Phylogenetic tree of SCAMP proteins in soybean, Arabidopsis thaliana, maize and rice. The domain amino acid sequences of SCAMP proteins were aligned by Clustal W. The phylogenetic tree was constructed and was rooted by using the human SCAMP2 as the outgroup using the Neighbor-Joining method in MEGA 7.0. The numbers next to the branches are bootstrap values (for 1000 replicates, given as a percentage). Protein sequences of soybean, Arabidopsis thaliana, maize and rice were divided into two Groups, namely, Group 1 and Group 2 in an original tree in a radiation topology. 4 species have at least one representative in both SCAMP groups
