Viral metagenomics analysis and eight novel viral genomes identified from the Dushanzi mud volcanic soil in Xinjiang, China

Abstract

Purpose: Viruses are the most abundant biological entities and play significant biological roles in marine system. However, little is known about their biodiversity in mud volcanic soil, which is salty and covered with emitting sludge. In this study, we report metagenomic analysis results of viral community composition and function from the Dushanzi mud volcanic soil (named NHS) in Xinjiang, China, and provide a comparative analysis with other environmental types. Materials and methods: We utilized metagenomes to obtain the virus data and carried out viral automatic phylogenetic and functional analyses by the metagenomics analysis server. After assembling by metaSPAdes, scaffolds were rapidl..
