Xanthomonas euvesicatoria-Specific Bacteriophage BsXeu269p/3 Reduces the Spread of Bacterial Spot Disease in Pepper Plants

The present study was focused on the pathosystem pepper plants (Capsicum annuum L.)-phytopathogenic bacterium X. euvesicatoria (wild strain 269p)-bacteriophage BsXeu269p/3 and possibility of bacteriophage-mediated biocontrol disease. Two new model systems were designed for monitoring effect phage treatment infectious process in vivo. spread bacteriophage pathogen monitored by qPCR. A pair primers detection via qPCR designed, as well probes TaqMan epiphytic bacterial population potential bacteriolytic vivo observed SEM. An aerosol-mediated transmission system demonstrated that with reduced amount leaf surface five-fold. needle-pricking showed a significant reduction lesions treated (av. 59.7%), compared to untreated control. We found titer is 10-fold higher infection but it still discoverable even absence specific host leaves. This first report assessment locally isolated phages against BS Bulgaria.
