The effect of crude chitinase on three pathogens showed that it could degrade the cell-wall of thepathogens.The crude chitinase could make Fusarium spp and Alternaria spps cell-wall thin andrupture,cell-wall and bioplasm separate,the bioplasm of Rhizoctonia solani distribute asymmetry andbecome vacuole,the cell-wall thin and rupture also.

几丁质粗酶对三种病原真菌菌丝细胞壁的降解作用显示，几丁质酶可使交链孢和镰刀菌菌丝细胞壁变薄、溶解、质壁分离、原生质膨大；丝核菌原生质体分布不均匀、空泡化、细胞壁变薄并出现断裂现象。

Lividans. Using pIJ903 bearing tsr gene as a vector, the two furthermost fragments of the cluster, 4. 0kb and 1. 5kb in size respectively, were inserted into it. To facilitate the detection of gene replacement, apr gene was placed in the middle of the two inserts. OriT from E coli plasmid RK2 was also incoporated into the vector, therefore, pIJ903 derivatives can be mobilized from E.

In S. erythraea, pZW could express reporter genes thiostrepton resistance gene and enhanced green fluorescin gene. And it is more suitable to express exogenous genes in S. erythraea stably.

在糖多孢红霉菌中，pZW可以表达硫链丝菌肽抗性基因和绿色荧光蛋白基因，是更适合在糖多孢红霉菌中稳定表达外源基因的整合型表达载体。

The multi-copy expression vector pZM is a shuttle plasmid which can replicate in Escherichia coli, Streptomyces and S. erythraea. It contains PermE promoter, fd terminator, multiple clone site, thiostrepton and ampicillin resistance genes, and ColE1 ori and pJV1 ori replicons which make the vector replicate in E.
