Consequences of disrupting Salmonella AI-2 signaling on interactions within soft rots.

Phytopathology - 1 Apr 2013

Cox Clayton E, McClelland Michael, Teplitski Max

Abstract excerpt

Within soft rots, Salmonella spp. reach population densities 10- to 100-fold higher than within intact plants. The hypothesis that Salmonella spp. exchange AI-2 signals with Pectobacterium carotovorum to increase its competitive fitness was tested using mutants involved in AI-2 production (luxS) or perception (lsrACDBF or lsrG). Co-infections of a wild-type Salmonella sp. and its AI-2 mutants (at ≈3 to 10(4))...
