Description
Summary:bacteria; pufM gene. Known anoxygenic photosynthetic bacteria (APB) affiliated to Gammaproteobac-teria usually use anaerobic metabolism and are restricted to oxygen-free habitats. Here, we report abundant (average of 34.5%) presence of diverse APB related to g-like Proteobacteria in oxic oceanic surface water as indicated by the pufM gene, that encodes the M subunit of the light reaction centre complex. Thus, our sequences were most likely derived from aerobic anoxygenic phototrophs (AAnP). Two genetically distinct genotypes were revealed: one was from the oligotrophic North Pacific Ocean Gyre and the other, was from the trophic East China Sea and Bering Sea. The discovery of abundant presence of novel g-like Proteobacterial pufM gene in the oxic seawater extends the functional ecotypes of AAnP.
