不产氧光合细菌的分类学进展

Current taxonomy of anoxygenic phototrophic bacteria——A review

不产氧光合细菌(APB)一直是研究生命起源与进化、光合作用和固氮机理的良好模式生物。近年来,APB资源研究发展迅速,不断发现新的物种、模式种及特殊功能物种,不断提出新的分类单元,APB分类系统发生了较大变化,同时引起了一定混乱。本文对不产氧光合细菌定义、分类系统和分类指征最新进展进行了系统述评,对分类系统中存在的问题和发展趋势也进行了评述。

Anoxygenic phototrophic bacteria （APB） are good model organisms used to study the origin and evolution of life, photosynthesis and nitrogen fixation mechanism. With increasingly available genetic information and establishment of sequencing techniques for nucleic acid, more attention has been paid to exploration of APB resources from various habitats especially extremely environment. The pace of new species description has been increasing in recent years, and some new taxonomic taxa are also proposed, therefore, it is necessary to redefine APB and provide the newest taxonomic system of APB. We reviewed the problems and prospect about taxonomy of anoxygenic phototrophic bacteria. The definition, situation of the taxonomy, characteristics for APB identification are noted and commented from the discovery of APB up to now.
