Cyanophages are known to influence the population dynamics and community structure of cyanobacteria and thus play an important role in biogeochemical cycles in aquatic ecosystems. In this study, a novel Synechococcus phage S-H92 infecting Synechococcus sp. WH 8102 was isolated from the coastal water of the Yellow Sea. Synechococcus phage S-H92 contains a 187,320 bp genome of double-stranded DNA with a G + C content of 40.3%, 202 potential open reading frames (ORFs), and 15 tRNAs. Phylogenetic analysis and nucleotide-based intergenomic similarity suggest that Synechococcus phage S-H92 belongs to the Bristolvirus genus under the family Kyanoviridae. Homologs of the S-H92 open reading frame can be found in a variety of marine environments, as shown by the results of mapping the genome sequence of S-H92 to the Global Ocean Viromes 2.0 dataset. The presence of auxiliary metabolic genes (AMGs) related to photosynthesis, carbon metabolism, and phosphorus assimilation, as well as phylogenetic relationships based on complete genome sequences, reflect the mechanism of phage-host interaction and host-specific strategies for adaptation to environmental conditions. This study enriches the current genomic database of cyanophage and contributed to our understanding of the virus-host interactions and their adaption to the environment.
