植物诱导抗病技术在病害防治领域的应用

The application of plant induced resistance technology in disease control

植物受到病害侵染后,依赖信号传导过程表现出抗性,实际应用中,植物诱导抗病技术的常见措施包括交叉保护、根际微生物诱导产生抗性和直接施加激发子3种方法。这些措施发挥作用时涉及的机制通常为诱导次生代谢物质产生,如植物激素、木质素、胼胝质和植保素等。未来,大型分析仪器、高通量筛选平台的建立以及基因技术的发展都将推动这一技术的发展。

After pathogen infection,the immune responses of plants depends on signal pathway. In practical application,the common measures of plant inductive resistance technology include cross protection,inoculating rhizosphere microorganisms and exerting elicitors directly. The mechanism of these measures is inducing the accumulation of secondary metabolism substance,such as phytohormone,lignin,callose and phytoalexin. In the future,with the development of genomics,high-throughout screening technique,and large-scale analyzing instrument,this technology will achieve great breakthroughs ceaselessly.
