Schematic representation of P1 promoter regions and radial trees of non- coding P1 sequences. (A) Schematic representation of distal (−5282 to −4653) and basal (−1100 to +1) promoter regions (dashed boxes), within the P1 gene. Distances are represented at scale. (B) Phylograms (radial tree) of both promoter regions of the P1 gene in different landraces, B73 and W23 inbred lines.
