Phylogenetic analysis of TCP transcription factors from Chrysanthemum indicum, Arabidopsis thaliana, Oryza sativa and Populus trichocarpa. ClustalW was applied for the alignment of protein sequences. Maximum-likelihood method with 1000 bootstrap replicates was utilized to construct the phylogenetic tree in MEGA X software. Different colors represent different sub-classes in the TCP gene family. The TCPs from Chrysanthemum indicum, Arabidopsis thaliana, Oryza sativa and Populus trichocarpa are marked with blue star, green square, red circle and yellow triangle, respectively
