Interpretive Summary:

Technical Abstract: Water scarcity threatens crop production in dry growing regions across the globe. Changing climatic conditions could exacerbate this situation, as more intense and prolonged drought events are predicted for many regions. Grapevines are commonly grown in Mediterranean-like regions that are characterized by long, dry summers and prone to extended periods of drought. Here we review recent literature focused on the grapevine genome responses to drought stress ranging from mild to severe. Recent advances in grapevine have demonstrated that a large number of genes are involved in plant drought responses. There is strong evidence that ABA plays a key role in various aspects of metabolism in the overall response. The identification of genes that lead to the stress-induced production of ABA and the perception of this signal is important in understanding stomatal regulation under mild water deficit. However, further work is required to fully elucidate the signal transduction and transcriptional regulation of these genes under stress conditions, especially at the protein level.
