Gene Details:

• Gene ID: Vitvi16g04340
• Gene Symbol: VvCBF4
• Gene Name: C-repeat binding protein 4
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• To overcome such production losses, a recently identified grapevine C-repeat binding factor (CBF) gene, VvCBF4, was overexpressed in grape vine cv.
• The Vitis vinifera C-repeat binding protein 4 (VvCBF4) transcriptional factor enhances freezing tolerance in wine grape.
• The overexpression of the VvCBF4 gene is shown to impart a reduced growth phenotype as well as confer improved freezing survival in nonacclimated vines, similar to the effects of CBF overexpression in Arabidopsis and other species.
• Putative VvCBF4-regulon targets included genes with functions in cell wall structure, lipid metabolism, epicuticular wax formation and stress-responses suggesting that the observed cold tolerance and dwarf phenotypes are the result of a complex network of diverse functional determinants.
