Gene Details:

• Gene ID: Vitvi02g01024
• Gene Symbol: VvMYBA2w
• Gene Name: MYB transcription factor 2-white allele
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• The role of VvMYBA2r and VvMYBA2w alleles of the MYBA2 locus in the regulation of anthocyanin biosynthesis for molecular breeding of grape (Vitis spp.) skin coloration.
• The ectopic expression of VvMYBA2w inactivated the expression of anthocyanin biosynthetic genes and could not cause obvious phenotypic modulation in transgenic tobacco.
• CA dinucleotide deletion within VvMYBA2w shortens its C-terminal transcriptional activation region and disrupts its transcriptional activation activity.
• This study provides insight into the roles of VvMYBA2r and VvMYBA2w alleles and lays the foundation for the molecular breeding of grape varieties with different skin colour.
