摘要: 植物与病原菌互作时,活性氧中间体(reactive oxygen intermediates,ROI)和一氧化氮(NO)参与了植物抗病性的建立。寄主与病原菌非亲合性互作产生二次氧爆发高峰,体内NO增加。许多氧化酶可以催化氧爆发产生ROI。ROI和NO通过氧化还原信号启动寄主细胞局部的过敏性坏死反应和全株系统获得性抗病性。
Abstract: The reactive oxygen intermediates(ROI)and the nitric oxide(NO)play an important role in the establishment of resistance to plant diseases during interactions between hosts and pathogens. The plants produce a biphasic oxidative burst in incompatible interactions,and the concentration of NO increases in plant. Many oxidases may catalyze the generation of ROI.The ROI and NO trigger off the hypersensitive response(HR) in regional cells and the systemic acquired resistance(SAR) in total plant tissues through redox signaling.
