Abstract excerpt
The maize r locus encodes a transcription factor that regulates the developmental expression of the plant pigment anthocyanin. In an unusual example of gene regulatory diversity, the R-sc (Sc, strong seed color) and the R-p (P, plant color) alleles of r have nonoverlapping tissue specificity and nonhomologous 5' flanking sequences. Heterozygotes between wild-type P and Sc mutants with Ds6 transposable element...
