Each value is the mean of three replicates (± SD). Values followed by different lowercase letters indicate significant differences (P < 0.05) between samples in a row. NO, nitric oxide; SNP, exogenous NO donor sodium nitroprusside. Control-M treatment, the rhizosphere soil of inoculated C. illinoinensis seedlings that had no SNP application; SNP treatment, the rhizosphere soil of inoculated C. illinoinensis seedlings treated with 100 μmol/L SNP. M0, M1, M2, M3, M4, M5, and M6 represent rhizosphere soil harvested on month 0, 1, 2, 3, 4, 5, and 6, respectively, after T. indicum inoculation.
