  • Phloem unloading is thought to switch from a symplastic route to an apoplastic route at the beginning of ripening in grape berries and some other fleshy fruits. [...] Key Method We modified a method developed for tomato fruit to extract apoplastic sap from grape berries and measured the changes in apoplastic and vacuolar pH, soluble sugars, organic acids, and potassium in ripening berries of Vitis vinifera ‘Merlot’ and V. labruscana ‘Concord’. Solute accumulation varied by genotype, compartment, and chemical…Expand Abstract
