Figure 9. Metabolite-gene expression correlation analysis associated with anthocyanin, carotenoid and ABA metabolism
Pearson’s coefficient-based correlation matrices from selected gene expression levels with two major identified delphinidin glycosides for (a ) control vs red (b ) control vs blue contrasts. The size and color of dots represents the strength of correlation from positive (blue) to negative (red) correlations arranged in an upper triangular matrix.
