Glutathione (GSH; γ-glutamyl-cysteinyl-glycine), a low-molecular-weight thiol, is the most pivotal metabolite involved in antioxidative defense system of plants. The modulation GSH on plant response to environmental stresses could be illustrated through key pathways such as reactive oxygen species (ROS) scavenging and signaling, methylglyoxal (MG) detoxification upregulation gene expression for antioxidant enzymes, metal chelation xenobiotic detoxification. However, under extreme stresses, biosynthesis may get inhibited, causing an excess accumulation ROS that induces oxidative damage Hence, this gives rise idea exploring use exogenous mitigating various abiotic stresses. Extensive studies conducted borne positive results growth with integration GSH. same being observed terms crop yield index correlated intrinsic properties. Though, improvement contributed by limited subjected glutathione pool [GSH/GSSG; ratio reduced (GSH) oxidized (GSSG)] homeostasis. Therefore, recent focused sequenced application was performed order complement existing limitation.

Encapsulation in agriculture today is practically focused on agrochemicals such as pesticides, herbicides, fungicides, or fertilizers to enhance the protective nutritive aspects of entrapped active ingredients. However, one most promising and environmentally friendly technologies, biostimulants, hardly explored this field. biostimulants could indeed be an excellent means counteracting problems posed by their nature: they are easily biodegradable, them run off through soil, losing compounds, thus becoming inaccessible plants. In respect, encapsulation seems a practical profitable way increase stability durability under field conditions. This review paper aims provide researchers working plant with quick overview how get started encapsulation. Here we describe different techniques offer protocols suggestions for introduction polymer science improve properties future agricultural applications.

It has been established that wheat (Triticum aestivum L.) a higher Cd absorption capacity than other cereal crops causing an excess daily intake and huge threat for public health. Therefore, the reduction of accumulation in from soil is crucial food-security issue. A pot trial was performed on Cd-stressed seedlings to evaluate morphological physio-biochemical responses via foliage spray two different bio-stimulants, i.e., ascorbic acid (AsA) moringa leaf extract (MLE). Two cultivars (Fsd-08 Glxy-13) were exposed cadmium (CdCl2.5H2O) stress (0, 500, 1,000 μM), along with foliar AsA (0 50 mM) MLE 3%). The most observable growth documented plants are concentration (1,000 followed by lower level (500 μM). attributes, such as number leaves per plant, tillers biomass yield, shoot/root length, area, greatly depressed under stress, irrespective cultivar. Under increasing significant diminution observed maximum photochemical efficiency (Fv/Fm), quenching (qP), electron transport rate (ETR) accompanied reduced gas exchange attributes. However, Cd-induced phytotoxicity enhanced non-photochemical (NPQ) internal carbon dioxide (Ci), which confirmed their positive correlation contents shoot root tissues both cultivars. proline, AsA, glycine betaine (GB), tocopherol, total free amino (TFAA), soluble sugar (TSS) decreased while significantly osmolytes levels (especially 500 μM level). predominantly found compared shoots cultivars, declined after application AsA.

Abstract BACKGROUND Biostimulants are increasingly integrated into production systems with the goal of modifying physiological processes in plants to optimize productivity. Specifically, l ‐α‐amino acid‐based biostimulants enhance plant productivity through improved photosynthesis and increased assimilation essential nutrients such as nitrogen (N). This element is a major component fertilizers, which usually applied excess. Thus, inefficient use N fertilizers has generated serious environmental pollution issue. The potential address problems related fertilization. Therefore, objective this study analyze whether two based on acid (Terra Sorb® radicular Terramin® Pro) designed by Bioiberica, S.A.U company can compensate deficient fertilization test its effect lettuce plants. Growth, photosynthetic, accumulation, efficiency (NUE) parameters were analyzed leaves. RESULTS Results showed that regardless fertilization, both biostimulants, especially Pro, biomass production. Moreover, enhanced NO 3 − total accumulations well NUE parameters. CONCLUSION Terra Pro constitute useful tool for crops development N‐limiting areas, intensive agricultural areas without deficiency allowing reduction inputs impairing crop yields reducing impact. © 2022 Authors.

Water deficit stress exposure frequently constrains plant and agri-food production globally. Biostimulants (BSs) can be considered a new tool in mitigating water stress. This study aimed to understand how BSs influence perceived by savory plants (Satureja hortensis L.), an important herb used for nutritional herbal purposes the Middle East. Three BS treatments, including bio-fertilizers, humic acid foliar application of amino (AA), were implemented. Each treatment was applied using three irrigation regimes (low, moderate severe FC100, FC75 FC50, respectively). Foliar AA increased dry matter yield, essential oil (EO) content EO yield 22%, 31% 57%, respectively. The greatest yields resulted from (FC75) (FC50) treatments treated with AA. Primary constituents included carvacrol (39-43%), gamma-terpinene (27-37%), alpha-terpinene (4-7%) p-cymene (2-5%). enhanced carvacrol, gamma-terpinene, 6%, 19%, 46% 18%, Physiological characteristics increasing shortage Moreover, maximum activities superoxide dismutase (3.17 unit mg-1 min-1), peroxidase (2.60 min-1) catalase (3.08 obtained subjected We conclude that under conditions would improve quantity quality savory.

This study investigates the potential of a biostimulant derived from Selenicereus undatus peel waste and enriched in betalain degradation products (BDP), to influence Arabidopsis thaliana seedling development. Notably, lower BDP concentrations enhanced development, while higher dosages exhibited adverse effects. Assessment mitochondrial activity both seeds purified organelles showed that tested did not affect or integrity, highlighting its independence performance. Mechanistically, BDP-enriched modulated ROS-signaling, diminishing H2O2 by regulating enzymatic gene expression SOD, CAT, GPX, GR. Particularly, analyzing their different isoform via qRT-PCR, primary cellular compartment where detoxification occurred were identified. Furthermore, was able proline-accumulation, altering metabolism (PC5S, P5CR OAT) catabolism (PDH P5CDH) related genes. Finally, altered phytohormone levels, mainly affecting ABA/ABA-glu, tZea/tZea-rib, tZea/IAA. Concerning GAs, increase GA4 GA7 suggested an involvement GA13ox, hypothesis encouraged qRT-PCR analysis. In summary, this underscores BDP-based as sustainable promoters plant growth, influencing critical regulatory pathways during germination.

The growth-promoting and heat-mitigating effects of a commercially available protein-hydrolysate-based biostimulant, Kaishi, during the early vegetative stage was investigated by applying it as foliar spray on soil-grown maize plants or in nutrient solution hydroponically grown plants. At 10−3 dilution, biostimulant inhibited germination delayed growth progress, while at 10−6–10−12 dilutions, promoted shoot root growth. Heat stress caused biomass reduction, decreased leaf pigment content chlorophyll a/chlorophyll b (chl a/b) ratio, starch depletion, increased lipid peroxidation. Kaishi priming resulted substantial mitigation negative effects, maintaining growth, stabilizing chl a/b restoring content, lowering malondialdehyde (MDA) level, significantly increasing free proline content. expression profiles set genes coding for heat shock proteins (HSPs), dehydrins (DHNs), proteases were analysed using qRT-PCR after exposure. biostimulant-treated had higher transcript levels certain HSPs, DHNs, protease-coding genes, which remained stable applied stress. results demonstrate that very low concentrations exerted stress-mitigating could be linked to organ-specific changes gene stress-inducible proteins.
