Phylogenetic and domain analysis of Dicer and Drosha proteins. a Maximum-likelihood based phylogenetic analysis (1000 bootstrap replicates) of Dicer and Drosha amino acid sequences of six tsetse species based on full length alignment with D. melanogaster orthologs as outgroup. b Domain architecture of Dicer and Drosha proteins. Some of the tsetse species had either DCR1 or DCR2 proteins, but Drosha was found in all the species. The numbers on the domains are the scores produced by the ScanProsite search compared to the PROSITE protein domain database. All DCR1, DCR2 and Drosha proteins show similarity in the domain architectures to Dmel-DCR1, Dmel-DCR2 and Dmel-Drosha, respectively. Abbreviations; DCR (Dicer), Gp (G. pallidipes), Gmm (G. m. morsitans), Gff (G. f. fuscipes), Gbr (G. brevipalpis), Gpp (G. p. palpalis), Gaus (G. austeni) and Dmel (D. melanogaster)
