摘要：

寡糖是一类重要的激发子，能诱导植物产生抗病性。对几种寡糖激发子及诱导抗性机理研究进展进行了综述。在植物的细胞膜上有寡糖的受体，寡糖诱导活性氧爆发、引起信号物质NO、H2O2的产生，寡糖激发抗性相关基因的表达，寡糖激发抗性相关酶活性提高，诱导产生植物抗毒素。寡糖通过多种途径诱导植物产生抗病性.

关键词: 寡糖激发子诱导抗病性机理

Abstract:

Oligosaccharides are important elicitors that can induce resistance of plants against pathogens. In this review, we have summarized the kinds of oligosaccharides and the mechanism of plant induced resistance by oligosaccharides. Oligosaccharides could bind to the receptor on plasma membrane, and excite the burst out of active oxygen species （AOS） in plat cell, increase intrcellular NO and H2O2. oligosaccharides could induce expression of related resistance gene, increase activity of related resistance enzyme such as PAL, chitinase and β-1,3-glucanase. Oligosaccharides could induce the productionn of Phytoalexin.

Key words: oligosaccharide , elicitor, induced resistance , mechanism
