Figure 5. Coleoptera elevenins.

Alignment of the predicted Coleoptera elevenins as obtained by conceptual translation of their putative transcripts. The sequences include the processing sites of peptides; where these are lacking on the N-terminal, cleavage is obtained by a signal peptidase. The species are arranged according to their position on the phylogenetic tree as established by Zhang et al. (2018). Tree branches have been made red where the peptide and its receptor were lost from the genome, which must have occurred on at least three occasions. Note that the peptide sequence is not very well conserved and that in both Dendroctonus and Hypothenemus an additional cysteine bridge has been added to the peptide.
