Abstract
The genetics of pigment production and its control in maize are well understood (Figure 1). Two classes of regulatory genes (b/r andc1/pℓ), required for the transcription of the genes encoding the anthocyanin biosynthetic enzymes (target genes), have been characterized (Paz-Ares et al. 1986; Dellaporta et al. 1988; Chandler et al. 1989; Cone and Burr 1989). The proteins encoded by C1 and Pℓ alleles are 90% identical (K. Cone, personal communication). C1 alleles function in the seed and embryo, while Pℓ alleles function in most seedling and plant tissues. The proteins encoded by the B and R genes are 80% identical (Radicella et al. 1991), and both genes have a large allelic diversity with respect to their tissue-specific expression (Styles et al. 1973). Six target genes have been cloned, c2 (Wienand et al. 1986),chi (Grotewold and Peterson 1991), al (O’Reilly et al. 1985), a2 (Menssen et al. 1990), bzl (Fedoroff et al. 1984), and bz2 (McLaughlin and Walbot 1987; Theres et al. 1987). Herein, we review recent data on each class of regulatory protein and discuss models for their mechanism of action.
