[EN] This scientific paper delves into the effects of water stress on grapevines, specifically
focusing on gene expression and polyphenol production. We conducted a controlled greenhouse
experiment with three hydric conditions and analyzed the expression of genes related to polyphenol biosynthesis. Our results revealed significant differences in the expression of ABCC1, a gene
linked to anthocyanin metabolism, under different irrigation treatments. These findings highlight
the importance of anthocyanins in grapevine responses to abiotic stresses. By integrating genomics,
metabolomics, and systems biology, this study contributes to our understanding of grapevine physiology under water stress conditions and offers insights into developing sensor technologies for
real-world applications in viticulture.
