Fig. 1. Arthropod opsin gene phylogeny. The phylogeny is based upon a
neighbor-joining analysis of first and second nucleotide positions using the
Tamura–Nei model of evolution with a correction for heterogeneous
patterns of evolution among lineages. A total of 631 nucleotide sites were
used. Numbers at the junctions indicate bootstrap replicates out of 1000
(given as a percentage) in which a particular node is supported. Red indicates
cloned Heliconius erato opsin cDNAs. GenBank accession numbers for
the sequences used in the reconstruction are as follows. Chelicerates:
Limulus polyphemus (lateral eye, L03781; ocelli, L03782).
Crustaceans: Procambarus clarkii (S53494). Insects: Anopheles
gambiae [accession no. is given as supplementary information in Hill et
al. (Hill et al., 2002)];
Antheraea pernyi (AB073299); Apis mellifera (UV,
AF004169; Blue, AF004168; LW, U26026); Bombyx mori
(LWRh1, AB064496), Camponotus abdominalis (LW,
U32502; SW, AF042788); Cataglyphis bombycinus (LW,
U32501; SW, AF042787); Danaus plexippus (UVRh,
AY605546; BlueRh, AY605545; LWRh, AY605544); Drosophila
melanogaster (Rh1, K02315; Rh2, M12896; Rh3,
M17718; Rh4, M17730; Rh5, U67905; Rh6, Z86118);
Homalodisca coagulata (AY588065); Manduca sexta
(Manop1, L78080; Manop2, L78081; Manop3, AD001674);
Megoura viciae (UV, AF189715; LW AF189714);
Papilio glaucus (PglRh1, AF077189; PglRh2,
AF077190; PglRh3, AF067080; PglRh5, AF077191;
PglRh6, AF077192); Oncometopia nigricans (AY725781);
Pieris rapae (PrL, AB177984); Schistocerca gregaria
(Lo1, X80071; Lo2, X80072); Sphodromantis spp.
(X71665). Full-length nucleotide sequences for the Bombyx mori UV,
blue and L opsin coding regions were obtained using a tBlastx search of
GenBank whole genome sequences (wgs), manually removing the introns in
MacClade, and then comparing the coding sequences with partial B.

et al., 1998). The bar indicates the number of
