Gene Details:

• Gene ID: Vitvi06g00771
• Gene Symbol: VvPRX4
• Gene Name: Peroxidase 4
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• These were VvPRX1, VvPRX4, and VvPRX72, which encode PRX genes involved in the final stages of lignin biosynthesis.
• Transgenic grapevine plants overexpressing VlbZIP30 exhibited lignin deposition (mainly G and S monomers) in the stem secondary xylem under control conditions, which resulted from the upregulated expression of VvPRX4 and VvPRX72.
• VlbZIP30 regulates the expression of lignin biosynthetic (VvPRX N1, VvPRX4, and VvPRX72) and drought-responsive (VvNAC17) genes through binding of the G-box cis-element in their promoters, thus promoting lignin biosynthesis and improving drought resistance in grapevine.
