Toxicity of copper oxide nanoparticles on spring barley (Hordeum sativum distichum)

Interaction of Copper-Based Nanoparticles to Soil, Terrestrial, and Aquatic Systems: Critical Review of the State of the Science and Future Perspectives

“…Previous studies showed an increased number of plastoglobules due to biotic, abiotic and CuO-NPs induced stress in Landoltia punctate (Lalau et al 2015). The excess concentration of CuO-NPs severely affected starch content, stomatal aperture, epidermis, endodermis, cell wall, mitochondria, nuclei and vascular bundles of H. sativum (Rajput et al 2018a).…”

“…Once NPs infiltrate the plant system, they may traverse to different organs (leaves, stem, and fruits) or may get compartmentalized at different locations viz. vacuoles, walls, stellar system, cytoplasmic matrix, lipid envelopes, and nucleus (Ahmed et al 2018b;Rajput et al 2017bRajput et al , 2018aRastogi et al 2017). The translocation efficiency varies greatly in different plant species, for instance, alfalfa translocates 3-5% of Cu from root to shoot on exposure to 0-20 mg L -1 Cu-NPs, whereas only 0.5-0.6% translocation was observed in lettuce (Hong et al 2016).…”

“…It has further been reported that the CuO-NPs had a detrimental impact on the structure and function of the photosynthetic apparatus especially on photosynthetic pigments, chlorophyll, and grana(Tighe-Neira et al 2018). Spring barley grown in hydroponic system showed accumulation of CuO-NPs in leaf cells and disorganized chloroplast structure and thylakoid in the mesophyll cells(Rajput et al 2018a).…”

Copper and copper nanoparticles toxicity and their impact on basic functions in the body

“…Toxicity of copper oxide nanoparticles is also manifested on plants (165). In a complex experiment, Rajput and co-workers described the impact of copper oxide nanoparticles on spring barley (Hordeum sativum) as a representative staple food crop (166). The barley grown in the presence of copper nanoparticles had a reduced size, changes in morphology and depressed yield of photosynthesis.…”

Biocontrol of phytobacteria with bacteriophage cocktails

“…Contamination of soil with copper damaged the photosynthetic pigments and interfered with the growth and gas exchange of three vegetables ( Brassica alboglabra , Brassica chinensis and Chrysanthemum coronarium ) . Copper oxide nanoparticles were also found to interfere with the rate of germination, and growth of roots and shoots of spring barley ( Hordeum sativum distichum) . Resistance to copper‐based bactericides is also a challenge in the control of phytopathogens .…”
