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.
