HsTRPA has evolved by duplication of the Wtrw gene. Positions of AmWtrw and AmHsTRPA genes on A. mellifera Group 2.21 scaffold as well as NvWtrw and NvHsTRPA on N. vitripennis scaffold 44 are shown. The exons of Wtrw and HsTRPA genes are indicated by red and green rectangles, respectively. The numbers indicate the sizes of DNA (bp), and the arrows show the direction of transcription of genes. AmWtrw, AmHsTRPA, and NvHsTRPA have no introns, while NvWtrw has 2 introns. The genes adjacent to Wtrw and HsTRPA are also conserved between Apis and Nasonia.
