The DNA binding with one finger (Dof) protein is a kind of plant specific transcription factors, which usually has 200-400 amino acids and two main domains. The Nterminal of the Dof protein was highly conserved and could interact with DNA and protein. The Cterminal which has variable amino acid sequence is the specific transcriptional regulatory domain of Dof gene. Recently, it has been reported that Dof proteins are involved in the growth and development of different plants as transcriptional activators or repressors. Until now, with the rapid development of genome sequencing technology, a large number of Dof genes have been identified from different species. Here, the structural features, member identification in whole genome, interaction proteins, as well as the progress of biological function of Dof family members from different plants in recent years were summarized, and we hope this work would be helpful in the further study of Dof transcription factors.
