Fig. 4: Phenylpropanoids and branching pathways are differentially regulated in Z. tritici-resistant and Z. tritici-susceptible wheat cultivars.

a Biosynthesis pathway of phenylpropanoids and branching biosynthesis pathways (modified from KEGG map00940). Compounds with significant differences in the comparison between treatments, cultivars, or leaf positions are highlighted in orange (Obelisk), green (Chinese Spring), or green/orange (Chinese Spring and Obelisk), respectively. nd not detected, ns not significant, Ob Obelisk, CS Chinese Spring. b Detailed information on metabolites with significant differences as highlighted in (a) and metabolites with significant differences from branching biosynthesis pathways. DAMs from the comparison “treatment” are named “m_” or “Zt_”, DAMs from the comparison “cultivar” are named “Ob_” or “CS_”, DAMs from the comparison “position” are named “loc_” or “adj_”. Details on the labeling can be found in Supplementary Fig. 8c. Number of biologically independent replicates: n = 3. For details on the statistical analysis of the metabolomics dataset, please see the methods section. *P < 0.05; **P < 0.01; ***P < 0.001.
