Aerobic anoxygenic phototrophic bacteria (AAnPs) were previously proposed to account for up to 11% of marine bacterioplankton and to potentially have great ecological importance in the world's oceans. Our data show that previously used primers based on the M subunit of anoxygenic photosynthetic reaction center genes (pufM) do not comprehensively identify the diversity of AAnPs in the ocean. We have designed and tested a new set of pufM-specific primers and revealed several new AAnP variants in environmental DNA samples and genomic libraries.
需氧不产氧光合细菌(AAnPs)此前被认为在海洋浮游细菌中占比高达11%,并可能在全球海洋中具有重大生态意义。我们的数据表明,先前基于不产氧光合反应中心基因(pufM)的M亚基所使用的引物并不能全面识别海洋中AAnPs的多样性。我们设计并测试了一组新的pufM特异性引物,并在环境DNA样本和基因组文库中发现了几种新的AAnP变体。
