“…Such conditions occur on HMs-polluted areas where not only excess amount of HMs, but also high insolation, water deficiency and strong winds occurred (Wierzbicka and Panufnik 1998). Plants from sunny and dry sites are usually characterized by greater leaf thickness than plants from other habitats (Karnaukhova 2016). Anatomical adaptations to minimize water loss were also shown in the present research.…”

“…Taking into account that leaf structure and functioning reflect its essential role in plant growth and development, their modifications might help to understand plant adaptations to stressful environmental conditions (Karnaukhova 2016). Our research revealed that leaves of S. vulgaris taken from the CAL population presented a distinct anatomical pattern compared to leaves of SER and NM specimens.…”

“…One of the most pronounced differences was concerned with the clearly developed layers of palisade parenchyma. An intensive development of this tissue indicates the adaptation mainly to high insolation and protects inside parts of leaves from unfavorable light influence (Karnaukhova 2016). Such conditions occur on HMs-polluted areas where not only excess amount of HMs, but also high insolation, water deficiency and strong winds occurred (Wierzbicka and Panufnik 1998).…”

Main conclusion Results provide significant comparison of leaf anatomy, pigment content, antioxidant response and phenolic profile between individuals from miscellaneous populations and describe unified cultivation protocols for further research on stress biology.The plant communities growing on heavy metal-polluted areas have attracted considerable attention due to their unique ability to tolerate enormous amounts of toxic ions. Three ecotypes of Silene vulgaris representing calamine (CAL), serpentine (SER) and non-metallicolous (NM) populations were evaluated to reveal specific adaptation traits to harsh environment. CAL leaves presented a distinct anatomical pattern compared to leaves of SER and NM plants, pointing to their xeromorphic adaptation. These differences were accompanied by divergent accumulation and composition of photosynthetic pigments as well as antioxidant enzyme activity. In CAL ecotype, the mechanism of reactive oxygen species scavenging is based on the joint action of superoxide dismutase and catalase, but in SER ecotype on superoxide dismutase and guaiacol-type peroxidase. On the contrary, the concentration of phenylpropanoids and flavonols in the ecotypes was unchanged, implying the existence of similar pathways of their synthesis/degradation functioning in CAL and SER populations. The tested specimens showed genetic variation (atpA/MspI marker). Based on diversification of S. vulgaris populations, we focused on the elaboration of similar in vitro conditions for synchronous cultivation of various ecotypes. The most balanced shoot culture growth was obtained on MS medium containing 0.1 mg l −1 NAA and 0.25 mg l −1 BA, while the most abundant callogenesis was observed on MS medium enriched with 0.5 mg l −1 NAA and 5.0 mg l −1 BA. For the first time, unified in vitro protocols were described for metallophytes providing the opportunity to conduct basic and applied research on stress biology and tolerance mechanisms under freely controlled conditions.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…Наиболее значимые структурные и количественные перестройки, происходящие в анатомическом строении листа в высотном градиенте, выявились в результате изучения высокогорных видов H. theinum и H. consanguineum (Karnaukhova, 2016. Выяснилось, что экологическая адаптация этих видов к различным условиям горных систем Южной Сибири происходит преимущественно на основе изменчивости количественных показателей соотношения палисадной и губчатой паренхимы мезофилла листа, числа устьиц и размеров клеток палисады, эпидермиса и идиобластов.…”

“…То есть, чем больше диапазон пластичности вида, тем большие изменения претерпевают бочковидные идиобласты, а сеть многолопастных клеток в губчатой ткани становится более плотной. Суммарный объем всех водозапасающих структур на объем листочка может быть довольно значителен (Karnaukhova, 2016). На примере H. theinum мы подсчитали долю водозапасающих структур от объема ткани, в которой они расположены.…”

Аннотация. По анатомическим особенностям строения листовой пластинки прослежена адаптация видов секции Gamotion Basin. рода Hedysarum L. к различным условиям произрастания в Южной Сибири. На примере H. consanguineum DC. и H. theinum Krasnob. показано, что в высотном градиенте местообитаний гелиоморфные черты нарастают: уменьшаются размеры растений и листа, увеличиваются толщина листовой пластинки, слойность палисадного мезофилла, высота палисадных и эпидермальных клеток, число устьиц и общий объем идиобластов. Выявлено, что анатомическое строение листа видов секции Gamotion, занимающих разные экологические ниши в горах и межгорных котловинах Южной Сибири, претерпевало сходные изменения в процессе приспособления к современным условиям произрастания. Растения лесного пояса H. neglectum Ledeb. и предгорно-равнинного H. alpinum L. в более сухих местообитаниях несут такие же изменения, как и высокогорные виды в высотном градиенте местообитаний. Увеличение толщины и объема листовой пластинки, общего объема идиобластов, числа рядов и высоты палисадных клеток в строении листа у видов секции Gamotion рода Hedysarum рассматриваются как важные биологические приспособления к экстремальным условиям произрастания Южной Сибири.
