| 摘 要： | 微囊藻毒素(MCs)能够诱导青菜幼苗产生氧化损伤,并进一步抑制青菜幼苗的生长。相比较于单独MCs处理,外源一氧化氮(供体为SNP)预处理能够显著降低青菜幼苗体内活性氧(ROS)水平、减缓脂质过氧化反应,从而可以在一定程度上缓解MCs胁迫对青菜幼苗生长的抑制效应。这说明一氧化氮可能作为信号参与了青菜幼苗对MCs的解毒反应。 |

| Abstract: | Microcystins(MCs) could cause severe oxidative damage and growth inhibition of Chinese cabbage seedling.As compared with MCs treatment,exogenous nitric oxide donor SNP could significantly alleviate the growth inhibition of Chinese cabbage seedling caused by MCs stress through decreasing the level of reactive oxygen(ROS) as well as the concentration of TBARS,which was considered to be an indicator of lipid peroxidation of plasma membrane.These results suggested that nitric oxide might be involved in the anti... |
