Impact of Bacillus cereus NRKT on grape ripe rot disease through resveratrol synthesis in berry skin
Pest Management Science 73 (1), 174-180
Abstract:
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.
