摘　　要：嗅觉在哺乳动物的日常活动中发挥重要作用。嗅觉是一个复杂的生物学过程,挥发性气味分子与专门存在于嗅觉上皮细胞的嗅觉受体(OR)特异性结合,以发挥嗅觉的生物学功能。OR与气味物质的结合向大脑传递关于食物位置、潜在配偶、捕食者和有害物质的信号。嗅觉感受器也存在于鼻腔以外的器官中,其与动物内环境中的营养物质和代谢产物等分子结合,从而引发生理反应。文章综述了OR基因的结构、分布、多态性、功能、相关的信号通路以及嗅觉在动物采食中的作用,为研究嗅觉在动物采食中的作用提供参考。The sense of smell plays an important role in daily activities of mammals.Olfaction is a complex biological process.Volatile odor molecules specifically bind to olfactory receptors(OR)present in olfactory epithelial cells to exert the biological function of olfaction.OR in the air through olfactory receptors and sends signals to the brain about the location of food,potential mates,predators and harmful substances.Detects olfactory substances also found in organs other than the nasal cavity,bind to molecules such as nutrients and metabolites in the animal's internal environment to trigger a physiological response.The article mainly focuses on the structure,distribution,polymorphism,function,related signaling pathways of OR genes and the role of smell in animal feeding,in order to provide reference for studying the role of olfactory in animal feeding.
