Using the key gene in systematic acquired resistance (SAR) signal transduction, we can introduced the plants own disease-resistance which can gain a broad-spectrum disease resistance. NPR1 genes play an important role in the plant SAR.

• 系统获得性抗性(Systematic acquired resistance, SAR)是植物抵御病原菌侵染的最有效手段,我们可以利用SAR信号传导途径中的关键功能基因来启动园林植物自然防御系统,达到广谱抗病的目的。
