Figure 1

Schematic representation of the six P450 genes and the inserted twelve transposons. The P450 genes are shown to scale with exons depicted as filled pink boxes, introns as pink lines, and 5'/3'-flanking sequences as blue lines. The transposons are represented as colored inverted triangles with their names, orientations (horizontal arrows above triangles) and insertion positions (vertical arrows below triangles). Triangles with an identical color are different copies of one transposon. The red vertical arrow below the CYP321A2 indicates its heme-binding site in protein.
