N2 - Two novel P. protegens bacteriophages PseuP_222 and Pseu_224 and their host P. protegens CEMTC 4060 were isolated from the same sample (Inya river, Siberia). Both phages have siphovirus morphology and belong to lambdoid phages. Comparative genome analysis revealed a low nucleotide and amino acid sequence similarity of PseuP_222 and PseuP_224 between themselves, and between them and other lambdoid phages. Bioinformatics analysis indicated that PseuP_222 and PseuP_224 are members of a genetically diverse group of phages of environmental Pseudomonas spp.; this group is distant from a large group of P. aeruginosa phages. In phylogenetic trees, the positioning of the terminase large subunits, major capsid proteins, tail tape measure proteins, and CI-like repressors of PseuP_222 and PseuP_224 were remote and changed relative to those of the Escherichia lambda phage and lambdoid phages of Pseudomonas spp. However, the nucleoid-associated protein NdpA/YejK and P5-like structural protein from both phages showed high similarity and were not found in lambda phage and other lambdoid phages of Pseudomonas spp. Substantial divergences of the PseuP_222 and PseuP_224 genomes and proteomes indicated that the evolutionary history of these phages was mostly independent and they probably began to use one host only recently.
