Genome-wide analysis and comparison of the DNA-binding one zinc finger gene family in diploid and tetraploid cotton (Gossypium)

The Dof (DNA-binding one zinc finger) transcription factor family is a representative of plant-specific classes of transcription factors. In this study, we performed a genome-wide screening and characterization of the Dof gene family within two tetraploid species Gossypium barbadense, Gossypium hirsutum, and two diploid species Gossypium arboreum, Gossypium raimondii. 115, 116, 55 and 56 Dof genes were identified respectively and all of the...
