| Summary: | Apple replant disease (ARD) caused by the pathogen Fusarium solani is a destructive disease in apple planting areas worldwide, which leads to the decline of apple quality and yield. WRKY transcription factors are involved in the process of plants responding to various environmental stresses, but the function of WRKY TFs in ARD is unclear. In this study, the expression of MdWRKY20 was significantly increased after infection of apple rootstock 'M9T337' with F. solani. Transgenic analysis showed that the resistance of apple callus and Arabidopsis to F. solani increased after overexpression of MdWRKY20. Ectopic expression of MdWRKY20 also significantly enhanced antioxidant capacity in Arabidopsis under treatment with F. solani. Then, MdWRKY20 was found to bind directly to the W-box II of the MdPR1 promoter and significantly promoted its expression. In summary, MdWRKY20 plays a positive role in regulating the resistance of apples to F. solani. |
