Functional relevance of metabolome changes during abiotic stress conditions.

Significant enrichment in Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways was determined based on tentative annotations of SAMs under each abiotic stress treatment (adjusted P$\le$ 0.05, Fisher’s exact test). Circle size is proportional to the number of metabolites included in the pathway, and color code indicates the degree of enrichment significance based on adjusted P as −log₁₀(FDR). KEGG pathways significantly enriched in transcriptome data (adjusted P$\le$ 0.05, Fisher’s exact test, Supplemental Table 6) for late-changing events are circled in blue. Pink squares highlight groups of pathways involved in the metabolism of carbon, amino acids, and secondary metabolites.
