Diversity and ecological potentials of viruses inhabiting in the Kermadec and Diamantina trench sediments.

ABSTRACT: Viruses are the most abundant biological entities in marine ecosystems, playing an important role in biogeochemical cycling and the regulation of microbial dynamics. However, their assembly driving force, genomic evolution, and potential ecological functions in the hadal trench remain largely unknown. Here, 32 359 viral operational taxonomic units were derived from metagenomes of 40 sediment samples in the Kermadec and Diamantina trenches. High novelty and habitat-specific endemism of viruses based on the protein-sharing network analysis were demonstrated. Their auxiliary metabolic genes were involved in the biogeochemical cycles and compensatory metabolic process of the host inferring from the virus-host linkage prediction. Distinct viral community assembly in the two trenches and among d
