Volcano maps of differential metabolites in four pairwise comparisons: (a) WL440_2 vs WL440_1; (b) ZD_2 vs ZD_1; (c) ZD_1 vs WL440_1; (d) ZD_2 vs WL440_2. Note: Volcano map is used to show the relative content difference of metabolites between the two groups of samples and the statistical significance of the difference. Each point in the volcano map represents a metabolite, where red points represent up-regulated differential metabolites, gray points for non-significantly different metabolites, and green points for down-regulated differential metabolites. The abscissa represents the logarithmic value (log2 FC) of the multiple difference of the relative content of a metabolite in the two groups of samples. The larger the absolute value of the abscissa, the greater the relative content difference of the metabolite between the two groups of samples. The ordinate represents the VIP value, and the larger the ordinate value, the more significant difference is and the more reliable the differential metabolites obtained by screening.
