Established <i>Pseudomonas syringae</i> pv. <i>tomato</i> infection disrupts immigration of leaf surface bacteria to the apoplast.

ABSTRACT: Bacterial disease alters the infection court creating new niches. The apoplast is an oasis from the hardships of the leaf surface and is generally inaccessible to nonpathogenic members of the phyllosphere bacterial community. Previously, we demonstrated that Salmonella enterica serovar Typhimurium (S. Typhimurium) immigrants to the leaf surface can both enter the apoplast and replicate due to conditions created by an established Xanthomonas hortorum pv. gardneri (Xhg) infection in tomato. Here, we have expanded our investigation of how infection changes the host by examining the effects of another water-soaking pathogen, Pseudomonas syringae pv. tomato (Pst), on immigrating bacteria. We discovered that, despite causing macroscopically similar sympt
