Physiological role of brassinolide in the light development of Arabidopsis thaliana seedling

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 - skoto- or photomorphogenesis and endogenous level of brassinosteroids has been shown.
