Cloning and expression of a hexose transporter gene expressed during the ripening of grape berry.
The ripening of grape (Vitis vinifera L.) is characterized by massive sugar import into the berries. The events triggering this process and the pathways of assimilate transport are still poorly known. A genomic clone Vvht1 (Vitis vinifera hexose transporter1) and the corresponding cDNA encoding a hexose transporter whose expression is induced during berry ripening have been isolated. Vvht1 is e...
متن کاملComplex Interplay of Hormonal Signals during Grape Berry Ripening.
Grape and wine production and quality is extremely dependent on the fruit ripening process. Sensory and nutritional characteristics are important aspects for consumers and their development during fruit ripening involves complex hormonal control. In this review, we explored data already published on grape ripening and compared it with the hormonal regulation of ripening of other climacteric and...
متن کاملExogenous application of pectin-derived oligosaccharides to grape berries modifies anthocyanin accumulation, composition and gene expression.
Anthocyanins are secondary metabolites synthesized in grape berry skins via the phenylpropanoid pathway, with functions ranging from skin coloration to protection against pathogens or UV light. Accumulation of these compounds is highly variable depending on genetics, environmental factors and viticultural practices. Besides their biological functions, anthocyanins improve wine quality, as a hig...
متن کاملGrape berry plasma membrane proteome analysis and its differential expression during ripening.
High purity berry plasma membranes (PMs) of Vitis vinifera L. cv. Cabernet Sauvignon were isolated by two-phase partitioning of microsome fractions at different stages of berry ripening. PM proteins resolvable by the detergent cocktail of CHAPS and ASB-14 were separated by two-dimensional electrophoresis. A total of 119 protein spots from pre-véraison berry PMs on 2-D gels detected with silver ...
متن کاملGrapes on steroids. Brassinosteroids are involved in grape berry ripening.
Fruit ripening is a unique plant developmental process with direct implications for our food supply, nutrition, and health. In contrast to climacteric fruit, where ethylene is pivotal, the hormonal control of ripening in nonclimacteric fruit, such as grape (Vitis vinifera), is poorly understood. Brassinosteroids (BRs) are steroidal hormones, essential for normal plant growth and development but...
