Phylogenetic and evolutionary relationship of IDD gene family in cotton and other plant species. Full-length protein sequences of IDD genes were used for analysis. Phylogenetic tree of IDD genes was constructed using MEGA 7.0 software. To identify IDD family genes, prefixes At, Ga, Gh, Gr, Os, Tc, Sm, and Pp, presented A. thaliana, G. arboreum, G. hirsutum, G. raimondii, O. sativa, Theobroma cacao, S. moellendorffii and P. patens, respectively. Different groups of IDD genes are emphasized in different colors
