Dendrogram of the Glossina morsitans morsitans salivary endonuclease-like proteins with the Culex quinquefasciatus salivary endonuclease included as an outgroup. The G. m. morsitans sequences are indicated by GM-X where X is the number shown in additional file 2. The remaining sequences derived from the National Center for Biotechnology Information (NCBI) are represented by five letters followed by the NCBI gi| accession number. The five letters are taken from the first three letters of the genus and the first two letters from the species name. The protein sequences were aligned by the Clustal program [176], and the dendrogram was done with the Mega package [178] after 10,000 bootstraps with the neighbor joining (NJ) algorithm. Bootstrap values above 75% are shown in the nodes. The bar at the bottom represents 20% amino acid substitution. The roman numerals indicate clades discussed in the text.
