摘　　要：几丁质酶对于植物抗真菌病害有重要作用,它可水解真菌细胞壁的重要组成成分———几丁质。正常情况下,植物体内几丁质酶的含量很低,如果将外源几丁质酶基因导入植物,可增强植物抗真菌病害的能力,而将几丁质酶基因与其他防卫蛋白基因一同导入植物,植物抗真菌病害的能力将会大大提高。Chitinase is very important for plants to resist fungus disease, and it can hydrolyze chitin which is main component of fungus cell wall. In general, the content of chitinase in plants is very low. If transferring foreign chitinase into plants, the fungus disease resistance of plants is enhanced . However, transferring chitinase and other defensive protein into plants, the fungus disease resistance is enhanced greatly. In this paper, the biologic characteristic and the effect of resisting fungus disease of chitinase are summarized.
