Физиологическая роль брассинолида в световом развитии проростков Arabidopsis thaliana

Физиологическая роль брассинолида в световом развитии проростков Arabidopsis thaliana

Abstract

В статье рассказывается о проведении исследований регуляторной роли наиболее активного представителя семейства брассиностероидов брассинолида в развитии проростков в темноте. Изучены ростовые показатели и состав фотосинтетических пигментов проростков в зависимости от условий освещения. В качестве объекта исследований были выбраны растения арабидопсиса Arabidopsis thaliana, отличающиеся по эндогенному уровню брассиностероидов родительская линия экотипа Columbia и его мутант det2 с нарушенным синтезом брассинолида. Отмечена зависимость ростовых показателей проростков от концентрации брассинолида. Показана физиологическая активность зеленого света, наряду с синим, в регуляции развития растений A. thaliana на начальных этапах онтогенеза. Высказано предположение о тесной связи между выбором определенной программы развития растений скотоморфогенезом или фотоморфогенезом и эндогенным уровнем брассиностероидов.

The regulatory role of more active brassinosteroids brassinolide in seedling development in darkness was studied. The growth parameters and photosynthetic pigment content of Arabidopsis thaliana seedlings under differ light conditions were investigated. The plant model to study regulatory role of selective light and brassinosteroids are Arabidopsis thaliana. A. thaliana ecotype Columbia (Col) and det2 mutant with disturbed synthesis of brassinolide were used. The plant grow parameters depending on the brassinolide concentration. Physiological activity of green light also blue light in the regulation of Arabidopsis seedling development was noted. The interaction between plant development program skotoor photomorphogenesis and endogenous level of brassinosteroids has been shown.
