Phylogenetic relationships among J. curcas, A. thaliana, and R. communis Dof proteins. The neighbor-joining tree was created using the MEGA6.0 program (bootstrap value set at 1000). Thirty-six (36) AtDof proteins marked with black pentacle, 24 JcDof proteins marked with yellow pentacle, and 21RcDof proteins marked with red pentacle. The resulting phylogenetic tree was clustered into three major groups (A, B, and C), which were supported by a bootstrap value over 80%. The Dof proteins in Group C were further divided into two sub-groups, C1 and C2, supported by a bootstrap value over 40%. The detailed information of all the Dof proteins is listed in Supplementary Table S2.
