VvGRX28 interacting with VvZNF10 modulates cold tolerance via eliminating excessive ROS in grapevine

Glutaredoxins (GRXs) are small oxidoreductases that play a crucial role in response to abiotic stress. Although the GRX gene family has been characterized in several species, the knowledge of their evolution relationship, diversification and function in grape are still limited. In this study, 32 VvGRX genes were identified and clustered into CC-, CGFS-, GRL- and CPYC-type categories. The structure and motifs of VvGRXs were similar in genes clustered into close branches, indicating highly conserv
