Combining "omics" with molecular, biochemical and physiological analyses as an integrated effort to validate novel and easy-to-implement drought mitigation strategies in grapevine while reducing water use
Water-deficit stress is a common threat to the Portuguese wine-production sector. Identifying mechanisms underlying grapevine responses to this water-deficit stress has the potential of opening new avenues for the development of practical strategies to tackle its negative impact on grape berry productivity and/or quality. The osmoprotective nature of polyols and the abiotic-stress signalling function of abscisic acid led us to propose this work aimed at developing/validating easy-to-implement strategies for mitigating grapevine’s drought stress symptoms while maintaining berry quality and reducing water use, in the form of exogenous application of polyols or abscisic acid. Our proposed combination of omics approaches with plant physiology, biochemistry and molecular biology will deeply scrutinize how these strategies may positively impact productivity and key berry quality- and abiotic stress-related and wine sensorial traits, while revealing new quality- and stress-related biomarkers.
