Gene Details:

• Gene ID: Vitvi08g02245
• Gene Symbol: VvCAX3
• Gene Name: Vacuolar cation/H+ exchanger 3
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• The grapevine VvCAX3 is a cation/H+ exchanger involved in vacuolar Ca2+ homeostasis.
• The truncated VvCAX3 was further shown to be involved in the transport of Na+, Li+, Mn2+ and Cu2+ in yeast cells. Subcellular localization studies using fluorescently tagged proteins confirmed VvCAX3 as a tonoplast transporter.
• VvCAX3 may be an interesting target towards the development of strategies for enhancement of grape berry properties.
• The grapevine VvCAX3 mediates calcium transport in the vacuole and is mostly expressed in green grape berries and upregulated by Ca 2+ , Na + and methyl jasmonate.
• The results obtained add new insights on the mechanisms involved in calcium homeostasis and intracellular compartmentation in grapevine, and indicate that VvCAX3 may be an interesting target towards the development of strategies for enhancement of grape berry properties.
