Gene Details:

• Gene ID: Vitvi15g00938
• Gene Symbol: VvMybPA1
• Gene Name: MYB transcription factor PA1
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• A previous study has already identified VvMybPA1 as the first transcription factor involved in the regulation of the proanthocyanidin pathway during seed development in grapevine.
• Ectopic expression of either VvMybPA1 or VvMybPA2 in grapevine hairy roots induced qualitative and quantitative changes of the proanthocyanidin profiles.
• High-throughput transcriptomic analyses of transformed grapevine organs identified a large set of putative targets of the VvMybPA1 and VvMybPA2 transcription factors.
• The Grapevine Transcription Factor VvMybPA1 Regulates Proanthocyanidin Synthesis during Fruit Development.
• A first result emerged from this study, where overexpression of VvMybPA2 resulted in the accumulation of VvMybPA1 transcripts, suggesting that VvMybPA2 signal acts upstream to VvMybPA1.
