摘　　要：独脚金内酯(strigolactones,SLs)是一类新鉴定的能够强烈抑制植物分枝/分蘖形成的激素,在植物生长发育过程和抗逆过程中发挥重要作用。随着对SLs合成和信号途径的深入研究,鉴定了一系列可用于调控植物株型建成的基因。本文综述了独脚金内酯的发现过程、化学结构、合成途径、代谢途径、分布和运输、信号途径以及其在调控植物生长发育过程中的功能等。预测独脚金内酯在调控作物株型、抗逆、寄生等方面将成为未来的研究重点。本文为作物理想株型的建成和培育高产抗逆的新品种提供了思路和理论基础。Strigolactones(SLs) is a newly identified class of phytohormones that strongly inhibit the formation of branches/tillers in plants,and plays an important role in the process of plant growth and development and stress resistance.With the further study of SLs synthesis and signal pathway,a series of genes have been identified that can be used to regulate plant type formation.In this review,discovery process,chemical structure,synthetic pathway,metabolic pathway,distribution and transport,signaling pathway,and its function in regulating plant growth and development of SLs were reviewed.At the same time,the development of this field was prospeced,and it was believed that the regulation of plant type,resistance and parasitism by SLs would become the focus of future research.This paper provides ideas and theoretical basis for establishing ideal plant type and breeding new varieties with high yield and stress resistance in the future.
