Figure 4From: Promzea: a pipeline for discovery of co-regulatory motifs in maize and other plant species and its application to the anthocyanin and phlobaphene biosynthetic pathways and the Maize Development AtlasThe maize anthocyanin and phlobaphene biosynthesis pathways regulated by transcription factors C1 and P. Genes encoding biosynthetic enzymes regulated by C1 are shown in red text; those also regulated by P are underlined. C1 and P are homologous proteins [21], and they have been shown to interact with identical binding sites in the A1 promoter [18, 22].Back to article page
