Gene Details:

• Gene ID:
• Gene Symbol: VvMADS28
• Gene Name: MADS-box 28
• Genome: Vitis vinifera PN40024.v4
• Species: Vitis vinifera

Functional Descriptions:

• In this study, we demonstrate an essential role for the grapevine MADS-box gene VvMADS28 in morphogenesis of the ovule. We found that VvMADS28 mRNA accumulated in the ovules of a seeded cultivar, ‘Red Globe’, throughout the course of ovule and seed development, especially within the integument/seed coat. In contrast, in the seedless cultivar ‘Thompson Seedless’, VvMADS28 was expressed only weakly in ovules, and this was associated with increased levels of histone H3 lysine 27 trimethylation (H3K27me3) within the VvMADS28 promoter region.
• Heterologous overexpression of VvMADS28 in transgenic tomatoes interfered with sepal development and resulted in smaller fruit but did not obviously affect seed size.
• VvMADS28 protein specifically binds to the promoter of the grapevine WUSCHEL (VvWUS) gene, suggesting that maintenance of the VvMADS28–VvMADS5 dimer and VvWUS expression homeostasis influences seed development.
• Taken together, our results provide insight into regulatory mechanisms of ovule and seed development associated with VvMADS28.
