摘　　要：F-box蛋白在植物中广泛存在,在植物生命活动中发挥重要作用。F-box蛋白通过与Skp1、Cullin和Rbx1形成SkpCullin-F-box(SCF)蛋白复合体,参与泛素-蛋白酶途径(ubiquitin-proteasome pathway,UPP)降解生物体中的蛋白质而发挥作用。F-box蛋白广泛参与植物对干旱、盐害、温度、重金属等非生物胁迫,以及病原菌和害虫造成的生物胁迫的响应过程。主要就F-box蛋白的结构、作用途径及其在植物抗逆响应研究领域的最新进展和存在的问题进行综述,旨在为深入研究F-box蛋白增强植物抗逆性的机制提供参考。F-box protein exists widely and plays an important role in plants.The F-box protein participates in the UPP(ubiquitinproteasome pathway)to degrade proteins in organisms through synthesizing with Skp1,Cullin,Rbx1 to form Skp-Cullin-F-box(SCF)protein complex.The F-box protein is involved in the response process of plants to abiotic stress such as drought,salt,temperature and heavy metals,as well as biotic stress caused by pathogens and pests.This paper mainly reviewed the structure,action pathway,the latest progress and existing issues of F-box protein in the field of plant stress response,so as to provide reference for further study on the mechanism of F-box protein enhancing plant stress resistance.
