Introduction Botrytis cinerea is one of the pathogenic fungi causing major problems worldwide in crops such as tomato. Some Plant Growth-Promoting Rhizobacteria (PGPR) can activate induced systemic resistance (ISR) pathways crops, reducing need for antifungals. Methods Three strains belonging to species Peribacillus frigoritolerans (CD_FICOS_02), Pseudomonas canadensis (CD_FICOS_03), and Azotobacter chroococcum (CD_FICOS_04), which exhibit outstanding PGPR properties, were evaluated their ability protect tomato plants against B. infection by ISR via soil inoculation. Results The CD_FICOS_02 CD_FICOS_03 reduced incidence plant oxidative stress. first strain mainly increased expression genes related salicylic acid pathway, while second jasmonic acid/ethylene hormonal indicating preferential activation each these pathways. In addition, was able increase root aerial biomass production infected compared control. Interestingly, although CD_FICOS_04 did not reduce damage caused , it plants. Discussion Our results suggest that best strategy biocontrol combine promote growth with induce resistance, demonstrated P. CD_FICOS_03.
