Fig. 2From: Integrated metabolomics and transcriptome analysis on flavonoid biosynthesis in safflower (Carthamus tinctorius L.) under MeJA treatmentVolcano plot of differential expression genes. The abscissa represents the change of gene expression multiple (log2 Fold Change), and the ordinate represents the significant level of differentially expressed genes (−log10 False Discovery Rate). The expression of red gene was up-regulated, that of green gene was down-regulated, and that of black gene was not significantly differentBack to article page
