The LowSugarBerry trait phenotyped at single fruit and population levels.

Abstract

Objective: The grapevine is one of the most widely grown perennial crops worldwide. As for other species displaying clusters of small fruits, the development of single berries within a bunch is asynchronous and heterogeneous. Because of this, the study of water and solute accumulation kinetics and balance at the organ level cannot be directly extrapolated from populations of fruits. In order to have an original and reliable data sets on the accumulation of the main solutes and water in the grapevine fruits, from the onset of sugar importation to the end of phloem unloading, we analyzed the composition of populations of berries sorted according to their density and also single berry samples.

Data description: Contents in primary and secondary metabolites and cations and water during fruit ripening in a panel of varieties displaying a range of metabolic features, including genotypes able to import water at low fruit osmotic potential. These original data sets are suitable to revisit some aspects of the accumulation of main solutes and water in the grapevine fruit and/or to perform comparative studies with other fleshy fruits.
