主 题:copper Drosophila melanogaster esterase isozymes larval development protein
摘 要:Copper is an important ingredient in fungicides,which are used for many economic ***,there is concern about the side-effects of copper-based fungicides due to their potential to affect beneficial *** purpose of the present paper was to investigate the effects of copper on the development of the fruit fly,Drosophila *** was found that higher doses of copper significantly prolonged the developmental time of the fruit flies,especially during the larval *** 320 mg L-1 copper-contaminated food was used,most of the larvae died when they were small and before the pupal *** protein contents and esterase isozymes extracted from the larvae changed according to the doses of *** small-molecular-weight protein bands gradually became weaker or were lost as the copper levels ***,low doses of copper stimulated a stronger expression of a few *** results indicate that low doses of copper generally have no lethal effects on *** because a specific group of genes,which encode specific proteins,are probably activated in order to withstand the onslaught of stressful *** high doses of copper in food(e.g.320 mg L-1),fly development and viability are significantly affected.
