| contents | Comparative genomic analyses of aerobic planctomycetes isolated from the deep sea and the ocean surface. Øvreås, Lise Kallscheuer, Nicolai Calisto, Rita Bordin, Nicola Storesund, Julia E Jogler, Christian Devos, Damien Lage, Olga Phylogeny Genome, Bacterial Seawater Pacific Ocean Hydrothermal Vents Genomics Oceans and Seas Ecosystem On the deep and dark seafloor, a cryptic and yet untapped microbial diversity flourishes around hydrothermal vent systems. This remote environment of difficult accessibility exhibits extreme conditions, including high pressure, steep temperature- and redox gradients, limited availability of oxygen and complete darkness. In this study, we analysed the genomes of three aerobic strains belonging to the phylum Planctomycetota that were isolated from two deep-sea iron- rich hydroxide deposits with low temperature diffusive vents. The vents are located in the Arctic and Pacific Ocean at a depth of 600 and 1,734 m below sea level, respectively. The isolated strains Pr1d, K2D and TBK1r were analyzed with a focus on genome-encoded features that allow phenotypical adaptations to the low temperature iron-rich deep-sea environment. The comparison with genomes of closely related surface-inhabiting counterparts indicates that the deep-sea isolates do not differ significantly from members of the phylum Planctomycetota inhabiting other habitats, such as macroalgae biofilms and the ocean surface waters. Despite inhabiting extreme environments, our "deep and dark"-strains revealed a mostly non-extreme genome biology. |
