Gene Details:

• Gene ID: Vitvi10g02328
• Gene Symbol: VvBBX44VvBBX32
• Gene Name: Vitis vinifera B-box protein 44
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• Our previous work has shown that Vitis vinifera B-box protein 44 (VvBBX44) inhibits anthocyanin synthesis and represses VvHY5 expression in grape calli.
• Found that loss of VvBBX44 function resulted in increased anthocyanin accumulation in grapevine callus.
• VvBBX44 directly represses VvMYBA1, which activates VvBBX44. VvMYBA1, but not VvBBX44, directly modulates the expression of grape UDP flavonoid 3-O-glucosyltransferase (VvUFGT).
• VvBBX44 and VvMYBA1 form a regulatory feedback loop to balance anthocyanin biosynthesis in grape.
