P. perniciosus tra genomic organization and evolution. a Ppetra gene locus and sex-specific transcripts. Azure boxes represent male-specific untranslated regions. Pink boxes represent female-specific untranslated regions. Blue and red boxes represent male-specific and female-specific coding regions, respectively. Striped blue-red boxes represent coding regions utilized both in the male and female sex. Yellow vertical bars indicate the position of the putative TRA/TRA-2 binding sites. b Comparison of tra gene structures in Phlebotomus species. c WebLogo consensus sequence of the putative TRA/TRA-2 binding sites identified in Phlebotomus tra species and of TRA/TRA-2 binding sites of Brachycera tra genes
