Insights into the molecular evolution of peptidase inhibitors in arthropods
Fig 5
Phylogenetic distribution and divergence rates in peptidase inhibitory families with species-rich clades.
Schematic PhyML phylogenetic trees using the inhibitory domains from the selected arthropod species are depicted. Coloured triangles show collapsed branches. Triangle size is proportional to the number of nodes (domains) included. The number of species with any domain in the collapsed branch is indicated. Numbers after species abbreviation indicate the number of inhibitory domains in the branch. In parentheses the number of inhibitory domains in a species-rich clade. aLRT values over 50 are shown. LRT Theta values for Type I functional divergence between numbered clades are included. Dm, Drosophila melanogaster; Cf, Camponotus floridanus; Ap, Acyrthosiphon pisum; Dp, Daphnia pulex; Tu, Tetranychus urticae; Sm, Strigamia maritima. Complete phylograms are shown in S3 Fig.
