Note: The fold change in each substance was obtained from the relative quantitative value of the metabolites in one treatment divided by the relative quantitative value of the metabolites in the other. The significant values were confirmed by Student’s t-tests. *A significant difference (0.001< p < 0.05); **A extremely significant difference (p < 0.001). EF, endophyte-free plants; EI, endophyte-infected plants; EFCL, EF plants inoculated withCurvularia lunata ; EICL, EI plants inoculated with C. lunata.
