油菜素内酯生物合成途径的研究进展

Progress in Biosynthetic Pathways of Brassinosteroids

油菜素内酯(BRs)在植物的生长发育过程中具有重要作用。该文首先综述了油菜素甾醇的结构及其生物合成途径的研究方法。之后,介绍了其化学及生物活性的检测方法。最后,详细介绍了BR生物合成的早期和晚期C-6氧化途径及早期C-22和C-23羟化与合成途径的调控,并阐述了近年来植物油菜素内酯生物合成缺失突变体及其合成酶等方面的研究进展。

Brassinosteroids（BRs） play an important role in the progress of plant growth and development. This paper introduces the structure of BRs and how to study the biosynthetic pathway, then describes methods for biological and chemical detection. Finally, we detail the early C-6 oxidation pathway, the late C-6 oxidation pathway and the early C-22, C-23 hydroxylation pathway, their regulation and progress in the identification of BR-deficient mutants and enzymes for BR biosynthesis.
