KEGG pathway classification statistics of the metabolites identified in the extracts of eight quinoa accessions. The histogram is divided into four parts, labeled A, B, C, and D, representing the KEGG metabolic pathways of ETDW, ET, EA, and HE extracts, respectively. The ordinate represents the names of KEGG metabolic pathways, while the abscissa shows the number of materials annotated in each pathway. The histogram uses color to indicate the unique metabolic pathways of a particular solvent. Source: KEGG Pathway Database29,30,31.
