The maize pl locus encodes a transcriptional activator of anthocyanin biosynthetic genes. The Pl-Rhoades (Pl-Rh) allele confers robust purple anthocyanin pigment in several tissues. Spontaneous derivatives of Pl-Rh, termed Pl'-mahogany (Pl'-mah), arise that confer reduced pigment and are meiotically heritable. These derivatives influence other Pl-Rh alleles such that only Pl'-mah alleles are transmitted form a Pl-Rh/Pl'mah heterozygote. Genetic crosses establish that chromosomal segregation distortion does not explain this exclusive transmission and suggest that Pl-Rh invariably changes to Pl'-mah when exposed to Pl'-mah. Such behavior is a hallmark of paramutation. Cosegregation experiments demonstrate that this paramutagenic activity is genetically linked to the pl locus. By visually quantifying pl action through successive crosses, we find that phenotypic expression is inversely related to paramutation at two other maize loci, b and r. Previous analysis of b and r paramutation revealed extensive differences and led to suggestions of distinct molecular mechanisms. Consideration of the common features of all three systems reinvigorates the interpretation that the mechanistic processes of these three allelic interactions are similar.
