Epigenetic allelic states of a maize transcriptional regulatory locus exhibit overdominant gene action.

Genetics - 1 Oct 1998

Hollick J B, Chandler V L

Abstract excerpt

Using alleles of the maize purple plant locus (pl), which encodes a transcriptional regulator of anthocyanin pigment synthesis, we describe a case of single-locus heterosis, or overdominance, where the heterozygote displays a phenotype that is greater than either homozygote. The Pl-Rhoades (Pl-Rh...
