Firmness is an essential quality parameter of table grapes (Vitis vinifera) for consumers, with grape bunches that contains soft berries less preferred, resulting in a reduction in the market price. The softening of grape berries has been commonly associated with cell walls, especially the disassembly of pectic polysaccharides. However, the process of berry softening is not completely understood. To investigate the softening process of grape berries, we compared the Thompson Seedless variety, which suffers significant economic losses due to fruit softening, and NN107, a new variety with a significantly higher level of berry firmness. The composition of the cell wall during the berry development of these two grape varieties was compared. NN107 berries had a greater amount of calcium and uronic acids in the cell wall material than Thompson Seedless grapes, suggesting a special role for calcium bridge formation in NN107. Additionally, polyacrylamide carbohydrate electrophoresis (PACE) analysis suggested differences between these varieties in pectin structure. Thompson Seedless grapes showed increased pectolyase hydrolysable site dynamics in the cell wall material and higher polygalacturonase activity than NN107. Immunohistochemistry focusing on the pectin structure confirmed the roles of both calcium bridge formation and cell wall integrity as they relate to a firmer grape berry phenotype. 相似文献

Low temperature storage is widely used to maintain the quality of postharvest fruit and extend their shelf-life. In this study, changes in specific metabolites and protein expression profiles of grape berries under cold storage were investigated by liquid chromatography and proteomic studies, respectively. During cold storage, total soluble solids and reducing sugars accumulation was accompanied by a decline in organic acids and phenols contents. A comparative analysis of the proteomes of grape berries during cold storage was performed using a two-dimensional electrophoresis (2-DE) proteomic approach. Seventy-nine differentially regulated proteins during cold storage were successfully identified by matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry, and classified into eight main categories based on their biological function. Down-regulation of proteins associated with glycolysis and the Krebs cycle, and up-regulation of cell wall polysaccharide degradation-related enzymes provided molecular evidence that soluble sugar and carbohydrate metabolism play a crucial role in postharvest regulation. In addition, cold storage increased the expression abundance of several stress related proteins such as heat shock proteins, proteasome and antioxidant enzymes, suggesting a physiological adaptation to low temperature was induced in grape berries. This study contributes to a better understanding of the cellular events in grape berries under cold storage and provides potentially useful information for maintaining fruit quality and minimizing postharvest losses. 相似文献
