| 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. |

| Keywords: | oligosaccharide elicitor induced resistance mechanism |
