Microarray analyses of salt and water stressed ‘Cabernet Sauvi-gnon’ grapevines demonstrated that more than 2000 genes were differentially expressed, and expression was influenced by both drought and ABA [108]. Significant differences as well as com-mon attributes were observed in gene response to varying stressfactors. These included transcription factors, genes involved in signal transduction and carbohydrate metabolism, which may ulti-mately contribute to enhanced abiotic stress tolerance [109]. Waterdeficit imposed by drought appeared to have a more severe effect than that imposed from salinity. Differences in protein expression were observed between V. vinifera cultivars Chardonnay and Caber-net Sauvignon exposed to drought and salinity stress. Decrease in growth parameters were correlated with corresponding reductionsin the amounts of proteins involved in photosynthesis
