Gene Details:

• Gene ID: Vitvi19g00270
• Gene Symbol: VvNAC72
• Gene Name: NAC domain-containing transcription factor 72
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• These results demonstrate that grapevine VvNAC72 negatively modulates detoxification of MG through repression of VvGLYI-4, and finally enhances resistance to downy mildew, at least in part, via the modulation of MG-associated ROS homeostasis through a salicylic acid-mediated defense pathway.
• Glyoxalase I-4 functions downstream of NAC72 to modulate downy mildew resistance in grapevine.
• VvNAC72 expression is induced by downy mildew, Plasmopara viticola, while the transcript level of VvGLYI-4 decreases.
• Stable overexpression of VvNAC72 in grapevine and tobacco showed a decreased expression level of VvGLYI-4 and increased content of MG and ROS, as well as stronger resistance to pathogen stress.
