GhDof1.7, a Dof Transcription Factor, Plays Positive Regulatory Role under Salinity Stress in Upland Cotton.

ABSTRACT: Salt stress is a major abiotic stressor that can severely limit plant growth, distribution, and crop yield. DNA-binding with one finger (Dof) is a plant-specific transcription factor that plays a crucial role in plant growth, development, and stress response. In this study, the function of a Dof transcription factor, GhDof1.7, was investigated in upland cotton. The GhDof1.7 gene has a coding sequence length of 759 base pairs, encoding 252 amino acids, and is mainly expressed in roots, stems, leaves, and inflorescences. Salt and abscisic acid (ABA) treatments significantly induced the expression of GhDof1.7. The presence of GhDof1.7 in Arabidopsis may have resulted in potential improvements in salt tolerance, as suggested by a decrease in H₂O
