Few relevant research attempts have been made to determine heavy metal resistance mechanisms of rhizomatous perennial plants. Thus, it is pertinent to investigate the physiological and biochemical changes in Phragmites australis under metal‐stressed conditions to facilitate the development of strategies to enhance copper (Cu) tolerance. We measured parameters related to plant growth and development, metal translocation and physiological responses of P. australis subjected to Cu stress. In addition, the differentially expressed proteins (DEP) were evaluated using the isobaric tag for relative and absolute quantification (iTRAQ) system. A large amount of copper accumulates in the roots of P.australis, but the growth parameters were not sensitive to Cu. However, the high concentration of Cu reduced the content of chlorophyll a and chlorophyll b, and the expression of important photosynthesis proteins PsbD, PsbO and PsaA were all down‐regulated, so photosynthesis was inhibited. In contrast, the content of ascorbic acid and proline both increased with the increase of copper stress. P.australis fixed a large amount of Cu in its roots, limiting the migration of Cu to other parts of the plant. Moreover, Cu stress can affect photosynthesis by inhibiting the activity of PSI, PSII and LHCII. In addition, P.australis synthesizes ascorbic acid through the D‐mannose/L‐galactose pathway, and synthesizes proline through the ornithine pathway. Ascorbic acid and proline can increase Cu tolerance and protect photosynthesis. These results provide a theoretical basis for understanding the tolerance and repair mechanisms of plants in response to heavy metal pollution.

“…This mineral overloaded water is then absorbed by roots and transferred into aerial parts of plants causing toxicity. The effect of heavy metal on various physiological, biochemical, cytological and molecular levels are already well elaborated (Malec et al 2008;Maleva et al 2009;Yusuf et al 2012;Siddiqui 2013;Š iukšta et al 2019). Human and animal ingestion of metals occur primarily through plants when used as food or fodder.…”

This study pertains to the effects of heavy metal salts viz., copper (Cu), manganese (Mn), lead (Pb) and zinc (Zn) on the chickpea accession ICC-4812. The salts were given as treatments to the chickpea seeds at various ascending levels of doses till proving toxic. The treatment of 24 h soaked and swollen seeds were then extended to 7 days duration from the date of treatment. Atomic absorption spectrophotometric analysis of bioassay tissue Cicer, showed maximum uptake of 9.41 mg/g and minimum of 1.65 mg/g tissue dry weight for Pb and Zn respectively. The study reveals that enhanced antioxidant responses are associated with substantial proline accumulation indicating induced stress. Ferric reducing antioxidant power assay measuring antioxidant activity was highest in the chickpea seedling treated with Zn, whereas, free radical scavenging activity was highest in the treatments with Mn. The total phenolic and flavonoid contents ranged between 0.24-0.97 and 0.27-1.00 mg/g of dry matter content respectively. Higher Pb and Zn doses seem to elicit higher proline levels therefore, suggesting an extreme condition of induced abiotic stress. Dose dependent protein oxidation coupled with DNA degradation was observed in all treatments, depicting genotoxicity. Unweighted pair-group method arithmetic average analysis presented similarity coefficients between the treatments.

“…Therefore, a combination of in vitro experiments involving microorganisms and plants have been used to provide more practical view of the genotoxicity of the mutagens ( Gupta et al., 2020 ; Khan et al., 2019 ). Genotoxicity of wastewater irrigated soil have been evaluated by many researchers using plants such as Allium cepa ( Gallego and Olivero-Verbel, 2021 ) Vicia faba ( Gupta et al., 2020 ) Tradescantia ( Šiukšta et al., 2019 ) and bacterial assay likewise Ames test and SOS DNA repair ( Ansari and Malik, 2009 ). The aim of current study was genotoxicity assessment of soil irrigated with the wastewater employing Ames Salmonella /mammalian microsome test, plasmid nicking test, DNA repair defective E. coli K-12 mutants, Allium cepa root chromosomal aberration test and oxidative damage in the roots of Vigna radiata plant.…”
