摘要:
近期研究发现,声波可以激发植物的防卫反应,提高植物抗病性。然而,植物感知声波诱导抗病的分子机制还缺乏深入研究。选定特定频率和振幅的声波处理拟南芥,考察拟南芥与病原细菌丁香假单胞菌互作的影响。结果表明,声波预处理后植株叶片中的细菌生长量相比于对照组降低87.5%。利用转录组分析结果表明,拟南芥共有317个基因发生差异表达,其中有232个上调表达基因,85个下调表达基因,并且这些上调表达基因主要富集于防卫反应相关基因。实时定量PCR结果显示,2个防卫反应关键基因PR1和FRK1显著上调表达,说明声波处理可以通过激活拟南芥的基础防卫反应,增强植物对丁香假单胞菌的抗性。最后,利用MEME软件分析声波处理后上调表达的基因的保守转录元件,鉴定了 “AAXXAGAGAG”等3个特异性响应声波的转录元件。研究结果综合表明声波处理可以明显提高植物的抗性,这为把声波用于作物病害控制奠定了理论基础。
