description MYB (v-MYB avian myeloblastosis viral oncogene homolog) transcription factor (TF) family has numerous members with complex and diverse functions, which perform an integral role in regulating the plant’s response to adversity. This study used cloning to obtain a novel MYB TF gene from the diploid strawberry <i>Fragaria vesca</i>, which was given the designation <i>FvMYB44</i>. Subcellular localization results showed that the protein of FvMYB44 was a nuclear localization protein. The resistance of <i>Arabidopsis thaliana</i> to salt and low temperature stresses was greatly enhanced by the overexpression of <i>FvMYB44</i>. When subjected to salt and temperature stress, transgenic plants showed higher proline and chlorophyll concentrations and higher superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activities than wild-type (WT) and unloaded line (UL) of <i>A. thaliana</i>. In contrast, WT and UL lines had higher malondialdehyde (MDA) content and reactive oxygen species ROS (O<sub>2</sub><sup>−</sup> and H<sub>2</sub>O<sub>2</sub>) content. These findings suggest that <i>FvMYB44</i> may perform a role in controlling the response of <i>A. thaliana</i> to cold and salt stress.
