COMPLEMENTARY GENIC COMPLEX FOR ANTHOCYANIN PIGMENTATION IN THE APICULUS OF RICE (ORYZA SATIV AL.)

Abstract

The C-A-P genie complex for anthocyanin pigmentation in the apiculus of japonica rice has been recently found to be also applicable to indica rice. The present investigation reveals a considerable difference in the nature and the number of localization genes. Accordingly, the complementary genie complex for anthocyanin pigmentation in the apiculus of both japonica and indica rices is C-A-PaPb or C-A-PaPc or C-A-PbPc. Any two of the localization genes (Pa, Pb, Pc,) together also act as basic genes for other localization genes governing anthocyanin pigmentation in all other parts of the plant.

Polyphenols in whole rice grain: Genetic diversity and health benefits

“…tary genetic system which consists of three basic genes as C (chromogen), A (activator), and P (distributor) (Setty & Misro, 1973). The gene C governs the production of chromogen, the gene A converts or oxidizes chromogen into anthocyanins, and the regulatory gene P determines the temporal and spatial regulation of pigmentation (Setty & Misro, 1973).…”

“…The gene C governs the production of chromogen, the gene A converts or oxidizes chromogen into anthocyanins, and the regulatory gene P determines the temporal and spatial regulation of pigmentation (Setty & Misro, 1973). Currently, the biosynthetic pathway of polyphenols has become much clearer, being controlled by many structural and regulatory genes derived from L-phenylalanine (Fig.…”
