Endophytic bacteria from strawberry plants control gray mold in fruits via production of antifungal compounds against Botrytis cinerea L.

•Strawberry leaves and roots are colonized by endophytic bacteria with the potential to indirectly promote plant growth.•Endophytic bacteria from strawberry leaves and roots synthesized diffusible and volatile compounds against Botrytis cinerea.•Bacillus spp. and Pantoea sp. strains showed a greater potential for biological control of B. cinerea in vitro and in vivo.•Bacillus spp. and Pantoea sp. strains isolated from strawberry leaves and roots caused damages on B. cinerea hyphae.•Bacillus spp. and Pantoea sp. strains selected in vitro exuded bioactive compounds with proven antifungal activity.
