The DOF(DNA binding with one finger) genes represent a class of plant-specific transcription factors,which play a crucial role in various stages of plant growth and development,as well as in response to environmental stresses.In this study,61 DOF transcription factors were identified from the peanut genome, and a systematic bioinformatics analysis was conducted.The results indicated that the members of the DOF family are distributed across all 20 chromosomes, but their distribution is uneven.Amino acid sequence alignment revealed that DOF proteins primarily contain 10 types of Motif sequences.Analysis of tissue expression patterns demonstrated that some members including Ah DOF4 exhibit strong tissue specificity.Additionally, AhDOF3、AhDOF31、AhDOF46 showed varying degrees of positive responses to drought stress.In this study,it is demonstrated that peanut DOF protein sequences showed both similarity and conservation,while their regulatory mechanisms are diverse.Consequently,this research provides a theoretical foundation for further investigations into the functions of related genes and their potential application in breeding.
