细菌在动物体内的内生共生是一个重要的生物学研究课题。对内生共生的研究不仅对了解动物宿主的生长繁殖具有重要意义，而且对生命起源和进化的研究也具有重要意义。内共生细菌--棉铃虫(Buchnera Aphidicola)在营养和发育上都是必不可少的。由于这种必然关系，蚜虫-布氏菌模型是研究共生中许多重要理论问题的理想模型。本文综述了布氏菌的基本生物学特征、蚜虫与布氏菌之间的进化关系、布氏菌在共生联合中的作用以及布氏菌的功能基因组学，并指出了一些值得关注的科学问题。
Endosymbiosis of bacteria within animals is a major research topic in biology.Studies on endosymbiosis are important not only for understanding the growth and reproduction of animal hosts,but also for investigating of the origin and evolution of life.Aphids harbor obligatory endosymbiotic bacteria,Buchnera aphidicola,which are nutritionally and developmentally indispensable to them.Due to this obligate relationship,the aphid-Buchnera model is ideal for investigating many significant theoretical issues in symbiosis.This paper reviews research on the basic biological characteristics of Buchnera,evolutionary relationship between aphids and Buchnera,the roles of Buchnera in symbiotic association as well as functional genomics of Buchnera.We then highlight some scientific questions worthy of concern in the future.
