R-nj phenotype was restored when the two R-nj components, Sc and Nj, were brought together in the same individual in trans configuration. This complementation has demonstrated that these two components, Sc and Nj, are closely linked independent genes with different functions. The Sc gene is responsible for anthocyanin pigment production in the aleurone tissue, while Nj gene is regulatory in nature controlling the onset, termination or period of Sc gene action.
