Thph2 PROTEIN FROM TRICHODERMA HARZIANUM, ZmGLP1-17 PROTEIN FROM ZEA MAYS L., AND METHOD FOR PREPARING TRANSGENIC ZEA MAYS L.

Abstract

Provided are a southern corn leaf blight-resistant Thph2 protein from Trichoderma harzianum, a ZmGLP1-17 protein from Zea mays L., and a method for preparing transgenic Zea mays L. Further provided are a cellobiohydrolase protein Thph2 from Trichoderma harzianum T30, a coding gene for the cellobiohydrolase protein, and use of the cellobiohydrolase protein in inducing a response of a GLP ZmGLP1-17 from Zea mays L. against southern corn leaf blight. Trichoderma harzianum strain OEthph2 overexpressing a Thph2 gene is constructed by a transgenic technique. OEthph2 may induce the expression of the GLP ZmGLP1-17 in roots of Zea mays L. and enhance the resistance of leaves of Zea mays L. to the infection of Cochliobolus heterostrophus. ZmGLP1-17 transgenic Zea mays L. material is constructed. The OEthph2 engineered strain may be combined with the ZmGLP1-17 transgenic Zea mays L. material to synergistically improve a control effect for southern corn leaf blight.
