植物在与病原菌的长期相互作用中,逐渐发育出自我防御响应体系,当受到微生物病原菌侵染时,会启动防御相关基因表达,产生的防御反应使植物免受微生物病害感染.这种防御响应是通过植物细胞表面上的受体蛋白与病原菌激发子相互结合,使寄主植物识别侵染微生物,并通过信号传导网络在细胞内传递感染信息,启动抗性基因表达,产生防御反应.研究证明,寡糖能够作为外源性激发子诱导植物产生防御响应,因此,寡糖作为生物农药在微生物病害防治中具有十分重要的作用.
植物在與病原菌的長期相互作用中,逐漸髮育齣自我防禦響應體繫,噹受到微生物病原菌侵染時,會啟動防禦相關基因錶達,產生的防禦反應使植物免受微生物病害感染.這種防禦響應是通過植物細胞錶麵上的受體蛋白與病原菌激髮子相互結閤,使寄主植物識彆侵染微生物,併通過信號傳導網絡在細胞內傳遞感染信息,啟動抗性基因錶達,產生防禦反應.研究證明,寡糖能夠作為外源性激髮子誘導植物產生防禦響應,因此,寡糖作為生物農藥在微生物病害防治中具有十分重要的作用.

Defense response system has been developed in the long-term interaction between host plant and phytopathogen. Defense-related genes in plant cells would be expressed upon host plant being attacked by pathogen, resulting in a suit of defense reaction preventing plant from microbial infection. Such defense response was initiated by binding of pathogenic elicitor to receptor on the plant cell surface, leading to the recognition of microbial infection, expression of defense genes and initiation of defense reaction through signal transduction cascade. It has been certificated that plant defense response could be elicited by exogenous oligosaccharide. Therefore, the oligosaccharide as a biological pesticide plays an important role in the control of microbial diseases.
