水稻二化螟热激蛋白的研究进展

Research progresses in the heat shock proteins of Chilo suppressalis

水稻二化螟Chilo suppressalis(Walker)是水稻上的主要害虫之一,近年来在部分地区发生为害逐渐加重。热激蛋白是一类胁迫蛋白,在细胞生长、发育、分化、基因转录等功能方面具有重要的作用。本文综述了二化螟热激蛋白的研究进展。目前,已在二化螟体内鉴定出11种热激蛋白,它们分别属于热激蛋白90家族、热激蛋白70家族、热激蛋白60家族和小分子量热激蛋白家族。这些热激蛋白在二化螟生长发育中的调节作用也各不相同;同时,热激蛋白(Cshsp90,Cshsp70和Cshsp60)还与水稻二化螟的滞育有着紧密的联系。不同的热激蛋白对温度的响应大体可以分为三种类型:对高低温都有响应型、对低温响应型和对温度不响应型。最后,分析了二化螟热激蛋白研究过程中存在的问题,提出了该研究领域的展望。

The rice stem borer,Chilo suppressalis(Walker),is one of most important rice pests.In recent years,C.suppressalis have caused more and more damages.Heat shock proteins belong to stress proteins,which play very important roles in the development,differentiation,gene transcription of cells.In this review,the progresses in the heat shock proteins of C.suppressalis were summarized.To date,11 heat shock proteins have been identified from C.suppressalis,belonging to heat shock protein 90,heat shock protein 70,heat shock protein 60,and small heat shock protein family.They played different roles in the development of C.suppressalis.Moreover,heat shock proteins(Cshsp90,Cshsp70 and Cshsp60)are also closely related to the diapause of C.suppressalis.In general,the responses of heat shock proteins to temperature can be divided into three types:response to both heat and cold stress,response to cold stress only and no response to temperature.Last,the problems in the study of heat shock proteins of C.suppressalis were analyzed,and the prospects for the future study was exhibited.
