BACKGROUND: Vine growers are faced with the difficult problem of how to control grape ripe rot disease in vineyards because of fear of accumulation of pesticide residues on grape berries near harvest. Biological control is an alternative non-hazardous technique to control the diseases. RESULTS: Application of resveratrol-synthesis-promoting bacterium, Bacillus cereus strain NRKT, reduced the incidence of grape ripe rot disease caused by Colletotrichum gloeosporioides in a vineyard. The application of NRKT to berry bunches upregulated the gene expression of stilbene synthase, a key enzyme for resveratrol synthesis in berry skins, thereby promoting resveratrol synthesis in berry skins. CONCLUSION: The potential use of NRKT in vineyards is expected to contribute to the increase in resveratrol content in berry skins, thereby protecting grape berries against fungal diseases.
