Paraquat Resistance of Erigeron genus

实验结果表明，百草枯抗性的机制可能与还原酶（如过氧化物酶同工酶）的差异有关，百草枯抗性主要反映表皮细胞对百草枯的保护强度的差异。百草枯处理后蛋白质组成的变化被认为是由百草枯对植物施加生理胁迫引起的次生现象。

Experimental results suggested the possibilidy that the mechnism of the paracuat resistance in Erigeron philadelphicus,which primarily reflects the difference in the protective strength of the epidermal cells against paraquat,can be explained by the difference in reductases (such as peroxdase isozymes.) The changes seen in the protein composition after paraquat treatment was considered a secondary phenomenon resulting from the physiological stress placed on the plant by paraquat.
