Pcr and enzyme acitivity check on chitin agar showed that the chitinase gene fragment existed and expressed in the wildtype strains . antagonistic activity test in vitro suggest that the transformants remained the ability to produce antibiotics . the recombinant strains showed an increased biocontrol efficacy against wheat take - all and rhizoctonia sheath blight in greenhouse 对小麦全蚀病和纹枯病的盆栽试验结果表明工程菌株p25113一9的防病作用强于野生菌株,尤其是对小麦全蚀病的防治作用,其防治效果同野生菌株ap113和ap25相比,分别增长了22
