Transcriptome and Metabolome Analysis Unveil Anthocyanin Metabolism in Pink and Red Testa of Peanut (Arachis hypogaea L.)

Figure 2

Significantly changed metabolites (SCMs) in Shanhua15 testa compared to those in Zhonghua12. (a) PCA score plot of metabolites profiles from the Shanhua15 and Zhonghua12 testa. Every point represents an independent biological replicate. (b) Expression patterns of secondary metabolites revealed by metabolomic analysis. (c, d) Volcano plot of the metabolites between Shanhua15 and Zhonghua12. (e, f) Number of SCMs in different categories. S4, Shanhua15 R4 pod period; Z4, Zhonghua12 R4 pod period; S7, Shanhua15 R7 pod period; Z7, Zhonghua12 R7 pod period. -1, -2, and -3 represent the three biological replicates.
