Comparison of the 30 most highly expressed genes between P. xuthus , P. polytes and B. mori. B. mori data is from [25]. The 30 most highly expressed genes were color-coded in accordance with similarity of abundance of epidermal expressed sequence tag clones (red indicates genes which are among the 30 most highly expressed genes of both P. xuthus and P. polytes, or P. xuthus and B. mori; orange indicates genes which are among the 30 most highly expressed genes in one library and the 100 most highly expressed genes in another library; gray indicates the genes which are among the 30 most highly expressed genes in one species and out of the 100 most highly expressed genes in other species; and white indicates genes among the 30 most highly expressed genes in one species but not found in another species). Green circles indicate the Papilio-specific highly expressed genes ranking in the 30 most highly expressed genes of both P. xuthus and P. polytes datasets but not found in the B. mori library.
