DNA甲基化在植物抗病毒反应中的作用
基本信息
结项摘要
植物病毒病是威胁农业生产的重要病害，研究植物/病原物之间的互作机制有助于采取相应的对策去控制植物病害。DNA甲基化广泛存在于原核生物和真核生物中，植物中DNA甲基化在调节转座子的转录转座、基因表达、植物发育、基因组印记、自交不亲和等方面起着重要作用。最近一些研究表明，植物在面临生物和非生物胁迫时，基因组的甲基化会发生变化，预示着DNA甲基化可能是植物适应逆境胁迫的一种调节机制。本项目拟以烟草N基因与烟草花叶病毒 （TMV）的互作为模式，通过分析烟草受TMV侵染前后基因组甲基化的变化，以期弄清DNA甲基化是否参与N基因介导的对TMV的抗病反应，最终明确DNA甲基化在植物抗病毒反应中的作用。
