Two novel dsDNA bacteriophages named Pectobacterium virus CB251 (PcCB251) and Pectobacterium virus CB7V (PcCB7V) targeting plant pathogen Pectobacterium 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 genus Berlinvirus, family Autographiviridae. 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 genus Certrevirus, subfamily Vequintavirinae. 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.

两种新型 dsDNA 噬菌体名为Pectobacterium CB251 (PcCB251) 和Pectobacterium CB7V (PcCB7V) 靶向植物病原体Pectobacterium parmentieri已被分离和测序。PcCB251 基因组由 40,557 bp 组成，G+C 含量为 48.6%，在单链上包含 47 个预测基因。噬菌体被归类在属Berlinvirus，家庭Autographiviridae。PcCB7V 噬菌体具有 146,054 bp 的环状 dsDNA 基因组，G+C 含量为 50.4%，两条链上都包含 269 个预测的蛋白质基因和 13 个 tRNA 基因。该PcCB7V噬菌体可以属分类Certrevirus，亚科Vequintavirinae. 两种新型噬菌体的宿主范围都很窄，但它们扩展了基于噬菌体控制导致马铃薯软腐病的果胶分解菌的候选者名单。
