Fig. 3From: Flavonoid Metabolic Profiles and Gene Mapping of Rice (Oryza sativa L.) Purple Gradient Grain HullsComparative enrichment of differential metabolites in distinct Kyoto Encyclopedia of Genes and Genome (KEGG) pathways. The metabolic pathways associated with metabolites in pg-10d (a), pg-20d (b), and pg-30d (c) differed from those in pg-0d. A hypergeometric distribution was used to compute p-values for enrichmentBack to article page
