摘要： Cherry tomatoes, a nutritious and economically valuable global crop, suffer major postharvest losses annually due to grey mold (Botrytis cinerea) infections. According to reports, microorganisms produce volatile organic compounds (VOCs) can inhibit plant pathogens and avert disease. A previous study demonstrated Bacillus siamensis VOCs can inhibit several fungal pathogens, but their ability to prevent postharvest grey mold in cherry tomato fruit and the underlaying molecular mechanism responsible for the inhibition have not been investigated. The present study revealed the ability of B. siamensis VOCs to significantly inhibit colony growth and spore germination in B. cinerea in vitro and reduce grey mold of cherry tomato fruit. B. siamensis VOCs also decreased natural disease incidence of cherry tomatoes, and delayed fruit softening, as well as the loss of Vitamin C, and the reduction in peroxidase (POD) activity. Cherry tomatoes exposed to B. siamensis VOCs also had lower levels of respiration intensity, and malondialdehyde (MDA) content, relative to control fruit. Transcriptome analysis indicated that B. siamensis VOCs induced the downregulation of genes in B. cinerea involved in glycerophospholipid metabolism, amino and nucleotide sugar metabolism, tryptophan metabolism, as well as genes involved in pathogenicity. Collectively, results indicated that B. siamensis VOCs inhibit B. cinerea on harvested cherry tomato fruit by mediating the metabolism and pathogenicity of B. cinerea. These results enhance comprehension of the mechanisms by which B. siamensis VOCs exerts antimicrobial activity.
