Mangroves are ecologically and economically important forests of the tropics. As one most carbon-rich biomes, mangroves account for 11% total input terrestrial carbon into oceans. Although viruses considered to significantly influence local global biogeochemical cycles, little information is available regarding community structure, genetic diversity ecological roles in mangrove ecosystems.Here, we utilised viral metagenomics sequencing virome-specific bioinformatics tools study communities six soil samples collected from different habitats Southern China.Mangrove were found be largely uncharacterised. Phylogenetic analyses major groups demonstrated extensive previously unknown clades suggested that possibly comprise evolutionarily close genotypes. Comparative analysis genotypes revealed viromes mainly affected by marine waters, with less coming freshwaters. Notably, identified abundant auxiliary carbohydrate-active enzyme (CAZyme) genes viruses, which participate biolysis complex polysaccharides, soils organism debris. Host prediction results showed CAZyme diverse probably widespread phages infecting bacteria phyla.Our directly manipulate cycling participating biomass recycling providing knowledge essential revealing ecosystems.
