The Regulation of Brassinolide Biosynthesis and Physiological Effects in Grape Berries
Brassinolide is an important plant hormone regulating plant growth and development,promoting cell division and elongation,photosynthesis and respiration,photomorphogenesis,stress resistance improvement,tran-spiration reduction and make a very important contribution to the improvement of grape fruit yield and quality.In this study,key enzymes and influencing factors in brassinolide biosynthetic pathway and the effects of brassino-lides on grape fruit yield and quality were reviewed,the physiological impacts of brassinolide on plant photosyn-thesis,respiration,transpiration,and photomorphogenesis were also summarized.Meanwhile,the interaction net-work between brassinolide and other plant endogenous hormones was reviewed,opinions that future research di-rection should be focused on the synthesis of related transcription factors and interaction mechanism between brassinolides and other plant hormones as well as research and development of new efficient brassinolides plant regulators were put forward.
