新型植物激素独脚金内酯的研究进展

新型植物激素独脚金内酯是独脚金醇类化合物的总称,具有抑制植物分枝生长等多种重要的生物学功能。独脚金内酯具有相同的碳骨架结构,来源于类胡萝卜素生物合成途径,很可能是通过受体蛋白介导进行信号转导。目前,独脚金内酯已成为国际研究热点,但国内研究起步却较晚。为了深入了解独脚金内酯,笔者归纳了独脚金内酯分离、结构、生物学功能、生物合成及信号转导途径、分布与进化方面的最新研究进展,并探讨了其研究方向和应用前景,为独脚金内酯的深入研究提供借鉴。

Research Progress of Novel Plant Hormone Strigolactones

The novel plant hormone strigolactones was the general name for strigol-like compounds and had many important biological functions such as inhibition on plant branching. Strigolactones had the same carbon skeleton structure and came from carotenoid biosynthetic pathway. The signal transduction in strigolactones was mediated by receptor-protein. Strigolactones became a focus in international research at present, but the domestic research started relatively late. In order to deepen the understanding of strigolactones, the author concluded that the latest research progress of isolation, structure, biological function, pathway of biosynthesis and signal transduction, distribution and evolutionary about strigolactones. The research direction and application prospects about strigolactones were also discussed. This paper would provide reference for further in-depth study of strigolactones.
