[more ▼] Root treatment by the non-pathogenic Pseudomonas putida strain BTP1 reduced by 34% the disease caused by Botrytis cinerea on tomato leaves. This induced systemic resistance phenomenon is associated both with the accumulation of fungitoxic material and with the stimulation of the lipoxygenase pathway in infected leaves. More precisely, we observed a consistent change in the expression of a new tomloxF gene in the leaves from BTP1-treated plants as far as the pathogen is introduced. This suggests that the roots were primed and reacted locally to colonization by bacteria and that defense-related gene expression is turned on systemically upon pathogen perception [less ▲] Detailed reference viewed: 43 (10 ULg)PGPR-induced systemic resistance: activity of amphiphilic elicitors and structural analogues on different plant speciesJourdan, Emmanuel ; Ongena, MARC ; et alin Bulletin OILB/SROP = IOBC/WPRS Bulletin (2007), 30 Some non pathogenic microorganisms can induce disease resistance mechanisms expressed systemically in the host plant thereby rendering it less susceptible to further attack by pathogens.

[more ▼] Some non pathogenic microorganisms can induce disease resistance mechanisms expressed systemically in the host plant thereby rendering it less susceptible to further attack by pathogens. In this study, we have investigated the role of bacterial compounds as elicitors of the induced systemic resistance. Lipopeptides, especially surfactin and fengycin, produced by Bacillus subtilis strains are able to stimulate bean and tomato plants and decrease the impact of subsequent pathogen infection. Preliminary experiments on tobacco cells showed that surfactine induces some modifications in the phenylpropanoid pathway. Amphiphilic properties of lipopeptides and NABD, the elicitor isolated from Pseudomonas putida strain BTP1, could be responsible for their activities on plant cells [less ▲] Detailed reference viewed: 82 (5 ULg)Aureobasidium pullulans (de Bary) Arnaud (1113-5) microbial antagonist for the control of postharvest decay of apple fruit: study on the producing and formulating in active biomass in a lab scale; ; et al in Bulletin OILB/SROP = IOBC/WPRS Bulletin (2006), 30 Detailed reference viewed: 12 (0 ULg)Physiological and physico-chemical factors modulating ISR elicitor production by Pseudomonas putidaJourdan, Emmanuel ; Ongena, MARC ; et alin Bulletin OILB/SROP = IOBC/WPRS Bulletin (2006), 29(2) Abstract: A better understanding of biotic and environmental factors that regulate the production of active metabolites by beneficial rhizobacteria is crucial for optimising biocontrol under pratical ... [more ▼] Abstract: A better understanding of biotic and environmental factors that regulate the production of active metabolites by beneficial rhizobacteria is crucial for optimising biocontrol under pratical conditions. In this study, we wanted to evaluate the effect of some parameters on the production of the plant defence elicitor synthesized by Pseudomonas putida BTP1. This molecule is clearly dependant of the secondary metabolism and chemostat experiments showed that the elicitor is more efficiently produced at a very low cell growth rate. On another hand, the presence of free amino acids in the medium is necessary to obtain an optimal NABD production. A specific positive effect of phenylalanine was evidenced in pulsed continuous cultures suggesting that this residue could play a role as a precursor and/or act as a regulator in the biosynthetic pathway.
