PagWRKY40基因在调控杨树抗虫性中的应用
By overexpressing the PagWRKY40 gene in poplar trees and using Agrobacterium tumefaciens-mediated genetic transformation technology, transgenic poplar trees were constructed. This solved the problems of low efficiency in poplar pest control and the limitations of exogenous gene application in existing technologies, and achieved significant enhancement of insect resistance and improved activity of defense enzymes.

AI Technical Summary
Existing technologies for controlling poplar pests suffer from low efficiency, high cost, environmental pollution, and significant impact on non-target organisms. The application of exogenous insect-resistant genes in poplars is limited, and pests are prone to developing resistance.
The insect resistance of poplar was improved by overexpressing the PagWRKY40 gene. Transgenic plants were constructed using Agrobacterium tumefaciens-mediated genetic transformation. The PagWRKY40 gene was used as a positive regulatory gene in response to insect pest stress to enhance the insect resistance of poplar.
The PagWRKY40 gene significantly enhances the insect resistance of poplar trees without affecting their growth, manifested in its antifeedant effect against the fall webworm and increased activity of defensive enzymes, thereby enhancing the plant's insect resistance.
