Abstract

A virulent halovirus QHHSV-1 which lyses Halomonas ventosae QH52-2 originating from the Qiaohou salt mine in Yunnan, Southwest China was characterized. The complete genome of QHHSV-1 is composed of a circular double-stranded DNA of 37,270 base pairs in length, with 66.8% G+C content and 69 putative open reading frames (ORFs), which were classified into five functional groups, including morphogenesis, replication/regulation, packaging, lysis and lysogeny. A putative Cro repressor gene and an integrase gene were found in the genome, showing that QHHSV-1 may utilize a lambda-like repression system under unfavorable conditions. QHHSV-1 is the first report of the whole genome sequence of the virulent Halomonas phage belonging to the family Siphoviridae.
