cDNAs were derived from three Hessian fly populations: biotype GP, biotype L, and a Syrian population (S). As a control, cDNAs coding for 26 different ribosomal proteins (RPs) that were isolated along with SSSGP cDNAs were included in this analysis. Sequence alignments for different SSSGP cDNAs are shown in Additional file 6, Figure S6 whereas alignments for RP cDNAs are shown in Additional file 7, Figure S7. "Nonsyn/Syn" represents the ratios of non-synonymous against synonymous substitutions in SPCR and MPCR, respectively.
