Comparison of CO2 receptor gene structures between D. v. virgifera and T. castaneum. Exons and introns located within the coding regions are depicted by boxes and peaks with their lengths (bp), respectively. The total length (bp) of each coding region is shown in square brackets. D. v. virgifera gene structures were determined by comparing transcript sequences and the draft genome sequence (Hugh Robertson, personal communication). Exon–intron structures for T. cantaneum CO2 receptor genes are based on the annotations available in the BeetleBase [39]: TC030102 (TcasGr1), TC030103 (TcasGr2), and TC030104 (TcasGr3)
