摘要

Continental shelves are important areas for global biogeochemical cycling, yet the roles of sediment viruses in these areas remain poorly understood. Here, 48 surface sediment samples from the Chinese continental shelf were analyzed, and 12,540 viral operational taxonomic units (vOTUs) were identified. Taxonomic classification found that 93.6% of the vOTUs could not be assigned at the family level, and protein-sharing networks showed that 60.4% were singletons. Viral community structure was shaped primarily by temperature and water depth. A total of 557 auxiliary metabolic genes (AMGs) were identified, including those involved in sulfur reduction and phosphorus acquisition (Pho-family proteins). Additionally, diverse antibiotic resistance genes (ARGs) were detected, suggesting anthropogenic influence. This study reveals the diversity, ecological function, and environmental drivers of viral communities in continental shelf sediments, providing new insights into viral contributions to microbial ecology and biogeochemical processes.
