Fig. 5

The maximum-likelihood (ML) phylogenetic tree built by MCTPs from 28 plant species and four out-group species and corresponding domain structure. Abbreviation of species names in Table S1 were used as prefixes in the protein names to denote the species. Additionally, MCTP members belonging to different lineages or/and species were marked in the colors same as those in Figure S2. The phylogenetic tree could be categorized into five clades and branches of different clades were marked with different colors. Blue, red, green, purple and yellow branch represented Clade I to V, respectively. TM region topology across MCTPs were also showed, red squares represented TM regions, blue diamonds represented C2 domains
