摘要
β 1 ,3 葡聚糖酶属PR 2类蛋白 ,能催化真菌细胞壁的重要成分—β 1 ,3 葡聚糖和 β 1 ,3 1 ,6 葡聚糖的水解 ,水解的寡糖产物是植物防御反应的重要激发子。β 1 ,3 葡聚糖酶在植物抵抗真菌病害中发挥着不可忽视的作用 ,关于 β 1 ,3 葡聚糖酶特别是其作用机制和基因表达调控的研究取得了突出进展。β 1 ,3 葡聚糖酶基因和其它抗病相关基因的综合利用将成为植物抗真菌基因工程的有效途径。
As one kind of “pathogenesis related proteins', β 1,3 glucanase can hydrolyze (1 3) and (1 3,1 6) glucans of fungal cell walls, and the degrading products are a source of elicitors for plant systematic defense response. Therefore, it is an important hydrolysis contributes to plant fungal disease resistance. Recent years advance on study of β 1,3 glucanase and its related gene offers more detail in the utilization of this enzyme. These include particularly the mechanism of its function as well as gene expression and regulation. The synergistic expression of β 1,3 glucanase and other disease resistance related genes are promising crop improvement on plant fungal resistance.\;
