摘要
节肢动物门是动物界最大的门,占整个动物种数的80%,全世界约有120万现存种。节肢动物在生长发育过程中会感染多种微生物,这些微生物会与其形成协同进化和互利共生的关系。内共生细菌是一类广泛分布于节肢动物体内的共生微生物,能够进行垂直传播和水平传播,对宿主的生长发育、生殖代谢、适应性、免疫功能和进化等诸多方面均具有重要的作用。目前,随着现代分子生物学理论和技术的发展,节肢动物内共生细菌相关研究主要集中在对其宿主的生殖调控功能、与其宿主、宿主寄主植物以及其宿主体内微生物和宿主天敌间互作关系等方面。因此,利用内共生细菌对昆虫种群动态的生殖调控功能,阻断热带蚊虫带来的疾病或植物病害的传播并对宿主昆虫进行种群压制或种群替换,可达到防控害虫的目的。本文从节肢动物内共生细菌的传播方式、对其宿主生物学效应以及内共生细菌与其宿主、宿主寄主植物、宿主天敌和宿主体内微生物互作关系等多方面进行概述,并对内共生细菌今后研究方向进行展望,以期为生物进化、物种形成和种群压制提供参考。
Arthropoda is the largest phylum in the animal kingdom,accounting for 80%of the whole animal kingdom.There are about 1.2 million existing species in the world.Arthropoda can be infected by various microorganisms during the process of growth and development,which subsequently form a co-evolutionary and mutually beneficial symbiotic relationship with endophytic microorganisms.Endosymbiotic bacteria are a kind of symbiotic microorganisms widely distributed in arthropods,which are able to spread vertically and horizontally.Endosymbiotic bacteria play an important role in many aspects of host insects,such as the growth,development,reproductive metabolism,adaptability,immune function and evolution.At present,research concerning the arthropod symbiotic bacteria mainly focuses on the reproductive regulation function of host insects,the interaction between host insects,host plants of hosts,microorganism in host insects and their natural enemies with the development of modern molecular biology theory and technology.Therefore,blocking the spread of diseases caused by tropical mosquitoes or plant diseases and inhibited or replaced host insects through the reproductive regulation function of endophytic bacteria on insect population dynamics can be used to control pests.In this review,we summarized the spread mode of symbiotic bacteria in arthropods,the biological effects on hosts insects,and the interaction between symbiotic bacteria and hosts insects,host plants of hosts insects,host natural enemies and microorganisms in hosts insects,and then prospected the future research direction of symbiotic bacteria.We expected to provide reference for biological evolution,species formation and population suppression.
