“…This ROS is also involved in the polymerization of proteins that make up the cell wall and in the stimulus for the production of antioxidative enzymes (Łukasik et al, 2012). Due to its redox nature, Cu increases the generation of H2O2 which, in addition to the aforementioned functions, is a molecule that can modulate plant growth and development (Nazir et al, 2019). This molecule also activates the tolerance of plants to stress conditions (Zhou et al, 2018), improves photosynthetic activity (Khan et al, 2016;Noctor et al, 2018), and increases stomatal conductance (Deng et al, 2012;Y.…”

Conducting a field study to investigate the effects of foliar and soil fertilization with copper on the nutritional and physiological parameters and grain yield of common bean. The experimental design was a randomized block, in a 2 x 5 factorial scheme. The first factor was the site of application of copper fertilization. The second factor was copper doses: 0, 1, 2, 3, and 4 kg ha-1 (6 replicates). The following were evaluated: leaf nitrogen and copper contents, relative chlorophyll index (RCI), gas exchange, photochemical efficiency of photosystem II, and grain yield. The data were subjected to analysis of variance and F test (p-value < 0.05), using the Scott & Knott for qualitative data and polynomial regression for quantitative data. Leaf Cu content was higher with soil application (4% and 28%), both at 24 and 45 DAE, respectively. Net photosynthesis reached a maximum index of 18.77 µmol m-2 s-1 with foliar Cu fertilization at the dose of 4 kg ha-1. The application of 2.0 kg ha-1 Cu was the one that led to the highest grain yields; however, soil application stood out with a yield about 12% higher of the foliar. Soil fertilization proved to be more efficient in terms of Cu absorption and RCI rates, improving grain yield (12%) in relation to foliar, especially at the dose of 2 kg ha-1. The dose of 2 kg Cu ha-1 provided the best differential profit, reaching US$ 581.96 ha-1 and US$ 503.01 ha-1 for soil and foliar application, respectively.

“…Copper stress can stimulate a variety of defense mechanisms in plants such as antioxidant systems and antioxidants to control copper homeostasis (Yadav et al 2018, Nazir,Hussain and Fariduddin 2019. Some metabolites (such as amino acids and avonoids) have antioxidant effects in plants (Kovacik et al 2010, Agati et al 2020.…”

Background and aim Phragmites australis is a landscape plant with phytoremediation functions that is widely planted worldwide. However, little is known about the metabolomic background of the resistance mechanisms of Phragmites to heavy metals during its growth and development. Methods Here, we performed copper stress studies on Phragmites and monitored physiological indicators such as malondialdehyde (MDA) and electrolyte leakage (EL). In addition, FTIR was used to study chemical composition changes in the roots, stems and leaves of Phragmites seedlings under excessive copper stress. Furthermore, LC-MS technology combined with metabolomics data processing software was used to analyze the metabolic profile of samples.Result Copper contributed to the accumulation of MDA and EL. And the results of FTIR showed that the antioxidant effects of flavonoids and amino acids can be used by Phragmites leaf tissue to improve the tolerance of copper under 5 mg/L concentration. Further, the results of metabolomics reflected that Phragmites can improve its resistance to copper by increasing the accumulation of arginine and ayarin in the body. The former is accumulated through two pathways: the citrulline decomposition and conversion pathway and the circular pathway composed of ornithine, citrulline, L-Argininosuccinate and arginine. The latter is synthesized through the quercetin methylation pathway.Conclusion This study provides insights into the resistance mechanism and repair performance of Phragmites and other plant accumulators in response to copper stress.

“…In several studies, elevated acquisition of Cu was culminated into chlorosis, leaf epinasty, decreased branching, thickening, and dark coloration (Nair and Chung, 2015;Ali et al, 2016) and also to the development of necrotic patches in leaf tips and margins (Llagostera et al, 2016). Altered surface root morphology, rolling of the leaf blade and reduced leaf area were also reported in plants under elevated Cu-exposure (Sánchez-Pardo et al, 2014;Nazir et al, 2019). Phytotoxic concentrations of Cu also impede the leaf proliferation, cell elasticity, and cell division and reduced the number and abundance of intercellular spaces and densely developed dark colored areas of xylem vessels (Ambrosini et al, 2018;Shiyab, 2018).…”

Mechanisms and Role of Nitric Oxide in Phytotoxicity-Mitigation of Copper

et al. 2020

View full text Add to dashboard Cite

Phytotoxicity of metals significantly contributes to the major loss in agricultural productivity. Among all the metals, copper (Cu) is one of essential metals, where it exhibits toxicity only at its supra-optimal level. Elevated Cu levels affect plants developmental processes from initiation of seed germination to the senescence, photosynthetic functions, growth and productivity. The use of plant growth regulators/phytohormones and other signaling molecules is one of major approaches for reversing Cu-toxicity in plants. Nitric oxide (NO) is a versatile and bioactive gaseous signaling molecule, involved in major physiological and molecular processes in plants. NO modulates responses of plants grown under optimal conditions or to multiple stress factors including elevated Cu levels. The available literature in this context is centered mainly on the role of NO in combating Cu stress with partial discussion on underlying mechanisms. Considering the recent reports, this paper: (a) overviews Cu uptake and transport; (b) highlights the major aspects of Cu-toxicity on germination, photosynthesis, growth, phenotypic changes and nutrient-use-efficiency; (c) updates on NO as a major signaling molecule; and (d) critically appraises the Cu-significance and mechanisms underlying NO-mediated alleviation of Cu-phytotoxicity. The outcome of the discussion may provide important clues for future research on NO-mediated mitigation of Cu-phytotoxicity.
