The Regulation of Anthocyanin Synthesis in the Wheat Pericarp
Bread wheat producing grain in which the pericarp is purple is considered to be a useful source of dietary anthocyanins. The trait is under the control of the Pp-1 homoealleles (mapping to each of the group 7 chromosomes) and Pp3 (on chromosome 2A). Here, TaMyc1 was identified as a likely candidate...

The gene encodes a MYC-like transcription factor.
