Abstract
Here, we report the genome sequence of a double-stranded DNA siphovirus, vB_Pae_LC3I3 infective for P. aeruginosa PA14. Phage vB_Pae_LC3I3 was identified as a linear double-stranded DNA phage of 49,926 bp with 59% G+C content. The vB_Pae_LC3I3 genome contains 78 open reading frames, and the function of 22 ORFs can be predicted. Genome analysis confirmed the lysogenic nature of this phage, which encodes the typical lysogen-related integrase and CI/Cro regulator. One-step growth curve revealed that the latent period of phage vB_Pae_LC3I3 lasted for 30 min. And vB_Pae_LC3I3 showed good temperature stability and pH stability. Based on electron microscopy, phylogenetic, and comparative genomic analyses, this novel Pseudomonas temperate phage represents a novel unassigned siphoviruses cluster. The study of phage vB_Pae_LC3I3 will provide basic information for further research on treatment of P. aeruginosa infections.
