Characterization and comparative genomic analysis of a marine Bacillus phage reveal a novel viral genus.

ABSTRACT: Bacillus pumilus exhibits substantial economic significance, with its metabolism, adaptability, and ecological functions regulated by its bacteriophages. Here, we isolated and characterized a novel temperate phage vB_BpuM-ZY1 from B. pumilus derived from mangrove sediments by mitomycin C induction. Phage vB_BpuM-ZY1 is a typical myophage, which has an icosahedral head with a diameter of 43.34 ± 2.14 nm and a long contractible tail with a length of 238.58 ± 5.18 nm. Genomic analysis indicated that vB_BpuM-ZY1 encodes genes for lysogeny control, and its life cycle may be intricately regulated by multiple mechanisms. vB_BpuM-ZY1 was predicted to employ P2-like 5'-extended-cos packaging strategy. In addition, genome-wide phylogenetic tree and proteome tree analyses indicated that
