden Delicious hairy roots growth medium. In order to examine
their allelopathic potential, the effect of hairy root exudates on the germination and seedling
growth of the test species Arabidopsis thaliana was elucidated. Arabidopsis seeds were cultivated
in Erlenmeyer flasks containing 25 mL of liquid medium in which apple hairy roots were cultivated
for 4 weeks. The effect of apple hairy root growth medium on Arabidopsis was evaluated after 5
and 10 days of seed cultivation. Apple hairy root exudates had no significant effect on Arabidopsis
germination rate, while growth characteristics of seedlings were significantly affected both after
5 and 10 days of treatment. The roots of treated seedlings were significantly shorter (35.1%), with
lower number (74% decrement) of lateral roots compared to control after10 days of treatment.
The growth and morphology of Arabidopsis shoots and leaves have been affected too. Thus, the
shoots of treated seedlings were almost twice shorter compared to control after 5 days of treatment. At the 10th day, this distinction became more pronounced, when two fully expanded leaves
were visible in treated seedlings, while control had completely developed rosettes with six leaves.
In addition, leaves of treated seedlings were smaller and pale in colour compared to control. qPCR
expression analysis of genes involved in regulation of the cell cycle showed reduction of transcript
levels in roots of treated seedlings, with the highest expression decrease detected for CDKA1 and
CYCB2;4 cyclin.

AB  - Since the genetic transformation of the apple is strongly genotype-dependent and generally inefficient, the evaluation of factors affecting shoot regeneration are crucial for the establishment of a successful transformation process. In this report, we evaluated the effects of the β-lactam antibiotics meropenem and timentin on in vitro regeneration via de novo shoot organogenesis from leaf explants of apple cv. Golden Delicious, as well as on the growth of the Agrobacterium tumefaciens strain EHA 105, and compared them with the commonly used β-lactam cefotaxime. Also, we report for the first time the effect of hygromycin B as a selective agent in the domesticated apple, as regards shoot regeneration and shoot multiplication efficiency. We observed that cefotaxime and timentin at concentrations higher than 100 mg L-1 were sufficient to prevent Agrobacterium growth during a two-week period, while meropenem exhibited an inhibitory effect on bacterial growth at all tested concentrations (25-150 mg L-1). Cefotaxime at a concentration of 300 mg L-1 increased the number of regenerated shoots per explant (9.39) in comparison with the control (7.67). In contrast to cefotaxime, meropenem and timentin caused a decrease in shoot regeneration efficiency, but larger and more developed shoots were obtained on meropenem (25-125 mg L-1) after the same period of cultivation. Hygromycin B at a concentration of 5 mg L-1 or higher completely inhibited shoot regeneration and induced explant tissue necrosis. Therefore, the selection procedure with a final concentration of 4 mg L-1 throughout organogenesis and 10 mg L-1 for further shoot growth and multiplication is recommended for an efficient transformation process in apple cv. Golden Delicious.

AB  - Chenopodium murale L. is an invasive weed species significantly interfering with wheat crop. However, the complete nature of its allelopathic influence on crops is not yet fully understood. In the present study, the focus is made on establishing the relation between plant morphophysiological changes and oxidative stress, induced by allelopathic extract. Phytotoxic medium of C. murale hairy root clone R5 reduced the germination rate (24% less than control value) of wheat cv. Nataša seeds, as well as seedling growth, diminishing shoot and root length significantly, decreased total chlorophyll content, and induced abnormal root gravitropism. The R5 treatment caused cellular structural abnormalities, reflecting on the root and leaf cell shape and organization. These abnormalities mostly included the increased number of mitochondria and reorganization of the vacuolar compartment, changes in nucleus shape, and chloroplast organization and distribution. The most significant structural changes were observed in cell wall in the form of amoeboid protrusions and folds leading to its irregular shape. These structural alterations were accompanied by an oxidative stress in tissues of treated wheat seedlings, reflected as increased level of H2O2 and other ROS molecules, an increase of radical scavenging capacity and total phenolic content. Accordingly, the retardation of wheat seedling growth by C. murale allelochemicals may represent a consequence of complex activity involving both cell structure alteration and physiological processes.

