Genomic Analysis Reveals Adaptation of Vibrio campbellii to the Hadal Ocean.

ABSTRACT: The genus Vibrio is characterized by high metabolic flexibility and genome plasticity and is widely distributed in the ocean from euphotic layers to deep-sea environments. The relationship between genome features and environmental adaptation strategies of Vibrio has been extensively investigated in coastal environments, yet very little is known about their survival strategies in oligotrophic deep-sea. In this study, we compared genomes of five Vibrio campbellii strains isolated from the Mariana and Yap Trenches at different water depths, including two epipelagic strains and three hadopelagic strains, to identify genomic characteristics that facilitate survival in the deep sea. Genome streamlining is found in pelagic strains, such as smaller genome sizes, lower G+C contents, a
