Abstract The primary factors that restrict agricultural productivity and jeopardize human food safety are heavy metals (HMs), including arsenic, cadmium, lead, aluminum, which adversely impact crop yields quality. Plants, in their adaptability, proactively engage a multitude of intricate processes to counteract the impacts HM toxicity. These orchestrate profound transformations at biomolecular levels, showing plant’s ability adapt thrive adversity. In past few decades, stress tolerance crops has been successfully addressed through combination traditional breeding techniques, cutting-edge genetic engineering methods, strategic implementation marker-dependent approaches. Given remarkable progress achieved this domain, it become imperative adopt integrated methods mitigate potential risks arising from environmental contamination on yields, is crucial as we endeavor forge ahead with establishment enduring systems. manner, nanotechnology emerged viable field sciences. applications extensive, encompassing regulation stressors like toxic metals, improving efficiency nutrient consumption alleviating climate change effects. Integrating nanomaterials agrochemicals mitigated drawbacks associated agrochemicals, challenges organic solvent pollution, susceptibility photolysis, restricted bioavailability. Numerous studies clearly show immense nanofertilizers tackling acute crisis toxicity production. This review seeks delve into using NPs effectively enhance resilience, thereby fostering an environmentally friendly economically approach toward sustainable advancement foreseeable future.

The beneficial role of glycine betaine (GB) in the adaptation plants to abiotic stresses is well known; therefore, study physiological and molecular responses induced by exogenous GB under NaCl stress can provide a suitable reference for application this compound enhance salinity. present was conducted vitro conditions evaluate effect (25 50 mM) on growth, physiological, traits Stevia rebaudiana during toxicity (50 mM). results showed that applying treatment increased Na accumulation, oxidative stress, disrupted N metabolism K/Na homeostasis, which, as result, decreased stevia plant's growth biomass. However, improved NaCl-stressed improving modulating polyamines. By increasing activity antioxidant enzymes, diminished protected plasma membrane, restored photosynthetic pigments toxicity. reducing accumulation K maintained balance reduced effects caused high concentration leaves. leaf rebaudioside A expression genes (KAH, UGT74G1, UGT76G1, UGT85C2) involved sugar compounds plants. Our broad understanding GB-induced plants, which help increase our knowledge defense mechanisms stresses.

Nitric oxide in plants: an insight on redox activity and responses toward abiotic stress signaling

Plant Signaling & Behavior, Год журнала: 2024, Номер 19(1)

Опубликована: Янв. 8, 2024

Plants, as sessile organisms, are subjected to diverse abiotic stresses, including salinity, desiccation, metal toxicity, thermal fluctuations, and hypoxia at different phases of plant growth. Plants can activate messenger molecules initiate a signaling cascade response toward environmental stresses that results in either cell death or acclimation. Nitric oxide (NO) is small gaseous redox-active molecule exhibits plethora physiological functions growth, development, flowering, senescence, stomata closure responses stresses. It also facilitate alteration protein function reprogram the gene profiling by direct indirect interaction with target molecules. The bioactivity NO be manifested through redox-based modifications S-nitrosylation, nitration, nitrosylation plants. Although there has been considerable progress role regulating stress signaling, still mechanisms regarding tolerance plants remain unclear. This review summarizes recent advances understanding emerging knowledge against manuscript highlighted importance an modulator developed rational design for crop cultivation under environment.

There is little study on melatonin’s ability to prevent salt damage in eggplants, despite the fact that it a strong antioxidant plants has been found help mitigate variety of adverse challenges. In this study, we used “Anhui Eggplant No.8” as test material and simulated stress by irrigating roots with 150 mmol·L NaCl solution. Subsequently, treated eggplants different concentrations exogenous melatonin (0, 50, 100, 150, 200, 250 μmol·L) assessed plant traits an array physiological biochemical indices following application observe impact stress. Our results indicate at concentration 200 μmol·L can significantly alleviate inhibition eggplant photosynthesis under increasing content chlorophyll leaves activity enzymes. This leads notable increase levels non-enzyme antioxidants osmotic regulatory substances. As result, capacity enhanced, degree membrane lipid peroxidation reduced, growth seedlings effectively promoted, thereby strengthening tolerance seedlings.

Melatonin (MT) participates in plants' responses response to cadmium (Cd) tolerance, although its work model remains elusive. Here, the function of MT adjusting Cd accumulation Gossypium hirsutum (CCRI12) was investigated. In this research we observed that exogenous 50 μM significantly reduced under 100 μМ stress for 7 days treatment cotton seedlings. markedly induced ROS (H2O2, O2-) and elevated expression transporters uptake translocation. After application MDA high induction antioxidant defense system; genes encoding superoxide dismutase (GhSOD), catalase (GhCAT), peroxidase (GhPOD), ascorbate (GhAPX), glutathione S-transferase (GhGST) were upregulated accompanied by their level content. Furthermore, down-regulated include Natural Resistance-Associated Macrophage Protein 1 (GhNRAMP3), Zinc/Iron-regulated transporter-like protein (GhZIP1/4/6), Heavy Metal ATPase gene (GhHMA2), ATP-binding Cassette sub family C (GhABCC3/2). Exogenous raised hemicelluloses, cellulose pectin content levels, xyloglucan endotransglucosylase/hydrolase (GhXTH28/6/9/B), synthase like (GhCSLG1/2) COBRA-like (GhCOBL4), acetylesterases (GhPAE8/7), methylesterases (GhPME31) which turn increased cell wall's binding capacity Cd.
