Abstract excerpt

The b gene of maize encodes a transcriptional activator of anthocyanin pigment biosynthetic genes. Certain b alleles undergo paramutation: a unidirectional, heritable alteration of one allele caused by the presence of another allele. B-I (intensely pigmented plant) is always changed to B' (weakly...
