Fig. 4From: Genome-wide analysis of Dof transcription factors and their response to cold stress in rice (Oryza sativa L.)Phylogenetic tree of DOF proteins from barley, wheat, stiff brome, and rice. Full-length protein sequences were aligned using ClustalX, and a joint phylogenetic tree was generated in MEGA 6.0 using the maximum likelihood method. Rice DOFs are indicated in yellowBack to article page
