The maize P gene, which specifies red pigmentation of the kernel pericarp, cob, and other floral organs, has been an important model since the early days of modern genetics. Here we show that P encodes a Myb homolog that recognizes the sequence CCT/AACC, in sharp contrast with the C/TAACGG bound by vertebrate Myb proteins. P binds to and activates transcription of the A1 gene required for 3-deoxy flavonoid and phlobaphene biosynthesis, but not the Bz1 gene required for anthocyanin biosynthesis… Expand
