In the present study, the components of the gene regulatory network governing the anthocyanin and proanthocyanidin biosynthesis in barely grain and leaf sheath were identified based on comparative mapping and transcription analysis approaches. The regulatory relationships between the genes were established using unique barley anthocyanin/proanthocyanidin mutants and near-isogenic lines.
