Исследовали активность гистонацетилтрансферазы (ГАТ), гистондеацетилазы (ГДА), содержание активных форм кислорода (АФК), антиоксидантную активность аскорбатпероксидазы (АП), каталазы (Кат) и тиоредоксинов (ТР) в клетках каллюсной культуры А. thaliana на начальных этапах острого осмотического стресса. Установлено, что при действии стресса повышались активности ГАТ, ГДА, содержание АФК, в частности Н2О2, активности АП, Кат и ТР. Полученные результаты обсуждаются в аспекте регуляции экспрессии генома и роли редокс-сигналинга при формировании стресс-реакции клеток растений.
Ключевые слова: Arabidopsis thaliana, каллюсная культура, гистонацетилтрансфераза, гистондеацетилаза, активные формы кислорода, аскорбатпероксидаза, каталаза, тиоредоксин, осмотический стресс
