Relationship of PvNod41 to other plant aspartic proteases. Phylogenetic relationship between PvNod41 and aspartic peptidases of the A1B subfamily. Groups of representative aspartic peptidases such as CDR1 (A), nepenthesin (B), CND41 (C), PCS1 (D) and nucellin (E), were used for the analysis. Phytepsins of peptidase subfamily A1A were included as an outgroup. Database accession numbers are indicated. The phylogenetic tree was constructed using the Maximum Likelihood method based on protein sequences. Numbers represent number of substitutions per site along the branch. At, Arabidopsis thaliana; Gm, Glycine max; Hv, Hordeum vulgare; Le, Lycopersicon esculentum; Lj, Lotus japonicus; Mt, Medicago truncatula; Ng, Nepenthes gracilis; Ns, Nicotiana sylvestris; Nt, Nicotiana tabacum; Os, Oryza sativa; Ps, Picea psitchensis; Pt, Populus trichocarpa; Pv, Phaseolus vulgaris; Vv, Vitis vinifera.