These abnormalities mostly included the increased number of mitochondria and reorganization of the vacuolar compartment, changes in nucleus shape, and chloroplast organization and distribution. The most significant structural changes were observed in cell wall in the form of amoeboid protrusions and folds leading to its irregular shape. These structural alterations were accompanied by an oxidative stress in tissues of treated wheat seedlings, reflected as increased level of H2O2 and other ROS molecules, an increase of radical scavenging capacity and total phenolic content. Accordingly, the retardation of wheat seedling growth by C. murale allelochemicals may represent a consequence of complex activity involving both cell structure alteration and physiological processes.",

AB  - Phototropic (PT) and gravitropic (GT) bending are the two major tropic movements that determine the spatial position of potato shoots. We studied PT bending of potato plantlets grown under long-day photoperiods in several prearranged position setups providing different interactions with the GT response. Starting with the standard PT stimulation setup composed of unilateral irradiation of vertically positioned shoots, experiments were also done in antagonistic and synergistic setups and in treatments with horizontal displacement of the light source. In the standard setup, PT bending suppressed the GT bending, which could occur only if the PT stimulation was cancelled. The antagonistic position, with phototropism and gravitropism attempting to bend shoots in opposite directions, showed phototropism and gravitropism as independent bending events with the outcome varying throughout the day reflecting diurnal changes in the competence of individual tropic components. Whilst gravitropism was constant, phototropism had a marked daily fluctuation of its magnitude with a prominent morning maximum starting an hour after the dawn in the growth room and lasting for the next 6 h. When phototropism and gravitropism were aligned in a synergistic position, stimulating shoot bending in the same direction, there was little quantitative addition of their individual effects. The long period of morning PT bending maximum enabled multiple PT bending events to be conducted in succession, each one preceded by a separate lag phase. Studies of secondary PT events showed that potato plantlets can follow and adjust their shoot position in response to both vertical and horizontal movements of a light source. PT bending was reversible, since the 180° horizontal change of a blue light (BL) source position resulted in reversal of bending direction after a 20-min-long lag phase.

AB  - The effect of antibiotics hygromycin, cefotaxime and meropenem on shoot regeneration in apple cultivar “Golden Delicious” was evaluated to optimize the protocol for Agrobacterium tumefaciens-mediated genetic transformation. The careful determination of antibiotics concentration is important step to ensure efficient elimination of Agrobacterium and appropriate selection process without escapes and detrimental effect on plant regeneration. Healthy and fully expanded young leaves of in vitro grown apple shoots were cut
transversely into three pieces that were used as explants for shoot regeneration. Regeneration frequency, the
mean number of shoots per explant and the index of shoot-forming capacity were calculated after 8 weeks
of culturing on Murashige and Skoog medium containing 5 mg L-1 thidiazuron (TDZ) and 0.3 mg L-1 indole-
3-butyric acid (IBA), supplemented with hygromycin (0, 2, 4, 5, 6, 8 and 10 mg L-1), cefotaxime (0, 100, 200,
300, 400, 500 and 600 mg L-1) or meropenem (0, 25, 50, 75, 100, 125 and 150 mg L-1). Results indicated that
the highest index of shoot-forming capacity was obtained at 300 mg L-1 cefotaxime (3.67) comparing to control (2.93) and other antibiotic treatments. The increase of hygromycin concentration significantly decreased
regeneration efficiency, while at concentrations of 5 mg L-1 and higher it completely inhibited shoot regeneration. Therefore, the present study outlines the use of cefotaxime at 300 mg L-1 and a stepwise selection procedure with the final hygromycin concentration of 5 mg L-1 as a suitable system for A. tumefaciens-mediated
genetic transformation of apple cultivar “Golden Delicious”.

AB  - Goosefoot (Chenopodium murale L.) is a cosmopolitan weed species whose root produces substances
with allelopathic effects to various plant species, including agricultural ones. To investigate the
allelopathic effect of C. murale on vegetable plant collard greens (Brassica oleracea L. var. acephala),
the sterilized seeds of collard greens were treated with liquid nutrient medium in which C. murale
hairy root clone R5 was grown for 4 weeks and which contained its exudates. Results indicated that
final germination rate was not affected by R5 while the growth and development of collard greens
seedlings were significantly inhibited. The roots were more affected than shoots. Comparing to the
control, seedlings treated with R5 had reduced number of roots per seedling (27%), root length
(33%) and root fresh weight (59%). Further, R5 led to the seedlings bending, loss of chlorophyll in
the leaves, root necrosis and finally seedlings decay, indicating the ultimate lethal effect of C. murale
allelochemicals. The seedling growth inhibition was accompanied with alteration in antioxidant
enzymes activities illustrated by increased peroxidase (POD), superoxide dismutase (SOD) and
catalase (CAT) activity in shoots and emphasized CAT and decreased SOD activity in roots. The
results could be contributed to the dissemination of knowledge about allelopathic influence of C.
murale on cultivated plants and can be helpful in determining the mode of action against this weed
species to protect collard greens plants

