Phylogenetic tree of PMEs. a Phylogenetic tree of PMEs from 11 species. The phylogenetic tree is based on a sequence alignment of the C-terminal PME domains of 751 PMEs protein sequences from 11 genomes, G. hirsutum, G. arboreum, G. raimondii, A. thaliana, O. sativa, V. vinifera, P. trichocarpa, G. max, T. cacao, C. papaya, and R. communis. The PME proteins are grouped into 10 distinct clades (I–X). b Phylogenetic tree of PME domain containing proteins from G. raimondii, G. arboreum, and G. hirsutum. The phylogenetic tree is based on a sequence alignment of the C-terminal PME domains of 293 PME protein sequences from three genomes, G. arboreum, G. raimondii, and G. hirsutum. The tree was generated with MEGA 5.1 using the neighbor-joining method. Bootstrap values from 1000 replicates are indicated at each node. The PME proteins are grouped into 8 distinct clades (I–VIII)
