title: Dof transcription factors in carrot: genome-wide analysis and their response to abiotic stress.
abstract: OBJECTIVE
  The DNA-binding one zinc finger (Dof) family transcription factors (TF) are involved in stress response. Dof TFs in carrot were identified and the responses of DcDof genes to abiotic stresses were analyzed.
  
  
  RESULTS
  46 DcDofs in carrot were identified from carrot genome database. Based on the conserved domain in Dof TF family of Arabidopsis thaliana, the DcDof TFs were divided into four classes, named class A, B, C and D. Carrot and Arabidopsis shared most motifs in the same subgroup. Real-time quantification PCR analysis showed tissue-specific expression patterns in DcDofs. DcDofs from eight subgroups responded to four abiotic stress treatments.
  
  
  CONCLUSIONS
  The expression profiles were different with the abiotic stresses changed, indicating complicated regulatory mechanisms in Dof TF family in higher plant, and the response mechanisms of Dof genes may be influenced by different plant species.
