Based on the water and sediment monitoring samples of 6 sections in the middle and lower reaches of the Hanjiang River in March and October 2014, 384 high-quality vOTUs (viral Operational Taxonomic Units) were obtained. The research showed that more than 95% of the vOTUs belonged to Caudovirales, and the top three abundance families were Myoviridae, Siphoviridae and Podoviridae. The analysis of PCoA (principal coordinates analysis) and ANOSIM (analysis of similarities) showed that the phage community structure in sediments was relatively stable, while the phage community in water was easy to change with seasons, and the phage community in water and sediments of the same basin might be connected. Hosts came from 19 phyla of 2 domains (kingdoms), and the most abundant host was Proteobacteria. 88% of the vOTUs had a single host of phylum level, while three vOTUs exhibited a broad host range across five phyla. Phages infecting hosts across domain (kingdoms) would infect Thermoproteota, and most commonly infected Bacteroidota. Compared with water, the community composition of phage hosts in sediments was more diverse. Pearson correlation analysis showed that the composition of pahges agreed with that of their microbial hosts at the phylum level.
