真菌源几丁质酶在植物抗真菌病害中的应用

摘要

Chitinase,which can degrade most fungal cell walls,prevent or interrupt the fungal infection,colonization and expansion in plants,has attracted a lot attention in fungi disease resistance.In this paper,we reviewed the characteristics of chitinase originated from fungi,the inhibition mechanism to fungi,the resistance evaluation of the transgenic plants,the application of chitinase-producing strains and related products in the biological control,and prospects for the development in the future.%几丁质酶可以降解大多数真菌细胞壁,阻止或中断真菌在植物体内的侵染、定殖和扩展,在抗真菌病害的研究方面受到广泛关注.本文综述了真菌源几丁质酶的特性,对真菌的抑制作用机制,转几丁质酶基因植株的抗性评价,产几丁质酶菌株和相关制剂在生物防治方面的应用,并对其在生产上的发展前景进行了展望.
