Abstract
Plant-associated Burkholderia spp. offer a promising alternative to pesticides for controlling grapevine grey mold disease. Two Burkholderia strains, BE17 and BE24, inhibited *Botrytis cinerea* spore germination and mycelium growth. Bacterized grapevine plantlets showed significant protection against grey mold, with increased reactive oxygen species, callose deposition, and expression of PR5 and PR10 genes (involved in the salicylic acid signaling pathway). Genomic analysis revealed genes involved in plant growth promotion and biocontrol, highlighting the strains' potential for sustainable agriculture.
