Peptidase expansions in the genome of A. echinatior. (A) Expansion of the M16 peptidase gene family with the insulin degrading enzyme, present in one or two copies in all investigated insect genomes (below dotted line), and nardilysin genes (above dotted line). The A. echinatior genes in each group are highlighted in yellow. Bootstrap support values >60% are given. (B) Expansion of the M14 peptidase gene family, with a dotted line separating two subfamilies. The A. echinatior genes are highlighted in yellow. Bootstrap support values >60% are given. Phum was included to increase resolution of this tree. Species (A. echinatior: Aech; H. saltator: Hsal; C. floridanus: Cflo; S. invicta: Sinv; A. mellifera: Amel; D. melanogaster: Dmel; N. vitripennis: Nvit; Pediculus humanus: Phum) and GenBank ID are given for each sequence.
