VaCBF6 from Vitis amurensis is upregulated by cold stress and, when overexpressed, enhances cold tolerance in transgenic grapevine lines.
- Why it matters: Cold stress limits grapevine growth, and while CBFs are central regulators, the downstream grapevine network they control remains unclear.
- What they did: VaCBF6 was shown to localize to the nucleus, bind the VaADC promoter, and physically interact with VaADC; VaADC then interacted with VaNAC72 to regulate the VaCP17 promoter.
- The result: The VaCBF6–VaADC interaction attenuates VaCBF6-driven VaADC promoter transactivation, while the VaADC–VaNAC72 complex positively regulates VaCP17, integrating a VaCBF6–VaADC–VaNAC72 cold-tolerance module in V. amurensis.
