Bacteria can repurpose their own bacteriophage viruses (phage) to kill competing bacteria. Phage-derived elements are frequently strain specific in killing activity, although there is limited evidence that this specificity drives bacterial population dynamics. Here, we identified intact phage and derived a metapopulation of wild plant-associated Pseudomonas genomes. We discovered the most abundant viral cluster encodes remnant resembling tail called tailocin, which bacteria have co-opted...
Abstract Bacteriophages, the viruses of bacteria, are proposed to drive bacterial population dynamics, yet direct evidence their impact on natural populations is limited. Here we identified viral sequences in a metapopulation wild plant-associated Pseudomonas spp. genomes. We discovered that most abundant cluster does not encode an intact phage but instead encodes tailocin - phage-derived element bacteria use kill competitors for interbacterial warfare. Each pathogenic sp. strain carries one...
