【摘要】木霉菌是重要的植物病害生防菌,在与植物病原真菌的拮抗过程中可产生一种特殊的化合物——几丁寡糖,几丁寡糖在木霉菌生防中具有多种生物功能.从真菌细胞壁和节肢动物外骨胳中分离的几丁寡糖,可充当化学激发子、诱导植物产生抗性、激发植物的防御系统、提高植物的抗病性.%The fungous Trichoderma is an important microorganism in the biological control of plant
diseases.
A
special
compound,
N—acetyl—chito—
oligosaccharides, could be produced by Trichoderma spp. In antagonism process with plant fungous pathogens. N-acetyl-chito-oligosaccharides are involved in a variety of biological events of Trichoderma. As part of the exoskele-ton of different insects and fungi, they could act as chemical signals to induce resistance, inspire defense system, and to improve resistant ability against plant diseases. 【总页数】3页(194-196)
