Cuticle and skin cell walls have common and unique roles in grape …
2021年8月1日 · These results showed that both cuticle and skin cell walls contribute to the mechanical properties of grape berries and to their splitting resistance. The results also suggest that the two...
Grape Berry Vacuole: A Complex and Heterogeneous Membrane …
Vacuoles fulfill highly specialized functions depending on cell type and tissue and plant developmental stage. This complex and dynamic organelle is the main reservoir of grape berry cells, playing a major role during fruit development and ripening.
Anatomical berry characteristics during the development of grape ...
2021年7月1日 · The cell division and cell expansion during fruit development are the key parameters affecting the final shape of the fruit (Gillaspy et al., 1993). Studies have shown that cell division activity is high for the first 10–14 days of fruit development.
Changes in Cell Wall Composition during Ripening of Grape Berries
1998年4月20日 · The most significant change in the composition of grape cell walls during ripening was the dramatic decrease in the amount of (1→4)-linked Galp residues (Tables (TablesII II and III).
Black Corinth is the only truly seedless grape (a parthenocarpic fruit that grows without fertilization of the flower). It is occasionally sold as a table grape and has very small berries (frequently called the Champagne grape). The commercially available dried currant is …
Pectins, Hemicelluloses and Celluloses Show Specific Dynamics in …
2016年4月19日 · Using this multifaceted approach, we provided a detailed profile of cell wall modifications in grape berry skin during ripening, highlighting differences between the internal and the external side of the skin.
Grape Small Auxin Upregulated RNA (SAUR) 041 Is a Candidate …
2024年10月30日 · As the largest family of auxin early response genes, SAUR (small auxin upregulated RNA) plays an important role in the growth and development of plants. Berry size is one of the important factors that determine grape quality. However, the SAUR gene family’s function in berry size of grape has not been studied systematically.
Physical, Anatomical, and Biochemical Composition of Skins Cell …
2021年10月18日 · During the maturation period, the grape skins of the two cultivars appear different in their structure and composition. Chardonnay is characterized by higher relative humidity (RH) and level of VvPG1 expression, lower disease incidence and penetrometry values, and thicker cell walls than Pinot noir skins.
Cellular expansion and gene expression in the developing grape
2008年4月18日 · Expression profiles of genes involved in cell wall metabolism and water transport were compared with changes in grape (Vitis vinifera L.) berry growth, basic chemical composition, and the shape, size, and wall thickness of cells within tissues of the berry pericarp.
Improved maceration techniques to study the fruit vascular anatomy of grape
2023年6月1日 · We developed methods to isolate grape vascular bundles from flesh cells and isolate individual xylem cells using improved maceration. We also used these improved techniques to determine the structural characteristics of individual vessel cells, including their longitudinal and three-dimensional arrangement and vessel-to-vessel pit connections.
