c Pectobacterium carotovorum subsp. carotovorum, a member of the Enterobacteriaceae family, is an important plant-pathogenic bacterium causing significant economic losses worldwide. P. carotovorum subsp. carotovorum bacteriophage My1 was isolated from a soil sample. Its genome was completely sequenced and analyzed for the development of an effective biological control agent. Sequence and morphological analyses revealed that phage My1 is a T5-like bacteriophage and belongs to the family Siphoviridae. To date, there is no report of a Pectobacterium-targeting siphovirus genome sequence. Here, we announce the complete genome sequence of phage My1 and report the results of our analysis.
c Pectobacterium carotovorum subsp. carotovorum is a phytopathogen causing soft rot disease on diverse plant species. To control this plant pathogen, P. carotovorum subsp. carotovorum-targeting bacteriophage PP1 was isolated and its genome was completely sequenced to develop a novel biocontrol agent. Interestingly, the 44,400-bp genome sequence does not encode any gene involved in the formation of lysogen, suggesting that this phage may be very useful as a biocontrol agent because it does not make lysogen after host infection. This is the first report on the complete genome sequence of the P. carotovorum subsp. carotovorum-targeting bacteriophage, and it will enhance our understanding of the interaction between phytopathogens and their targeting bacteriophages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
