Characterization of two novel bacteriophages (PSV6 and PSV3) as biocontrol agents against <i>Pseudomonas syringae</i>.

ABSTRACT: Pseudomonas syringae is a prevalent plant-pathogenic bacterium. Conventional control strategies, such as fungicides, copper-based compounds, and antibiotics, often result in elevated environmental toxicity and promote the emergence of bacterial resistance. Consequently, bacteriophage-based biocontrol has garnered considerable attention as an eco-friendly alternative. In this study, two novel bacteriophages, PSV6 and PSV3, were isolated from wastewater using Pseudomonas syringae pv. syringae (Pss) as the host strain. Transmission electron microscopy and whole-genome phylogenetic analyses indicated that both phages belong to the class Caudoviricetes, with PSV6 classified within Autotranscriptaviridae and PSV3 within Jondennisvirinae. The one-step gro
