✦ Synopsis

Aleurone tissue of c2 Pr, C2 pr, or c2 pr genotypes can utilize either of two flavanones (naringenin, homoeriodictyol) or a flavanonol (dihydroquercetin) to synthesize anthocyanin. The anthocyanins formed have substitution patterns corresponding to those of the precursors, but c2 Pr tissue can hydroxylate the 4'-OH precursor at the 3' position. The results presented suggest that C2 acts before the flavanone step and that the hydroxylation gene (Pr) can act after C2.
