Gene Details:

• Gene ID: Vitvi03g00519
• Gene Symbol: VvPUB26
• Gene Name: U-box domain-containing protein 26
• Genome: grape genome database
• Species: Vitis vinifera

Functional Descriptions:

• Ubiquitin ligase VvPUB26 in grapevine promotes proanthocyanidin synthesis and resistance to powdery mildew.
• Overexpression of VvPUB26 in grapes leads to a significant increase in PAs content, whereas interfering with VvPUB26 has the opposite effect.
• Overexpression of VvPUB26 in transgenic grapevines enhances defense against powdery mildew while interfering with VvPUB26 results in increased susceptibility to the pathogen.
• Our results unveil a regulatory module involving VvPUB26-VvWRKY24-VvDFR/VvLAR that plays a fundamental role in governing PAs biosynthesis in grapevines.
