Ecological Genomics of Newly Cultivated Lineages of Family Halieaceae (OM60/NOR5 clade)

초록

Cells of OM60/NOR5 clade have been detected in high abundance (>10%, sometimes) in the surface of coastal oceans, while only a small number of cultured strains from the OM60/NOR5 clade have been investigated by whole genome sequencing. Despite the limited number of cultures and genomes available, comparative genomics and physiological experimentation have shown that members of the OM60/NOR5 clade possess diverse metabolic potential, including bacteriochlorophyll-based anoxygenic phototrophy, chemoheterotrophy, and rhodopsin-based phototrophy. Recently, the novel family Halieaceae affiliated within a novel order Cellvibrionales was proposed to accommodate newly isolated marine gammaproteobacteria belonging to the OM60/NOR5 clade. Here, we report on 6 high-quality genomes of Halieaceae strains that were obtained from two different seas (Yellow Sea and East Sea, South Korea) by dilution-to-extinction culturing.
