Abstract:

DNA binding with one zinc finger(Dof)is a kind of specific transcription factors only in plant,which are encoded by multiple genes. The N-terminus contains a highly-conserved C2-C2 single zinc finger domain consisting of 52 amino acid residues,which could bind and interact with DNA and proteins. The C-terminus is a specific transcriptional regulatory domain,its variable amino acid sequence results in the functional diversity of Dof genes. With the development of genomics and bioinformatics,Dof proteins of multiple species have been reported in recent years. The Dof genes are mainly involved in biological processes,such as plant growth and development,carbon and nitrogen metabolism,abiotic stress,and flowering regulation. Hereby we review the structural characteristics of Dof transcription factors,the number of reported Dof genes and their biological functions. We also discuss the current issues and the future prospects in studying moso bamboo flowering,aiming to provide a reference for the further study of Dof transcription factors.
