a Pie charts illustrating the number of differentially abundant metabolites in wild and domesticated rice within the different compositional categories. The differentially abundant root metabolites were identified by a comparison of wild and domesticated rice (Welch’s t-test, p < 0.05). b A line chart shows the dynamics of the abundance of nifH gene after root metabolites inoculation in soil. The treatments are as follows: CK: sterilized distilled water; Wild: wild rice root metabolites solution; Domesticated: domesticated rice root metabolites solution. Vertical bars indicate the standard error of the mean (n = 5 biological replicates). c Nitrogenase activity at 36 h. The error bars represent the standard deviation of the mean (n = 4 biological replicates), and different letters indicate significant differences between wild and domesticated rice (one-way ANOVA, p = 2.03E-09). Data were presented as mean values ± SD. Source data are provided as a Source Data file.
