ฉันเป็นคนไม่ได้เรียนหนังสือIndiscriminate release of metal oxide nanoparticles (NPs) into the environment due to anthropogenicactivities has become a serious threat to the ecological system including plants. The present studyassesses the toxicity of nano-CuO on rice (Oryza sativa cv. Swarna) seedlings. Three different levels ofstress (0.5 mM, 1.0 mM and 1.5 mM suspensions of copper II oxide, <50 nm particle size) were imposedand seedling growth performance was studied along control at 7 and 14 d of experiment. Modulation ofascorbate–glutathione cycle, membrane damage, in vivo ROS detection, foliar H2O2 and proline accumulationunder nano-CuO stress were investigated in detail to get an overview of nano-stress response ofrice. Seed germination percentage was significantly reduced under stress. Higher uptake of Evans blueby nano-CuO stressed roots over control indicates loss of root cells viability. Presence of dark blue anddeep brown spots on leaves evident after histochemical staining with NBT and DAB respectively indicatesevere oxidative burst under nano-copper stress. APX activity was found to be significantly increased in1.0 and 1.5 mM CuO treatments. Nevertheless, elevated APX activity might be insufficient to scavenge allH2O2 produced in excess under nano-CuO stress. That may be the reason why stressed leaves accumulatedsignificantly higher H2O2 instead of having enhanced APX activity. In addition, increased GR activitycoupled with isolated increase in GSH/GSSG ratio does not seem to prevent cells from oxidative damages,as evident from higher MDA level in leaves of nano-CuO stressed seedlings over control. Enhanced prolineaccumulation also does not give much protection against nano-CuO stress. Decline in carotenoids levelmight be another determining factor of meager performance of rice seedlings in combating nano-CuOstress induced oxidative damages.
