Históricamente, el tizón de fuego (causado por la bacteria Erwinia amylovora) ha sido un referente en estudio enfermedades plantas. La comprensión y esta enfermedad han beneficiado a fitopatología, además, propiciado avances importantes otras ciencias como biotecnología microbiología. Hoy día, creciente resistencia frente los antibióticos utilizados para su control alerta sobre uso indebido est...
fire blight, caused by the bacterium erwinia amylovora, is one of the most destructive diseases of plants in the rosaceae subfamily pomoideae. the objective of this study was to determine the level of resistance of 30 pear cultivars and describe the biochemical changes induced in some resistant and susceptible cultivars. the level of resistance was determined by the length of the fire blight le...
DNA fragments with ams genes of Erwinia amylovora and cps genes of Erwinia stewartii were transferred to exopolysaccharide (EPS)-deficient mutants of the other species. The resulting EPSs were characterized by sensitivity to EPS-dependent bacteriophages, staining with amylovoran-specific fluorescein-isothiocyanate-labelled lectin and chemical techniques, such as determination of the sugar compo...
