Gene Details:

• Gene ID: Vitvi08g02330
• Gene Symbol: VvSUN
• Gene Name: protein IQ-DOMAIN
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• VvSUN may act in the auxin pathway to regulate fruit shape in grape,VvSUN, which belongs to the SUN/IQ67-DOMAIN (IQD) family, localizes to the plasma membrane and chloroplast and may be involved in controlling fruit shape through auxin.
• Functional analyses illustrated that VvSUN gene overexpression in tomato and tobacco plants changed fruit/pod shape.
• The VvSUN promoter directly bound to VvARF6 in yeast and activated ß-glucuronidase (GUS) activity by indole-3-acetic acid (IAA) treatments in grapevine leaves, indicating that VvSUN functions are in coordination with auxin.
• It is possible that VvSUN acts as a hub gene, altering cellular auxin levels and the plant hormone signal transduction pathway, which plays a role in cell division patterns, leading to anisotropic growth of the ovary and, ultimately, an elongated fruit shape.
