The c-di-GMP phosphodiesterase BifA is involved in the virulence of bacteria from the Pseudomonas syringae complex.

ABSTRACT: In a recent screen for novel virulence factors involved in the interaction between Pseudomonas savastanoi pv. savastanoi and the olive tree, a mutant was selected that contained a transposon insertion in a putative cyclic diguanylate (c-di-GMP) phosphodiesterase-encoding gene. This gene displayed high similarity to bifA of Pseudomonas aeruginosa and Pseudomonas putida. Here, we examined the role of BifA in free-living and virulence-related phenotypes of two bacterial plant pathogens in the Pseudomonas syringae complex, the tumour-inducing pathogen of woody hosts, P. savastanoi pv. savastanoi NCPPB 3335, and the pathogen of tomato and Arabidopsis, P. syringae pv. tomato DC3000. We showed that deletion of the bifA gene resulted in decreased swimming motility of both bacteria and inhibited sw
