The distribution of DAMs related to the responses of wheat in leaves after 30Â days of N/MPs exposure: A PCA of DAMs. B Heatmaps of DAMs compared between different groups. C Volcano plots displaying the DAMs that are up- and down-regulated. Red plots represent upregulated DAMs; green plots represent downregulated DAMs; blue plots represent metabolites with no significant difference. D KEGG pathway enrichment analysis of DAMs
