Gene Details:

• Gene ID: Vitvi08g01797
• Gene Symbol: VvMYB5a
• Gene Name: Transcription repressor MYB5
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• Transgenic grapevine plants with altered expression of VvMYB5a, VvMYB5b, and VvWRKY26 show phenotypic aberrations which strongly support a role for the MBWW complex in controlling different aspects of grape plant development and the accumulation of flavonoids.
• VvMYB5a and VvMYB5b are able to replace the function of PhPH4 in the control of vacuolar hyper-acidification.
• Transcriptomic analyses define roles for VvMYB5a, VvMYB5b, and VvWRKY26 in phenylpropanoid metabolism, vacuolar acidification, cell type identity, and membrane transport.
• These results indicated that VvMYB5a and VvMYB5b are functionally distinct from the anthocyanin synthesis regulator VvMYBA1, and that both proteins are functionally interchangeable with the petunia homologue PH4.
