Abiotic-Stress Application, Global Berry Proteome Profiling, and Cold-Stress Tolerance in Transformed Winegrape (Vitis vinifera L.).
Wine grape (Vitis vinifera L.) was domesticated more than 7,000 years ago and continues to provide one of the most important fruit crops worldwide. V. vinifera cultivars are moderately sensitive to salt and temperature stresses, whereas moderate water deficit stress results in minimal loss in berry …
