Opsin cDNA sequences of a UV and green rhodopsin of the
satyrine butterflyBicyclus anynana.
Insect Biochem Mol Biol. 2002 Nov;32(11):1383-90.
The cDNAs of an ultraviolet (UV) and long-wavelength (LW)
(green) absorbing rhodopsin of the bush brown Bicyclus anynana were partially identified. The UV sequence, encoding 377 amino acids, is 76-79% identical to the UV sequences of the papilionids Papilio glaucus and Papilio xuthus and the moth Manduca sexta. A dendrogram derived from aligning the amino acid sequences reveals anequidistant position of Bicyclus between Papilio and Manduca. The sequence of the green opsin cDNA fragment, which encodes 242 amino acids, represents six of the seven transmembrane regions. At the amino acid level, this fragment is more than 80% identical to the corresponding LW opsin sequences of Dryas, Heliconius, Papilio
(rhodopsin 2) and Manduca. Whereas three LW absorbing
rhodopsins were identified in the papilionid butterflies,
only one green opsin was found in B. anynana.
Bicyclus anynana: English name:the bush brown. Japanese name: （アフリカ産ジャノメチョウの一種。蝶における季節要因のポリフェニズム例の典型）. The butterflies of the dry-season form survive hidden in the dry vegetation. They are colored with a gray-brown pattern and thus display a mimetic coloration. In contrast, butterflies of the wet-season form display a system of eyespots and contrasted bands.
