油菜素内酯生物合成与功能的研究进展

Advances on Brassinosteroid Biosynthesis and Functions

植物激素油菜素内酯广泛调节植物的生长发育及对外界环境因子变化的反应,在作物上的应用也已引起人们的广泛兴趣。通过遗传学等手段对相关突变体及功能基因的研究为其生物合成与功能研究提供了基础。本文总结了油菜素内酯在植物各组织内的分布、生物合成、相关合成突变体及其编码基因的性质、生理功能以及与其它激素间的相互作用等。

Plant hormone brassinosteroid （BR） acts as an important regulator in plant growth and development, and responses to environmental stimuli. BR also regulates the agritraits of many crops. Analyses on mutant phenotypes and gene functions provide the information on BR biosynthesis and physiological roles. This review focuses on the BR recent progresses of BR biosynthesis and metabolism, the underlying signaling pathways, and further the interplay with other hormones.
