title: Dof domain proteins: plant-specific transcription factors associated with diverse phenomena unique to plants.
abstract: Dof (DNA-binding with one finger) domain proteins are plant-specific transcription factors with a highly conserved DNA-binding domain, which presumably includes a single C(2)-C(2) zinc finger. During the past decade, numerous Dof domain proteins have been identified in both monocots and dicots including maize, barley, wheat, rice, tobacco, Arabidopsis, pumpkin, potato, and pea. Biochemical, molecular biological and molecular genetic analyses revealed that Dof domain proteins function as a transcriptional activator or a repressor involved in diverse plant-specific biological processes. Although more physiological roles of Dof domain proteins would be elucidated in future because of numerous Dof domain proteins in plants, it is already evident that the Dof domain proteins play critical roles as transcriptional regulators in plant growth and development. Here I summarize our current knowledge about Dof domain proteins.
