原始语种摘要: Coronatine (COR) can enhance resistance to P. syringae pv. mori in the mulberry to avoid the outbreak of Mulberry Bacterial Blight. In order to analyze the defensive mechanism, metabolic responses of mulberry leaves to COR were examined by gas chromatography-mass spectrometry and biochemical analysis. Antimicrobial activities of metabolites against P. syringae in vitro were also detected by colorimetric assay. Metabolic profiles revealed that 0.01 μM COR induced changes of various metabolites including organic acids, sugars, alcohols, ketones, phenols, hydrocarbons, and nitrogen or sulfur compounds. In particular, sugars, organic acids, phenols, flavonoids, and nitrogen or sulfur compounds increased significantly in the COR-treated leaves. Biochemical analysis also confirmed above...
