Abstract
- DOF proteins are plant-specific transcription factors that play vital roles in plant development and defense responses. However, DOFs have primarily been investigated in model plants, and fairly limited research has been performed on grape (Vitis vinifera). In this study, we isolated and characterized a C2-C2 zinc finger structural DOF gene, VvDOF3, from the grape cultivar Jingxiu. The VvDOF3 protein showed nuclear localization and transcriptional activation ability, indicating that it functions as a transcription factor. The VvDOF3 gene was rapidly induced by exogenous salicylic acid (SA), jasmonic acid (JA), and powdery mildew infection. Overexpression of VvDOF3 in Arabidopsis thaliana enhanced resistance to Golovinomyces cichoracearum. Expression of the SA-responsive defense-related gene PR1 and the concentration of SA were up-regulated in transgenic Arabidopsis plants overexpressing VvDOF3. Together, these data suggest that VvDOF3 functions as a transcription factor in grape and enhances powdery mildew resistance through the SA signaling pathway.
