Colonization of Xanthomonas euvesicatoria was investigated in pepper blossoms and the relationship between inoculum concentrations seed infestation determined. Inoculation resulted asymptomatic fruit. However, real-time polymerase chain reaction detected X. 39% lots assayed viable colonies were recovered from 35% them. Successful transmission occurred 16% tested. In a separate experiment, reached populations up to 1 × 10 5 CFU/blossom on stigmas 96 h after inoculation. Bacteria colonized stylar ovary tissues with ranging 6 A positive correlation existed concentration percentage infested seedlots. Blossoms inoculated Acidovorax citrulli also Furthermore, A. significantly better than by postinoculation. It concluded that can be potential site ingress for into seed, blossom colonization may involved infestation. Data indicated via nonspecific because nonhost plants incompatible pathogens. Thus, host–pathogen interactions not important bacterial through blossoms.
