Abstract:

Sterols are isoprene compounds and play an important role in the growth and development of organisms. Sterols are not only structural components of eukaryotic cell membrane,but also precursors of sterol hormone biosynthesis,which play a key role in plant cell division,embryogenesis and development,and participating in stress. In plants,the multiple functions of sterol derived brassinosteroids(BRs)in growth and development have been extensively studied. BRs as a class of plant hormone,cooperate with other hormones to play a variety of functions in plant growth and development. BRs play an important role in all aspects of plant life cycle from cell division,cell expansion,stomatal conductance and root development. In addition to these functions,BRs,as an important product of the phytosterol synthesis pathway,act as an important signal molecule responding to adversity stress and regulating plant morphogenesis. This article outlines the research progress of the related genes in the BRs synthesis pathway,and summarizes the biosynthesis of brassinolide and its research progress in regulating plant growth and development. Finally,the research prospects of brassinolide are discussed and prospected.

Key words: sterol, brassionosteroids, growth and development, adversity stress
