马铃薯Y病毒属病毒外壳蛋白功能

Functional Characterization of Potyvirus-encoded Coat Protein

Potyvirus属于马铃薯Y病毒科(Potyviridae),是最大的植物病毒属,给农业生产造成严重的经济损失。外壳蛋白(Coat Protein简称CP)是Potyvirus属病毒中相对较稳定、功能较复杂的编码蛋白,涉及到病毒传播、运动、抗性及症状表达。本文详细分析了外壳蛋白的功能,包括参与病毒的蚜传、参与病毒的长距离运动和胞间运动、参与植物病毒病防治和参与病毒症状表达。对病毒蛋白功能的研究为该属病毒的研究发展提供重要的理论基础,对Potyvirus侵染机制及抗病机理研究具有指导价值。

Potyvirus belonging to family Potyviridae,is the largest plant virus family,which can be responsible for severe economic losses to agriculture world-wide.Coat proteins of potyviruses show relatively steady in compared to other proteins among potyviruses and multi-functional,related with the transmission of the virus,movement,resistance and symptom expression.This paper analyzed the functions of coat protein,including participation in aphid transmission of virus,long-distance and intercellular movement of virus,participation in plant virus disease control and virus symptoms expression.The functional characterization of potyvirus-encoded proteins supported the understanding of potyviruses,and promoted the research of potyviruses infectious and resistant mechanisms.
