Lytic properties and genomic analysis of bacteriophage Brt_Psa3, targeting Pseudomonas syringae pv. actinidiae.

ABSTRACT: Pseudomonas syringae pv. actinidiae (Psa) is the causative agent of bacterial canker in kiwifruit (Actinidia spp.). Psa biovar 3 is the most prevalent and virulent, causing frequent and severe outbreaks worldwide. While current treatments have low efficacy, bacteriophages emerge as possible environmentally safe alternative biocontrol agents. In this study, bacteriophage Brt_Psa3 was isolated from the soil of a kiwifruit orchard in Portugal. Morphologically, Brt_Psa3 forms clear plaques and has a Podoviral morphotype. The bacteriophage exhibited broad lytic activity against several plant-pathogenic Pseudomonas strains, including Psa isolates. The isolated bacteriophage has a latent period of 100 min, a burst size of 143 particles/cell, and demonstrates stability at different temperatures an
