 This research paper examines the relationship between the accumulated anthocyanin content and the expression levels of genes related to the biosynthesis of anthocyanins in rice seeds. The authors found that the genes involved in the biosynthesis of anthocyanins were differentially upregulated in developing seeds of black rice. They also discovered that the quantities of C3G biosynthesized in black rice seeds were positively correlated with the expression levels of BHLHS, MYBs, and WD40, CHS, F3H, F3H, DFR, and ANS. This suggests that the biosynthesis of anthocyanins in black rice seeds may be controlled by the expression levels of these genes.
