Copper is essential but toxic in excess for aerobic organisms. Yeast transcription factor ACE1 functions as a sensor for copper and an inducer for the transcription of CUP1. In addition, ACE1 can activate the transcription of superoxide dismutase gene (sod1) in response to copper. In this study, we introduced the yeast ACE1 into Arabidopsis and analyzed its function in plant. Under high copper ...

in this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. residual sludge from an electroplating plant located in qingdao was used for acid-leaching, and more than 95% of copper, nickel, zinc, chromium and iron were extracted from the sludge. after acid-leachi...

Plant growth and activity of peroxidases (POX) and phenylalanine ammonia-lyase (PAL) were investigated in seedlings of yellow lupine (Lupinus luteus L.) and soybean (Glycine max L.) treated with copper (25 mg/l) and an inhibitor of ethylene biosynthesis (CoCl 2 ). Both lupine and soybean plants stressed with an excess of copper exhibited a decrease in root length and fresh weight. In lupine pla...

The Moldavian dragonhead (Dracocephalum moldavica L., Lamiaceae) is an annual medicinal plant with beneficial nutritional sources that plays important roles in human and animal feed. Nanoparticles and cold atmospheric plasma increase biochemical compounds in plants. In this study, the effects of copper nanoparticles and cold atmospheric plasma on biochemical indices of the medicinal plant Draco...

To assess the tolerance and phytoaccumulation ability of the duckweed Lemna gibba L. to copper (Cu) and nickel (Ni), the aquatic plants were exposed to different concentrations of Cu and Ni (0.1 – 2.0 mg/L) in quarter Coïc and Lesaint solution at pH = 6.0 (± 0.1) and under a daily regime of 12 h light. Copper and nickel were tolerated by L. gibba at concentrations ≤ 0.3 mg/L and ≤ 0.5 mg/L, res...

MicroRNAs (miRNAs) are a class of non-coding, small RNAs recognized as important regulators of gene expression. Although plant miRNAs have been extensively studied in model systems, less is known in other plants with limited genome sequence data, including Paeonia ostii. In this work, we used high-throughput sequencing to identify conserved and nonconserved miRNAs and other short RNAs in Paeoni...

This paper introduces an integrated design for realtime plant modeling at a copper mine, using Support Vector Machines (SVM), Neural Networks, and new technologies such as Machine-to-Machine (M2M) and Cloud Computing with an Android client. This solution was designed for a plant inside a copper mine which cannot tolerate interruption and for which their in situ modeling, in real time, is an ess...

In order to measure serum copper concentration, 163 adult males working at different units of copper plant from a total population of 671, were selected by simple random sampling. Eighty three subjects working at melting foundry, 49 in extrugen- rolling and 31 at administrative service untils. Eighty four adult male natives of Kerman and it's suburbs were randomly choosen as control group, seru...
