Drought is one of the main abiotic stresses affecting plant growth and development. Reduced yield quality are primarily caused by reductions in photosynthesis, mineral uptake, metabolic disorders, damages from increased production reactive oxygen species, many other disruptions. Plants utilize drought resistance mechanisms as a defense strategy, systems’ activation dependent upon several factors, including genotype, onthogenesis phase, intensity duration, season which occurs.

Plants treated with As showed considerable decline growth attributes like height, fresh dry weight plant. Arsenic reduced content δ-amino livulenic (δ-ALA), glutamate 1-semialdehyde (GSA), total chlorophylls carotenoids, more reduction evident at higher (10 concentrations, however supplied JA alleviated extent. mediated photosynthetic gas exchange parameters, Fv/Fm (PSII activity) Rubisco activity was by exogenous treatment JA. caused oxidative damage which as increased lipid peroxidation, lipoxygenase hydrogen peroxide concentrations however, declined these parameters. Treatment improved nitrate reductase synthase under unstressed conditions also triggered stress. Activity antioxidant enzymes assayed due stress, supplementation further increase their activities.

A greenhouse trial was conducted in Southern Italy to examine the effects of foliar applications two substances, methyl-jasmonate (MeJA) and a zeolite, on harvest post-harvest performance hydroponically grown baby leaf genotypes (leafy chicory ‘Cicoria costa rossa’; kale ‘Cavolo nero’). MeJA is phyto-hormone primarily studied for fruit applications, while zeolite typically used pest disease biological control. (Sigma-Aldrich Merck KGaA, Darmstadt, Germany), commercial (Big-Zeo, Agricola Internazionale s.r.l., Pisa, Italy) (BigZeo) were sprayed twice at second fourth true stages (BigZeo, 5 kg ha−1; MeJA, 250 µM). Bio-physiological (yield, dry matter DM, chlorophyll CHL, weight loss WL) qualitative (nitrate, carotenoids, phenols, flavonoids, anthocyanins, antioxidant activity) traits evaluated both raw fresh-cut (7 day-cold-stored) products. Treatments did not significantly affect yield (1.0 m−2), plant responses substances concerning other genotype-dependent. enhanced greenness (CHL), texture (DM), activity (by increasing carotenoids flavonoids) chicory. In contrast, improved greenness, texture, phenols), reduced nitrate kale. (2.2 g 100 g−1 f.w., average). After 7 days storage, MeJA-treated zeolite-treated exhibited textural nutritional quality.

Drought stress poses a significant challenge to agriculture sustainability across the globe. negatively affects plant growth and productivity intensity of this serious abiotic is continuously increasing which threat Different measures are being used mitigate adverse impacts drought stress. Among these measures, application exogenous osmolytes hormones considered an important way drought. Recently, jasmonic acid (JA) has emerged as excellent hormone improve tolerance owing its involvement in different physiological biochemical processes. Jasmonic improves membrane stability water relations, nutrient uptake, osmolyte accumulation, antioxidant activities that can counter toxic effects It also contributes signaling pathways, i.e., genes network, stress-responsive proteins, intermediates, enzymes protect plants from Further, JA protects maintains integrity cells by up-regulating defense system accumulation. In review, we have documented protective role under The various mechanisms inducing discussed research gaps identified. This review will help readers learn more about it provide new knowledge develop plants.

Common agronomic practices such as stem topping, side branch removal, and girdling can induce wound priming, mediated by jasmonic acid (JA). Low light conditions during greenhouse tomato production make the leaves more sensitive to application of exogenous sugar, which is perceived a "danger" in accordance with concept "Sweet Immunity". Consequently, source–sink balances are altered, leading remobilization starch reserves enabling redirection carbon toward developing fruits, thereby increasing yield fruit quality. Similarities drawn mobilization fructans following defoliation fodder grasses (wounding) fructan under terminal drought heat stress wheat rice (microwounding, cellular leakage). A central role for JA signaling evident all these processes, closely intertwining sugar pathways. Therefore, signaling, associated wounding priming events, offers numerous opportunities alter across broader spectrum agricultural horticultural crops, instance, through or combination. This may entail reconfiguring reversing phloem connections, potentially an enhanced product Such processes also disengage growth–defense trade-off plants.
