Genomic characterization of three novel Pseudomonas phages within the subfamily of Autographivirinae isolated from organic waste

Abstract

Three phages targeting Pseudomonas syringae GAW0113 have been isolated from organic waste samples: Pseudomonas phage Bertil, Misse and Strit. The phages have double-stranded DNA genomes ranging from 41342 to 41374 bp in size comprising 50 to 51 open reading frames. The three phages genomes are highly similar and genomic comparison analyses shows that they all belong to the Autographivirinae subfamily of the family Podoviridae. The phages are however only distantly related to other members of this family, and have limited gene synteny with type-phages of other genera within Autographivirinae, suggesting that the newly isolated phages could represent a new genus.
