“…Under the RDI-induced water stress, biosynthesis occurs indirectly through the production of the organic pigment carotenoids in the chloroplasts and chromoplasts. Depending on the level of the stress, abscisic acid may follow different catabolic pathways (Balint and Reynolds 2013). At a low level of water stress, abscisic acid may be catabolized by conjugation to form abscisic acid glucose ester, whereas at a high level of water stress, the oxidation pathway is preferred, which is leading to the production of catabolites (phaseic acid or dihydrophaseic acid).…”

Agriculture consumes more than two thirds of the total freshwater of the planet. This issue causes substantial conflict in freshwater allocation between agriculture and other economic sectors. Regulated deficit irrigation (RDI) is key technology because it helps to improve water use efficiency. Nonetheless, there is a lack of understanding of the mechanisms with which plants respond to RDI. In particular, little is known about how RDI might increase crop production while reducing the amount of irrigation water in real-world agriculture. In this review, we found that RDI is largely implemented through three approaches: (1) growth stage-based deficit irrigation, (2) partial root-zone irrigation, and (3) subsurface dripper irrigation. Among these, partial root-zone irrigation is the most popular and effective because many field crops and some woody crops can save irrigation water up to 20 to 30 % without or with a minimal impact on crop yield. Improved water use efficiency with RDI is mainly due to the following: (1) enhanced guard cell signal transduction network that decreases transpiration water loss, (2) optimized stomatal control that improves the photosynthesis to transpiration ratio, and (3) decreased evaporative surface areas with partial root-zone irrigation that reduces soil evaporation. The mechanisms involved in the plant response to RDI-induced water stress include the morphological traits, e.g., increased root to shoot ratio and improved nutrient uptake and recovery; physiological traits, e.g., stomatal closure, decreased leaf respiration, and maintained photosynthesis; and biochemical traits, e.g., increased signaling molecules and enhanced antioxidation enzymatic activity.

“…The relation between soil-related drought and ABA concentration in roots and shoots (either sap-transported or synthesized in leaf) is well documented, however only a few studies have linked ABA and ABA-glucose ester (GE) concentrations in berries with soil and plant water status; among them, Balint and Reynolds (2013) recently evidenced a high correlation between plant water status and ABA concentration in the berries at harvest.…”

Grapevine adaptations to water-stress are described, by focusing on soil/root interactions and root-to-shoot signaling to control both plant water relations and fruit ripening process.Root response to drought, tolerance of available rootstock germoplasm, mechanisms of embolism formation and repair in root, aquaporin control of plant water relations, and abscisic acid biosynthesis and delivery are highlighted, by reviewing recent insights coming from either (eco)physiological literature or viticultural assays addressing vineyard-soil relationships.

“…The sample collection and preparation protocols were similar with those published in Balint and Reynolds (2013a). In 2006, leaf sampling was performed on the following dates: 6 July, 20 July, 3 August, 17 August, and 31 August (6, 21, 34, 48, and 62 days postanthesis), while in 2007 sampling occurred on 5 July, 19…”

“…Measurements of extracted ABA usually reflect only a 'snapshot' of the effect of these processes and provide little information about flux, cellular, or subcellular distribution and/or the potential for rapid change (Cutler and Krochko 1999). Measurement of ABA alone is therefore insufficient, giving limited information on the total amount of ABA produced over time and on the potentially active products resulting from ABA catabolism, especially under stress conditions (Balint and Reynolds 2013a;Owen and others 2009).…”

“…Cleavage of glucose-conjugated ABA by an ABA-specific b-glucosidase, AtBG1, is a process by which bioactive ABA is synthesized in response to dehydration stress. Thus, ABA-GE could represent an inactive storage form of ABA in plants (Balint and Reynolds 2013a;Lee and others 2006). Different experimental conditions, species, and cultivars used in ABA studies have occasionally led to contradictory results (Coombe and Hale 1973;Davies and others 1997;Wheeler and others 2009).…”

The biosynthetic pathway of abscisic acid (ABA) is well known. The aim of this study was to investigate the relationship among various ABA catabolites in leaves and berries of Chardonnay grapevines grown under various irrigation regimes. An irrigation trial was set up in one vineyard, located in Niagara-on-the-Lake, ON, Canada, consisting of seven treatments: control (non-irrigated), plus three water levels (100, 50, and 25 % of estimated crop evapotranspiration) combined with two irrigation imposition times (fruit set, veraison). No irrigation occurred prior to treatment imposition. ABA, phaseic acid (PA), dihydrophaseic acid (DPA), 7 0 -hydroxy-ABA, 8 0 -hydroxy-ABA, neophaseic acid, and ABA glucose ester (ABA-GE) were quantified in leaves and berries by HPLC-MS. ABA was likely catabolized by conjugation to form ABA-GE in treatments under high levels of water deficit, while in treatments with high water status, the oxidation pathway leading to DPA or PA predominated. Concentrations of ABA and its catabolites therefore reflected vine water status, whereby the specific ABA catabolic pathways in leaves and berries were determined by water status level. Hormonal profiles suggested a direct relationship between ABA and vine water status. The concentration of ABA in Chardonnay may explain why and how white cultivars adapt to drought stress versus red cultivars.
