“…Pseudomonads are gramnegative bacteria and may have lectin binding structures in the LPS and EPS layers of the cell wall membrane (Lotan et al, 1975). These surface structures of bacterial cell walls adhere specifically and strongly to cell wall structures of the plant (Costerton et al, 1989) and are important virulence factors of plant pathogenic bacteria (Mansfield and Brown, 1986). They are also considered to affect physiological reactions in plants.…”

Bare-root-dip treatment or soil drench with Pseudomonas aeruginosa strain IE-6S þ and P. fluorescens CHA0 significantly suppressed Rhizoctonia solani and the bacterial efficacy was more pronounced in the presence of low inoculum level of the fungus. The two bacteria afforded better protection to tomato roots against R. solani during early growth stages of the roots. There was a significant difference in the level of protection between root-dip treatment and soil drench with both the bacterial inoculants. The ability of the antagonistic bacteria to induce systemic resistance against R. solani was demonstrated in splitroot trials, where the root system of a single tomato plant was spatially divided into two separate parts. Root infection caused by R. solani was substantially lower in both bacterized and non-bacterized halves. However, the level of protection was greater in the bacteria-treated half compared with the bacteria-free half. Viable and dead cells of the two bacteria showed similar activity against R. solani, while the culture filtrate of P. fluorescens induced systemic resistance of a higher degree towards R. solani compared with P. aeruginosa. In general, populations of the two bacteria in the rhizosphere declined by tenfold at each harvest and colonization of P. aeruginosa was slightly greater compared with that by P. fluorescens. Initially (day 0), both the bacterial inoculants had almost a similar pattern of rhizosphere colonization, whereas at first (day 7) and second harvest (day 14) P. aeruginosa colonized more heavily than P. fluorescens. At final harvest (day 21), the two bacteria did not differ significantly in their colonization pattern. Whereas P. fluorescens specifically colonized the rhizosphere, P. aeruginosa also colonized the inner root tissues of tomato.U. S.

“…Given the postulated role of hydrogen peroxide as a plant defense mechanism, it is surprising to find that, though sensitive to oxidative stress, OT1.Cm5 retains virulence. A likely explanation is that when infecting host plants E. amylovora evades recognition and does not trigger defense mechanisms (21), so levels of hydrogen peroxide in plant tissues remain low and the survival of the mutant strain is not compromised.…”
