Melatonin is a pleiotropic molecule that can influence various aspects of plant performance. Recent studies have exhibited it mediates defensive responses, probably through managing redox homeostasis. We tried to track the regulatory effects melatonin on antioxidant machinery Linum album cell culture. To this, different concentrations were applied, and oxidative status cells was investigated by measuring levels molecules agents. The results showed H2O2 content did not change at low levels, while increased high concentrations. It be correlated with dosages capacity remove excessive amounts H2O2, exhibit toxicity effects. In contrast, NO enhancement occurred 50 μM melatonin, proposing its role in triggering melatonin-induced responses. MDA stated led stress melatonin-treated melatonin.

Abstract In recent decades, the demand for vegetables has increased significantly due to blooming global population. Climate change affected vegetable production by increasing frequencies and severity of abiotic biotic stresses. Among stresses, drought salinity are major issues that possess severe threats on production. Many (e.g., carrot, tomato, okra, pea, eggplant, lettuce, potato) usually sensitive salt stress. The defence mechanisms plants against stress have been extensively studied in model plant species field crops. Better understanding susceptibility stresses will help towards development more tolerant genotypes as a long-term strategy these However, intensity challenges also warrants immediate approaches mitigate enhance short term. Therefore, this review enlightens updated knowledge responses (physiological molecular) potentially effective strategies Moreover, we summarized different technologies such seed priming, genetic transformation, biostimulants, nanotechnology, cultural practices adopted under We propose conventional breeding, engineering, crop management should be combined generate resistance cultivars adopt smart cultivation sustainable changing climate.

Abstract Seed germination (SG) is the first stage in a plant's life and has an immense importance sustaining crop production. Abiotic stresses reduce SG by increasing deterioration of seed quality, reducing potential, vigor. Thus, to achieve sustainable level yield, it important improve under abiotic stress conditions. Melatonin (MEL) biomolecule that interplays developmental processes regulates many adaptive responses plants, especially stresses. this review specifically summarizes discusses mechanistic basis MEL‐mediated MEL regulating some stress‐specific common responses. For instance, induced specific include regulation ionic homeostasis, hydrolysis storage proteins salinity stress, C‐repeat binding factors signaling cold starch metabolism high temperature heavy metal activation aquaporins accumulation osmolytes drought stress. On other hand, mediated gibberellins biosynthesis abscisic acid catabolism, redox Ca 2+ are amongst Nonetheless such as endogenous contents, plant species, growth conditions also influence above‐mentioned In conclusion, interacting with different physiological mechanisms.

Melatonin acts as a multifunctional molecule that takes part in various physiological processes, especially the protection against abiotic stresses, such salinity, drought, heat, cold, heavy metals, etc. These stresses typically elicit reactive oxygen species (ROS) accumulation. Excessive ROS induce oxidative stress and decrease crop growth productivity. Significant advances melatonin initiate complex antioxidant system modulates homeostasis plants. Numerous evidences further reveal often cooperates with other signaling molecules, ROS, nitric oxide (NO), hydrogen sulfide (H2S). The interaction among melatonin, NO, H2S, orchestrates responses to via networks, thus conferring plant tolerance. In this review, we summarize roles of establishing redox through current progress interactions higher stresses. We highlight vital role respiratory burst oxidase homologs (RBOHs) during these processes. complicated integration occurs between plants is also discussed.

The excessive accumulation of copper (Cu2+) has become a threat to worldwide crop production. Recently, it was revealed that melatonin (MT) could play crucial role against heavy metal (HM) stresses in plants. However, the underlying mechanism MT function acted upon by Cu2+ stress (CS) not been substantiated tomatoes. In present work, we produced MT-rich tomato plants foliar usage MT, and MT-deficient employing virus-induced gene silencing methodology exogenous application synthesis inhibitor para-chlorophenylalanine (pCPA). obtained results indicate meaningfully alleviated dwarf phenotype impeded reduction plant growth caused excess Cu2+. Furthermore, effectively restricted generation reactive oxygen species (ROS) habilitated cellular integrity triggering antioxidant enzyme activities, especially via CAT APX, but SOD POD. addition, increased nonenzymatic activity, including FRAP GSH/GSSG ASA/DHA ratios. improved expression several defense genes (CAT, GR MDHAR) biosynthesis-related (TDC, SNAT COMT). Taken together, our preliminarily reveal alleviates toxicity ROS scavenging, enhancing capacity when subjected These build solid foundation for developing new insights solve problems related CS.
