The efficacy of hexanoic acid (Hx) as an inducer of resistance in tomato plants against Pseudomonas syringae pv. tomato
DC3000 was previously demonstrated, and the plant response was characterized. Because little is known about the reaction
of the pathogen to this effect, the goal of the present work was to determine whether the changes in the plant defence
system affect the pathogen behaviour. This work provides the first demonstration of the response of the pathogen to the
changes observed in plants after Hx application in terms of not only the population size but also the transcriptional levels of
genes involved in quorum sensing establishment and pathogenesis. Therefore, it is possible that Hx treatment attenuates
the virulence and survival of bacteria by preventing or diminishing the appearance of symptoms and controlling the growth
of the bacteria in the mesophyll. It is interesting to note that the gene transcriptional changes in the bacteria from the
treated plants occur at the same time as the changes in the plants. Hx is able to alter bacteria pathogenesis and survival
only when it is applied as a resistance inducer because the changes that it promotes in plants affect the bacteria. [-]
