Phylogenetic analysis of the selected plant GRF proteins. Phylogenetic tree was constructed by MEGA5 with neighbor-joining method. Two groups were shown as ε group and non-ε group from alignments of 132 GRF amino acid sequences from G. herbaceum (17), G. arboreum (17), G. hirsutum (31), G. raimondii (17), Arabidopsis (13), rice (8), P. trichocarpa (14), B. distachyon (7), and foxtail millet (8)
