蝗虫嗅觉相关蛋白及其功能研究进展

Research Progress on Olfactory-Related Proteins and Their Functions in Grasshoppers

嗅觉在昆虫生命活动中起着重要的作用,气味结合蛋白(Odorant Binding Proteins,OBPs)和化学感受蛋白(Chemosensory Proteins,CSPs)在昆虫的嗅觉系统中发挥重要作用。近年来随着基因组学和转录组学的快速发展,蝗虫OBP和CSP基因陆续被鉴定出来,部分OBP基因的功能也逐步被证实。本文针对蝗虫OBPs和CSPs的种类、结构特征、表达分布、三维结构以及生理功能等方面进行概述,为更多昆虫OBP基因的鉴定及其功能研究提供参考,也为进一步揭示昆虫-环境间的化学通讯机理以及开辟新的害虫防治策略奠定基础。

Olfaction plays an important role in the life activities of insects.Odorant Binding Proteins(OBPs)and Chemosensory Proteins(CSPs)play an important role in the olfactory system of insects.In recent years,with the rapid development of genomics and transcriptomics,locust OBP and CSP genes of grasshoppers have been successively identified,and the functions of some OBP genes have been gradually confirmed.In this article,the species,structural characteristics,expression distribution,there-dimensional structure and physiological function of OBPs and CSPs of grasshoppers were summarized,which provided a reference for the identification and functional study of more insect OBP genes,and laid a foundation for further revealing the chemical communication mechanism between insects and environment and opening up new pest control strategies.
