Soil salinity is a serious global problem that threatens high percentage of the soils. Salinity stress can create ionic, oxidative, and osmotic stress, along with hormonal imbalances, in stressful plants. This kind was investigated on agricultural productivity at different levels, starting vitro (plant tissue culture), through hydroponics, pots, field conditions. Several approaches were studied for managing including using traditional materials (e.g., gypsum, sulfur), organic amendments compost, biochar, chitosan), applied manufactured or engineered nanomaterials (NMs). Application ameliorating has gained great attention due to their efficiency, eco-friendliness, non-toxicity, especially biological nanomaterials. The application NMs did not only support growing plants under but also increased yield crops, provided an economically feasible nutrient management approach, environmentally robust sustainable crop productivity. Nano-management may involve applying nano-amendments, nanomaterials, nano-enabled nutrients, nano-organic amendments, derived smart nanostructures, nano-tolerant plant cultivars. Producing cultivars are tolerant be achieved conventional breeding plantomics technologies. In addition large-scale use there urgent need address treat nanotoxicity. study aims contribute this area research by exploring nano-management current practices raises many questions regarding expected interaction between toxic effects such includes whether acts positively negatively cultivated soil activity, what regulatory ecotoxicity tests protocols should used research.

Melatonin: A potential abiotic stress regulator

Plant Stress, Journal Year: 2023, Volume and Issue: 10, P. 100293 - 100293

Published: Nov. 15, 2023

Abiotic stress adversely affects the metabolism and growth of plants, hampering their yield productivity. Melatonin is a ubiquitous, multifunctional, regulatory, non-toxic potential bio stimulator possessing pleiotropic effects in plant kingdom. It master regulator which plays critical role under abiotic conditions. Studies indicate increases endogenous levels melatonin plants. On other hand, exogenous has also been reported to mitigate plants by modulating proteins gene expressions. Melatonin-mediated reactive oxygen species scavenging defense system activation are primary mechanisms employed make alleviating stress. This review summarizes recent research concerning phytomelatonin biosynthesis, its detection techniques, We have focused on regulatory drought, heat, cold, heavy metal, acid rain, toxic chemical, light, herbicide Additionally, crosstalk with phytohormones considered.

High salinity reduces agriculture production and quality, negatively affecting the global economy. Zinc oxide nanoparticles (ZnO-NPs) enhance plant metabolism abiotic stress tolerance. This study investigated effects of 2 g/L foliar NPs on Zea mays L. plants to ameliorate 150 mM NaCl-induced salt stress. After precipitation, ZnO-NPs were examined by UV–visible spectroscopy, transmission electron microscopy, scanning energy dispersive X-ray, particle size distribution. height, stem diameter (width), area leaves, chlorophyll levels, hydrolyzable sugars, free amino acids, protein, proline, hydrogen peroxide, malondialdehyde. Gas chromatographic analysis quantified long-chain fatty following harvest, stalks, cobs, seeds, seeds per row weighed.

To address rising global food demand, the development of sustainable technologies to increase productivity is urgently needed. This study revealed that foliar application zinc oxide nanoparticles (ZnO NPs; 30 80 nm, 0.67 mg/d per plant, 6 d) rice leaves under heatwave (HW) stress increased grain yield and nutritional quality. Compared with HW control, HWs+ZnO group presented increases in yield, protein content, amino acid content 22.1%, 11.8%, 77.5%, respectively. Nanoscale ZnO aggregated on leaf surface interacted molecules. at ambient temperature, treatment dissolution NPs by 25.9% facilitated their translocation mesophyll cells. The Zn existed as both ionic particulate ZnO. conditions nutrient levels (Zn, Mn, Cu, Fe, Mg) 15.8 416.9%, chlorophyll 22.2 24.8%, Rubisco enzyme activity 21.2%, antioxidant 26.7 31.2%.
