Blastx of putative N-terminal DLD consensus sequences predicted from transcripts from adult T. castaneum strains exposed or not to phosphine, with sequences from a the phosphine-susceptible strain and b phosphine-resistant strain; all were “Queries” to QTC4 “Subject” (gi|399108166|gb|AFP20530.1|). Differences between the phosphine-susceptible, - resistant, and QTC4 sequences are boxed. All letters are standard amino acid abbreviations, except X = unknown (but was a mixture of serine and proline residues). The asterisk denotes the G131S phosphine-resistance mutation described in [10]
