Multiple AcSp1 loci in Argiope . Maximum likelihood nucleotide trees of PCR amplified sequences from the (A) repetitive, (B) N-terminal, and (C) C-terminal coding regions of AcSp1 from three Argiope species, A. argentata (Aarg; orange), A. aurantia (Aau; blue), and A. trifasciata (At; green). Araneus ventricosus (Av; black) sequence (GenBank HQ008714) was used to root repeat and C-terminal trees. N-terminal tree is midpoint-rooted (B). For each variant, the adjacent table row indicates the status of that variant in individual spiders. Each individual per species was assigned a number that appears in the corresponding row if a variant was detected. Bootstrap values of 100% are shown. * denotes outgroup or published A. trifasciata sequence (GenBank AY426339), scale bar represents substitutions per site. Accession numbers for sequence generated in this study are given in Additional file 2: Table S4.
