Copper mediated inhibition on protein synthesis in rice shoots

摘要: Abstract Recently several claims of copper (Cu) contamination in the lower reaches Sado River Alcacer do Sal region Portugal (a major rice producing area) have been reported. In an attempt to study effect excess Cu on protein contents without anthropogenic interventions (amendments with fertilizers and sludges, application pesticides, etc.), (Oryza sativa L.) plants were grown for one month nutrient solutions containing concentrations ranging from 0.002 6.25 mg/L. order understand mechanism responsible observed decline content increasing levels, membrane permeability as well acid RNAse protease activities investigated. It was found that activity increased concentration. An increase also observed, but only at two highest treatments. The effects levels are discussed bas...
