Because of recent advances in omics methodologies, knowledge of chlorophototrophy (i.e., chlorophyll-based phototrophy) in bacteria has rapidly increased. Chlorophototrophs currently are known to occur in seven bacterial phyla: Cyanobacteria, Proteobacteria, Chlorobi, Chloroflexi, Firmicutes, Acidobacteria, and Gemmatimonadetes. Other organisms that can produce chlorophylls and photochemical reaction centers may still be undiscovered. Here we summarize the current status of the taxonomy and phylogeny of chlorophototrophic bacteria as revealed by genomic methods. In specific cases, we briefly describe important ecophysiological and metabolic insights that have been gained from the application of genomic methods to these bacteria. In the 20 years since the completion of the Synechocystis sp. PCC 6803 genome in 1996, approximately 1,100 genomes have been sequenced, which represents nearly the complete diversity of known chlorophototrophic bacteria. These data are leading to new insights into many important processes, including photosynthesis, nitrogen and carbon fixation, cellular differentiation and development, symbiosis, and ecosystem functionality.

组学时代揭示的氯光合细菌的多样性

由于组学方法学的最新进展，细菌中叶绿素光养（即基于叶绿素的光养）的知识迅速增加。目前已知氯光合生物存在于七种细菌门中：蓝藻门、变形菌门、绿藻门、绿屈菌门、厚壁菌门、酸杆菌门和 Gemmatimonadetes。其他能够产生叶绿素和光化学反应中心的生物可能仍未被发现。在这里，我们总结了基因组方法所揭示的氯光合细菌的分类学和系统发育的现状。在特定情况下，我们简要描述了从将基因组方法应用于这些细菌中获得的重要生态生理学和代谢见解。自集胞藻完成以来的 20 年里。1996 年的 PCC 6803 基因组，大约 1，已经对 100 个基因组进行了测序，这几乎代表了已知氯光合细菌的完整多样性。这些数据使人们对许多重要过程有了新的认识，包括光合作用、固氮和固碳、细胞分化和发育、共生和生态系统功能。
