Fig. 4From: The genetic basis of wing spots in Pieris canidia butterfliesPart of the melanin biosynthesis pathway in insects. The enzymatic reactions that produce two types of melanins, DOPA melanin and dopamine melanin are shown here. Enzymes involved in the catalytic reactions of intermediate substrates are in black, and the genes that encode these enzymes are italicised in pink. Adapted from [37]Back to article page
