Copper (Cu) is essential for plant life because of its key role in photosynthetic electron transport, respiration, and perception of the plant hormone ethylene. The most abundant Cu protein in plants is plastocyanin, an electron carrier in the chloroplast thylakoid lumen that is essential for ...
Copper (Cu) is one of the micronutrients needed by living organisms. In plants, Cu plays key roles in chlorophyll formation, photosynthesis, respiratory electron transport chains, oxidative stress protection as well as protein, carbohydrate, and cell wall metabolism. Therefore, deficiency of Cu can ...
Unlike other heavy metals, such as cadmium, lead, and mercury, copper is not readily bioaccumulated and thus its toxicity to man and other mammals is relatively low. On the contrary, plants in general are very sensitive to Cu toxicity, displaying metabolic disturbances and growth inhibition at ...
Copper in soils, plants, and ruminant animal nutrition with special reference to sub-Saharan Africa. Journal of Plant Nutrition, New York, v. 16, n. 11, p. 2149-2212, 1993.Haque I, Aduayi EA, Siband S (1992) Copper in soils, plants and ruminants animal nutrition with special ...
Poly(gamma-glutamylcysteinyl)glycine: its role in cadmium resistance in plant cells. Angiosperms can be selected for the ability to grow in the presence of normally toxic concentrations of certain trace metal ions. Addition of Cd and Cu to ... PJ Jackson,CJ Unkefer,JA Doolen,... - 《Procee...
We also identified genes that were not previously known to play a role in iron metabolism. Deletion of the gene CWH36 resulted in a severe growth ... Sandra R. Davis-Kaplan,MV Ward,SL Shiflett,... - 《Journal of Biological Chemistry》 被引量: 106发表: 2004年 Novel insights into iron...
Copper (Cu) contamination of soils may alter the functioning and sustainability of vineyard ecosystems. Cultivating Cu-extracting plants in vineyard inter-rows, or phytoextraction, is one possible way currently under consideration in agroecology to reduce Cu contamination of vineyard topsoils. This option...
Effect of copper-tolerant rhizosphere bacteria on mobility of copper in soil and copper accumulation by Elsholtzia splendens The role of rhizosphere bacteria in facilitating the solubility of copper (Cu) in contaminated soil and Cu accumulation in plant were studied. The bacteria... XC Ying,YP ...
Although copper is an essential micronutrient that plays an important role in organisms, high copper concentrations may trigger toxicity to animals and plants. Here, we investigated whether Plinia peruviana hydroalcoholic extract prevents copper-induced cytotoxicity in Allium cepa root cells. Five different...
metal and a micronutrient with two distinct functions - to serve as a plant nutrient by being an activator or by being a part of certain enzymes like tyrosinase, lactase, ascorbic acid oxidase, cytochrome oxidase, etc., and secondly to play a role in many electron transfer processes. adsorbed...
