香菇多糖对植物真菌和病毒病害的抗病机理

Disccusion on the Mechnism of Resistance of the Polysaccharide of Lentinus Edodes against Pathogenic Bacteria and Virus of Plant

香菇多糖(LNT)属于真菌多糖,具有与葡聚糖激发子类似的抑病、抗病活性,可诱导植株或细胞产生并积累抗病性物质,如植保素、几丁质酶等。综述了食用菌香菇中的有效成分香菇多糖对植物真菌及病毒病害抗病机理等方面的研究,为多糖类物质作为杀菌剂的开发和用于防治植物病毒病等病害提供一定的理论依据。

Lentinus edodes, the polysaccharide extracted from one kind of edible fungi. The polysaccharide of lentinus edodes （or lentinan） has some antiviral mechanisms, which can primary blunt virus outside and induce the host resistance （increase chitinase activity and/3-1,3- glucanase activity）. Disccusion on the mechanism of resistance of the polysaccharide of Lentinus edodes against pathogenic bacteria and virus of Plant was made for its extensive application in the future.