AB  - Efficient protocols, safe from somaclonal variation, were developed for
   regeneration of Iris sibirica plants via organogenesis and somatic
   embryogenesis from leaf-base explants cultivated on Murashige and Skoog
   media supplemented with thidiazuron (TDZ, 1.0 mg/l) or
   2,4-dichlorophenoxyacetic acid (2,4-D, 1.0 mg/l). The morphogenic
   response and callus formation efficiency differed significantly between
   2,4-D (80.9\%) and TDZ (67\%) morphogenesis induction treatments. TDZ
   induced only organogenic calli, while calli obtained with 2,4-D were
   composed of three types differing in color and consistency: white,
   friable - embryogenic calli (4.5\%, 3.8 mg/explant), green, compact -
   organogenic calli (12.4\%, 48.4 mg/explants) and yellow -
   non-regenerative calli (773\%, 254.4 mg/explant). The cultivation of
   embryogenic calli on medium with 2,4-0 and Kinetin resulted in further
   development of somatic embryos (54 embryos/g of calli) which germinated
   with a frequency of 62\% after being transferred to a medium without
   plant growth regulators. Stable shoot cultures were established by
   transferring organogenic calli with shoot primordia to media with 0.1
   mg/l alpha-naphthaleneacetic acid (NAA) and 1.0 mg/l 6-benzylaminopurine
   (BA), while further cultivation on media of the same composition (TDZ or
   2,4-D) resulted in the reduced growth and rhizogenesis, respectively.
   The TDZ induction treatment resulted in higher number of shoots per
   explant (7.9) than the 2,4-0 treatment (43). After successful rooting
   and ex vitro acclimatization, plants were grown in the field and
   flowered to seed production. Flow cytometry, chromosome counting and
   random amplification of polymorphic DNA (RAPD) analysis indicated no
   evidence of genetic variation in plants regenerated via somatic
   embryogenesis or organogenesis. The results suggest that established

AB  - We investigated Chenopodium murale transgenic hairy root in vitro culture system as a new tool for allelopathic assays. Transgenic hairy roots were induced by Agrobacterium rhizogenes A4M70GUS from roots, cotyledons, leaves, and internodes of C. murale seedlings. Roots were found to be the best target explants, providing transformation efficiency of up to 11.1%. Established hairy root clones differed in their morphology and growth potential. Molecular characterization of these clones was carried out by PCR, RT-PCR and histochemical GUS analyses. No differences in rol gene expression were observed. Liquid culture system of characterized hairy root clones was maintained for over 2 years. Six hairy root clones were selected for assaying the allelopathic effect of their growth medium against germination and seedling elongation of wheat and lettuce test plants. The inhibitory potential varied depending on the hairy root clone. Some transgenic clones showed significantly higher inhibition compared to wild-type roots. These results revealed that hairy roots as an independent system synthesize some bioactive substances with allelopathic activity and exude them into the growth medium. Concentrations of caffeic, ferulic and p-coumaric acids (0.07-2.85 mu mol/L) identified by HPLC analysis in the growth media were at least 1000 times lower than the inhibitory active concentration (5 mmol/L) of pure grade phenolic acids, suggesting that they have a limited role in the allelopathic phenomena of C murale. The presented hairy root system appears to be a suitable tool for further investigation of the potential and nature of root-mediated allelopathic interference of C. murale. (C) 2012 Elsevier GmbH.

AB  - An efficient in vitro shoot regeneration method from leaf explants of apple cultivars Golden Delicious and Melrose by optimization of regeneration medium, explant type and orientation, dark pre-treatment, and gelling agent is presented. Murashige and Skoog's regeneration medium containing 22 mu M thidiazuron (TDZ) and 1.5 mu M indole-3-butyric acid (IBA) (M2 medium) was superior for regeneration as well as for subsequent shoot multiplication in both cultivars, providing regeneration frequency of 95% or higher in the best combination with other factors. Pre-incubation in the dark proved to be an essential factor for regeneration. The use of agar as a gelling agent provides satisfactory regeneration frequency compared with media gelled with Phyta-gel (TM). Leaf explants of cv. Melrose with adaxial surface in contact with M2 medium and those of cv. Golden Delicious orientated contrary regenerated the highest mean number of shoots per explant. Under optimal conditions, a maximal index of shoot-forming capacity of 11.44 and 6.30 for 'Melrose' and 'Golden Delicious', respectively, was achieved. Regenerated shoots were successfully rooted and acclimated ex vitro.
