“…Regular exposure to DS also resulted in more production of reactive oxygen species (ROS), that is, hydroxyl radical (OH • ), superoxide anion free radical (O 2 •− ), hydrogen peroxide (H 2 O 2 ), and singlet oxygen ( 1 O 2 ) and malondialdehyde (MDA) content that causes lipid peroxidation thus less photosynthesis (Hasanuzzaman et al, 2020; Kaya et al, 2019). This can be overcome by enhanced activities of antioxidants, that is, catalase (CAT), glutathione reductase (GR), superoxide dismutase (SOD), peroxidase (POD), and ascorbate peroxidase (APX) (Khazaei & Estaji, 2020; Kumar et al, 2014). Various genes are induced at a transcriptional level; these gene products have a significant role in DS.…”

“…The application of vitamin C (ascorbic acid) has demonstrated beneficial effects in agriculture, such as reducing the effect of nickel and cadmium in barley [ 171 , 172 ], alleviating drought stress in sweet pepper [ 173 ] and Cucumber [ 174 ], and improving the qualities of apples [ 175 ]. It allows for mitigating the salinity stress and providing better growth performance in barley [ 176 ].…”

This review presents an updated scenario of findings and evolutions of encapsulation of bioactive compounds for food and agricultural applications. Many polymers have been reported as encapsulated agents, such as sodium alginate, gum Arabic, chitosan, cellulose and carboxymethylcellulose, pectin, Shellac, xanthan gum, zein, pullulan, maltodextrin, whey protein, galactomannan, modified starch, polycaprolactone, and sodium caseinate. The main encapsulation methods investigated in the study include both physical and chemical ones, such as freeze-drying, spray-drying, extrusion, coacervation, complexation, and supercritical anti-solvent drying. Consequently, in the food area, bioactive peptides, vitamins, essential oils, caffeine, plant extracts, fatty acids, flavonoids, carotenoids, and terpenes are the main compounds encapsulated. In the agricultural area, essential oils, lipids, phytotoxins, medicines, vaccines, hemoglobin, and microbial metabolites are the main compounds encapsulated. Most scientific investigations have one or more objectives, such as to improve the stability of formulated systems, increase the release time, retain and protect active properties, reduce lipid oxidation, maintain organoleptic properties, and present bioactivities even in extreme thermal, radiation, and pH conditions. Considering the increasing worldwide interest for biomolecules in modern and sustainable agriculture, encapsulation can be efficient for the formulation of biofungicides, biopesticides, bioherbicides, and biofertilizers. With this review, it is inferred that the current scenario indicates evolutions in the production methods by increasing the scales and the techno-economic feasibilities. The Technology Readiness Level (TRL) for most of the encapsulation methods is going beyond TRL 6, in which the knowledge gathered allows for having a functional prototype or a representative model of the encapsulation technologies presented in this review.

“…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. In a study on the external spraying of ASA on the leaves of a drought-stressed pepper plant, it was reported that the ASA content increased significantly as a result of the application of ASA to the peppers under drought stress (Khazaei and Estaji, 2020).…”

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.
