Recently, Guo Yinshan's research team from the College of Horticulture, Shenyang Agricultural University published a paper in Horticulture Research, revealing the molecular mechanism by which the transcription factor VvWRKY5 enhances white rot resistance in grape via the jasmonic acid pathway. 

 

The study showed that VvWRKY5 can directly inhibit the expression of VvJAZ2, activate the expression of VvMYC2, and form a protein complex with VvJAZ2, thereby enhancing the inhibitory effect on the VvJAZ2 promoter and the activating effect on the VvMYC2 promoter. By regulating the JAZ-MYC module of the jasmonic acid signaling pathway, VvWRKY5 can positively regulate grape's resistance to white rot. This finding provides a theoretical basis for screening disease-resistant grape varieties and improving grape disease resistance. 

 

In summary, this study elucidates the molecular mechanism between the jasmonic acid signaling pathway and grape's resistance to white rot, which is of great significance for improving grape yield and quality.
