Complete genome sequences of novel Berlinvirus and novel Certrevirus lytic for Pectobacterium sp. causing soft rot and black leg disease of potato

AbstractTwo novel dsDNA bacteriophages namedPectobacterium virus CB251 (PcCB251) andPectobacterium virus CB7V (PcCB7V) targeting plant pathogenPectobacterium parmentieri have been isolated and sequenced. The PcCB251 genome consists of 40,557  bp with G+C content of 48.6% and contains 47 predicted genes on a single strand. The phage is classified in genusBerlinvirus, familyAutographiviridae. The PcCB7V phage has a circular dsDNA genome of 146,054  bp with G+C content of 50.4% and contains 269 predicted protein genes on both strands and 13 tRNA genes. The PcCB7V phage can be classified in genusCertrevirus, subfamilyVequintavirinae. Both novel bacteriophages have narrow host ranges, but they extend the list of candidates for phage-based control of pectolytic bacteria causing soft rot disease of potato.
