With increasing plastic production and consumption, large amounts of polystyrene nanoplastics are accumulated in soil due to improper disposal causing pollution deleterious effects environment. However, little information is available about how alleviate the adverse impacts on crops. In this study, involvement melatonin modulating nanoplastic uptake, translocation, toxicity wheat plant was investigated. The results demonstrated that exogenous application reduced uptake by roots their translocation shoots via regulating expression genes associated with aquaporin, including upregulation TIP2-9, PIP2, PIP3, PIP1.2 leaves PIP1-5, roots. Melatonin activated ROS scavenging system maintain a better redox homeostasis ameliorated negative carbohydrate metabolism, hence growth enhanced tolerance toxicity. This process closely related induced accumulation leave. These suggest could wheat, might be used as promising management strategy sustain crop nanoplastic-polluted soils.

Melatonin is an indolic compound derived from tryptophan and has important role in the general processes of plants including germination, photosynthesis, circadian rhythms, flowering, senescence, alleviating stress. Integrating melatonin application to agronomical practices reportedly provides numerous benefits. More particularly seed priming with been shown improve germination as well resilience under adverse conditions. This review discusses detail studies showing elevated drought, salinity, heat, heavy metal stress resistance a result priming. Differences transcript protein levels have observed plants/seedlings germinated via primed seeds, providing foundation for further studies. Many pieces research also seeds possess greater content osmoprotectants, upregulation energy-producing pathways, increase content, which may lead enhancing abiotic response plants. The primary function attributed reactive oxygen species scavenging, consequently leads plant against multiple stresses. Here, we highlight all potential mechanisms involved meditated induction tolerance. We reports emphasizing played by conditions crop species, modification at genome, ribonucleic acid, level involved, underlying mechanisms. Information provided here will be helpful better understand its efficient exploration cropping system.

Environmental variations caused by global climate change significantly affect plant yield and productivity. Because water scarcity is one of the most significant risks to agriculture's future, improving performance plants cope with stress critical. Our research scrutinized impact melatonin application on photosynthetic machinery, physiology, root system, osmoprotectant accumulation, oxidative in tomato during drought. The results showed that melatonin-treated had remarkably higher levels, gas exchange activities, system morphological parameters (average diameter, activity, forks, projected area, crossings, volume, surface length, tips, numbers), (proline, trehalose, fructose, sucrose, GB) transcript levels genes SlPsb28, SlPetF, SlPsbP, SlPsbQ, SlPetE, SlPsbW. In addition, effectively maintained plants' physiology. Moreover, treatment soluble protein content antioxidant capacity Melatonin also resulted membrane stability, evidenced less electrolyte leakage lower H2O2, MDA, O2- drought-stress environment. Additionally, enhanced defense enzymes antioxidant-stress-resistance-related gene (SlCAT1, SlAPX, SlGR, SlDHAR, SlPOD, SOD) plants. These outcomes imply impacts drought resistance could be ascribed mitigation function inhibition, enhancement status, alleviation study findings reveal new incredible aspects response provide a list candidate targets for increasing tolerance
