“…It should also be considered that different tomato cultivars exhibit different biochemical responses in relation to their specific genetic background. In previous works we have already observed that locally adapted Tuscan tomato cultivars exhibit different responses in physiological terms [53,54], as well as in the content of polyphenols and antioxidants at the fruit level [55].…”

Future climate scenarios suggest that crop plants will experience environmental changes capable of affecting their productivity. Among the most harmful environmental stresses is drought, defined as a total or partial lack of water availability. It is essential to study and understand both the damage caused by drought on crop plants and the mechanisms implemented to tolerate the stress. In this study, we focused on four cultivars of tomato, an economically important crop in the Mediterranean basin. We investigated the biochemical mechanisms of plant defense against drought by focusing on proteins specifically involved in this stress, such as osmotin, dehydrin, and aquaporin, and on proteins involved in the general stress response, such as HSP70 and cyclophilins. Since sugars are also known to act as osmoprotectants in plant cells, proteins involved in sugar metabolism (such as RuBisCO and sucrose synthase) were also analyzed. The results show crucial differences in biochemical behavior among the selected cultivars and highlight that the most tolerant tomato cultivars adopt quite specific biochemical strategies such as different accumulations of aquaporins and osmotins. The data set also suggests that RuBisCO isoforms and aquaporins can be used as markers of tolerance/susceptibility to drought stress and be used to select tomato cultivars within breeding programs.

“…192 In response to drought stress conditions, aroma enrichment was noticed in tomatoes and strawberries. 194 Water deficit conditions have improved the content of aromatic compounds, especially C13-norisoprenoids, which impart fruity character to berries and wine. 195 In apples also, root zone drying has shown positive effects on the accumulation of aroma compounds.…”

As a consequence of global climate change, acute water deficit conditions, soil salinity, and high temperature have been on the rise in their magnitude and frequency, which have been found to impact plant growth and development negatively. However, recent evidence suggests that many fruit plants that face moderate abiotic stresses can result in beneficial effects on the postharvest storage characters of the fruits. Salinity, drought, and high temperature conditions stimulate the synthesis of abscisic acid (ABA), and secondary metabolites, which are vital for fruit quality. The secondary metabolites like phenolic acids and anthocyanins that accumulate under abiotic stress conditions have antioxidant activity, and therefore, such fruits have health benefits too. It has been noticed that fruits accumulate more sugar and anthocyanins owing to upregulation of phenylpropanoid pathway enzymes. The novel information that has been generated thus far indicates that the growth environment during fruit development influences the quality components of the fruits. But the quality depends on the trade-offs between productivity, plant defense, and the frequency, duration, and intensity of stress. In this review, we capture the current knowledge of the irrigation practices for optimizing fruit production in arid and semiarid regions and enhancement in the quality of fruit with the application of exogenous ABA and identify gaps that exist in our understanding of fruit quality under abiotic stress conditions.

“…The AO treatment had the lowest ASA content, as the application of AO alone reduced the ASA content compared to the control (Figure 6B). Conti et al (2022), in a study they conducted with 12 different tomato cultivars exposed to drought stress, stated that drought stress caused an increase in the ASA content of some cultivars while a decrease in some cultivars. The fact that ASA content was found to be the highest in AO+D application in the current study can be considered as one of the important signs that AO has positive effects on the antioxidant system of maize seedlings under drought stress.…”

The negative effects of drought stress, which is the most effective type of stress on the yield loss of crops with a rate of 26% among abiotic stresses, are increasing day by day with global warming. The purpose of the study is to find out if Acetone O-(4 chlorophenylsulfonyl) oxime (AO) has positive effects on the metabolism of maize seedlings under drought or not. The following experimental setup was established: 18 hours distilled water Control (C), 6 hours 0.66 mM AO+12 hours distilled water (AO), 6 hours distilled water+12 hours 3% PEG (D), and 6 hours 0.66 mM AO+12 hours 3% PEG (AO+D). While ABA content decreased in AO application compared to control, it was determined that ABA decreased in AO+D application compared to D. While a difference could not be determined between AO by control and between D by AO+D applications on RWC content, it was observed that stress significantly reduced in RWC. It was determined that AO increased the Photosynthetic pigment content in the AO+D compared to the D. It was determined that AO reduced MDA and H2O2 content by regulating the activities of antioxidant system enzymes. It was observed that the proline content increased in AO application compared to control and in AO+D application compared to D. While ASA content decreased in AO application compared to control, it was determined that ASA content increased in AO+D application compared to D. Significant fluctuations in the contents of phenolic substances were determined. As a result, the pre-application of AO to maize under drought stress may prevent the formation of radicals, and this situation is thought to be due to the antioxidative properties of AO.
