From: Plant protein peptidase inhibitors: an evolutionary overview based on comparative genomics
Number of peptidases and their inhibitors in selected plant species. Schematic evolutionary tree of fully sequenced plants including for each species the number of peptidase (C1A Papain and S8 Subtilisin) and peptidase inhibitory sequences (I plus number and name). In brackets the number of inhibitory domains for families I1, I3, I4, I6, I12 and I20; or the number of sequences with an additional cystatin-like domain for I25 family. Algae species are coloured in blue, moss in green, pseudofern in yellow, monocots in orange and eudicots in pink.
