This review summarizes recent advances in our understanding of mechanisms of Cu function in plants and Cu transporters, orchestrating the adequate Cu uptake into roots and internal transport to ensure plant vigor. We also highlight new emerging avenues for the investigation into Cu mobilization ...
In the environments,excess copper will impair the plant cells,inactivate enzymes and destroy protein structure.There is a complex metal trafficking network to appropriately regulate copper homeostasis in plants.This review gave a brief overview of copper toxicity and recent progresses about copper transpor...
Abnormal accumulation of Co occurs under similar circumstances in the Copperbelt of Central Africa as well as sporadically in Ni hyperaccumulator plants on ultramafic soils; however, Co-tolerant plants behave physiologically as Indicators Baker. Practical application of Cu–Co accumulator plants in ...
The high toxicity of Cu to plants has led to the evolution of several strategies of defense. Among the most important ones is the production of Cu-complexing compounds. Although the nature, structure, and function of these compounds is still controversial, they can be divided into two main gro...
Plants were exposed in hydroponics for 21 days to different Cu concentrations (10, 15, 20, and 30 mg/L). Significant declines in chlorophyll, carotenoids, and soluble proteins, as a function of Cu proportion were observed. Lipid peroxidation was also evident, which implied reactive oxygen ...
This work is the first report on the physiological function of copper transport in Arabidopsis thaliana. We have studied the expression pattern of COPT1 in transgenic plants expressing a reporter gene under the control of the COPT1 promoter. The reporter gene is highly expressed in embryos, ...
Barley grass (both H. glaucum Steud. and H. leporinum Link) was more tolerant of low Mn and Cu status than wheat, especially in terms of growth and photosynthetic response to Mn deficiency. Wheat plants made little growth once Mn supply was reduced to 10% of control level whereas barley ...
Improvements introduced in plants for the continuous production of copper cyanamide which has a combined antiparasitic and fertilizer action, whose improvements include means for obtaining a suspension of calcium cyanamide (or cyanamide solution) and calcium hydroxide in water, means for reacting the ...

In plants, addition of a methyl group to the cytosine residue in the three contexts is mediated by a group of DNA methyltransferases such as MET1 (METHYLTRANSFERASE 1) mainly for CG, CMT3 (CHROMOMETHYLASES) for CHG, and DRM2 (DOMAINS REARRANGED METHYLTRANSFERASE 2) for CHH [39, 40]. ...
