Abstract

This dataset contains quantitative metabolite profiles measured in latent buds of Vitis vinifera L. cv. Cabernet Sauvignon across the annual dormancy cycle. The dataset is provided as a comma-separated values (CSV) file and includes 35 biological observations distributed across calendar months, with each row corresponding to an individual biological replicate. A total of 41 metabolites are reported, covering central carbon metabolism, including sugars, sugar phosphates, organic acids, and sugar alcohols. Metabolites quantified include trehalose-6-phosphate, sucrose-6-phosphate, hexose phosphates, glycolytic and tricarboxylic acid (TCA) cycle intermediates, soluble sugars (e.g., sucrose, glucose, fructose), raffinose family oligosaccharides, and polyols. Concentration values are reported as absolute metabolite abundances as determined by targeted metabolite profiling, following the analytical protocols described in the associated research article on seasonal regulation of dormancy in grapevine buds. The dataset is intended to support reuse in studies of plant dormancy, seasonal metabolism, carbohydrate dynamics, and comparative analyses across perennial species or cultivars. It can also be integrated with transcriptomic, physiological, or environmental datasets for systems-level analyses of bud dormancy regulation. The data are observational, involve no human or animal subjects, and raise no ethical or legal concerns. All data are released for open reuse under the terms specified by the repository.
