520 |a DNA-binding with one finger (Dof) domain proteins are a multigene family of plant-specific transcription factors involved in numerous aspects of plant growth and development. Here, we report a genome-wide search for Solanum tuberosum Dof (StDof) genes and their expression profiles at various developmental stages and in response to various abiotic stresses. In addition, a complete overview of Dof gene family in potato is presented, including the gene structures, chromosomal locations, cis-regulatory elements, conserved protein domains, and phylogenetic inferences. Based on the genome-wide analysis, we identified 35 full-length protein-coding StDof genes, unevenly distributed on 10 chromosomes. Phylogenetic analysis with Dof members from diverse plant species showed that StDof genes can be classified into four subgroups (StDofI, II, III, and IV). qPCR expression analysis of StDof gene transcripts showed the distinct expression patterns of StDof genes in various potato organs, and tuber developmental stages analyzed. Many StDof genes were upregulated in response to drought, salinity, and ABA treatments. Overall, the StDof gene expression pattern and the number of over-represented cis-acting elements in the promoter regions of the StDof genes indicate that most of the StDof genes have redundant functions. The detailed genomic information and expression profiles of the StDof gene homologs in the present study provide opportunities for functional analyses to unravel the genes' exact role in plant growth and development as well as in abiotic stress tolerance
