Infection with S. oryzae substantially altered metabolomes under K-starvation and K sufficient conditions, especially with respect to amino acids and lipid products. The data shown are log₂(Fold Change) values of the metabolites (n = 6 biologically independent replicates), and the treatments in brackets were performed as controls. The 147 metabolites were clustered according to their metabolic pathways and functions, as suggested by previous study (McLoughlin et al. 2018). Additionally, p-value ≤ 0.05 and FDR ≤ 0.05 were set as the screening criteria for multiple comparisons. Red denotes higher log₂(FC) values for the treatments, and blue denotes higher log₂(FC) values for the controls (indicated in brackets). − and + indicate before inoculation and 5 days after inoculation (sterile water or S. oryzae), respectively
