Identification of common differentially abundant metabolites in developing seeds of B. juncea. (a–c) Volcano plots of differentially abundant metabolites. Each point in a volcano plot represents a metabolite; the abscissa represents the logarithm of the quantitative difference multiples of a metabolite in two samples, and the ordinate represents the variable importance in project (VIP) value. The green dots represent down-regulated differentially abundant metabolites, the red dots represent up-regulated differentially abundant metabolites, and the black dots represent metabolites with no difference. (d) Venn diagram of differentially abundant metabolites in developing seeds of B. juncea. DAP = days after pollination.
