Résumé
Selected strains of fluorescent pseudomonads suppress various plant diseases caused by soil-borne pathogenic fungi, by a blend of several mechanisms including aggressive root colonization, antibiosis, competition for nutrients, induction of resistance in the plant, and enzymatic attack of the pathogen. These traits are amenable to genetic analysis and, therefore, to modification by genetic engineering. Biocontrol activities of Pseudomonas spp. have been enhanced in two ways: (i) by overexpression of traits known to involved in diseaese suppression, and (ii) by introduction of additional beneficial traits into strains having basal biocontrol activities. Under experimental conditions in microcosms, a number of genetically modified Pseudomonas strains have given promising results. It remains to be seen whether such strains will be superior to the best naturally occurring strains, applied singly or in combination, under greenhouse and field conditions.
