昆虫嗅觉受体的研究进展

昆虫的嗅觉对昆虫的栖息地选择、觅食、群集、趋避、繁殖以及信息传递等行为具有重要的影响。对昆虫嗅觉机理的深入研究和嗅觉信号传导途径的完整阐述，是探索农业害虫的专一性防治的基础。嗅觉受体(olfactory receptors，Ors)是G蛋白偶联受体(G protein-coupled receptor)的一种，是嗅觉系统的关键成分。近年来嗅觉受体的研究日益受到关注。本文对昆虫嗅觉的基本过程、基因结构和表达调控特征、蛋白分子结构、生理功能、分布部位和相关配体的研究等进行了综述。

Advances in the studies of insect olfactory receptors

The olfaction has many important effects on insect behavior,including habitat choosing,food hunting,gathering,tropism,reproduction,signal communication,etc.In order to control the pest more efficiently,it is necessary to explore and understand the mechanism and signal transduction pathway of insect olfaction.Olfactory receptor(OR),as a kind of G protein-coupled receptors,is a key component of the olfactory system.In recent years,more attention is being paid to OR.In this mini-review article,we summarized the process of insect olfaction,the structure and expression regulation of receptor genes,the molecular structure,function and distribution of receptor proteins,and the study of some related ligands.
