Functional characterisation of three members of the Vitis vinifera L. carotenoid cleavage dioxygenase gene family
BackgroundIn plants, carotenoids serve as the precursors to C13-norisoprenoids, a group of apocarotenoid compounds with diverse biological functions. Enzymatic cleavage of carotenoids catalysed byExpand
The grapevine polygalacturonase-inhibiting protein (VvPGIP1) reduces Botrytis cinerea susceptibility in transgenic tobacco and differentially inhibits fungal polygalacturonases
Polygalacturonase-inhibiting proteins (PGIPs) selectively inhibit polygalacturonases (PGs) secreted by invading plant pathogenic fungi. PGIPs display differential inhibition towards PGs fromExpand
Optimisation of an HPLC method for the simultaneous quantification of the major sugars and organic acids in grapevine berries.
A high performance liquid chromatographic method was developed to profile major sugars and organic acids in grapevine berries. Sugars and organic acids in grapevine berries were extracted byExpand
High-performance liquid chromatography profiling of the major carotenoids in Arabidopsis thaliana leaf tissue.
Carotenoids are extremely sensitive to a variety of physico-chemical attacks which may have a profound effect on their characteristic properties, thereby influencing the accurate identification andExpand
The genes and enzymes of the carotenoid metabolic pathway in Vitis vinifera L.
BackgroundCarotenoids are a heterogeneous group of plant isoprenoids primarily involved in photosynthesis. In plants the cleavage of carotenoids leads to the formation of the phytohormones abscisicExpand
Genetically tailored grapevines for the wine industry.
Grapevine biotechnology is one of the most promising developments in the global wine industry, which is increasingly faced with conflicting demands from markets, consumers and environmentalists. InExpand
Grapevine Plasticity in Response to an Altered Microclimate: Sauvignon Blanc Modulates Specific Metabolites in Response to Increased Berry Exposure1
Grapevine responds to increased exposure in the bunch zone by up-regulating photoprotective carotenoids in the early developmental stages and volatile terpenoids in the later ripening stages of theExpand
Field-Grown Grapevine Berries Use Carotenoids and the Associated Xanthophyll Cycles to Acclimate to UV Exposure Differentially in High and Low Light (Shade) Conditions
Light quantity and quality modulate grapevine development and influence berry metabolic processes. Here we studied light as an information signal for developing and ripening grape berries. A VitisExpand
Metabolic engineering of Saccharomyces cerevisiae for the synthesis of the wine-related antioxidant resveratrol.
The stilbene resveratrol is a stress metabolite produced by Vitis vinifera grapevines during fungal infection, wounding or UV radiation. Resveratrol is synthesised particularly in the skins of grapeExpand
Vv-AMP1, a ripening induced peptide from Vitis vinifera shows strong antifungal activity
BackgroundLatest research shows that small antimicrobial peptides play a role in the innate defense system of plants. These peptides typically contribute to preformed defense by developing protectiveExpand
