Tóm tắt
Trong nghiên cứu này, các gen chitinase mang trình tự peptide tín hiệu như Chi42, syncodChi42-1 và syncodChi42-2 đã được tạo dòng trong vector biểu hiện thực vật pMYV719 và biến nạp thành công vào vi khuẩn Agrobacterium tumefaciens LBA 4404. Trong đó, gen Chi42 là kiểu gen hoang dại từ chủng nấm Trichoderma asperellum SH16. Hai gen syncodChi42-1 và syncodChi42-2 có nguồn gốc từ gen Chi42 đã được tối ưu hóa bộ ba sử dụng để biểu hiện thực vật. Vi khuẩn A. tumefaciens mang các gen chitinase được sử dụng để chuyển gen vào cây lạc (Arachis hypogaea L.) trong các nghiên cứu tiếp theo để cải thiện khả năng kháng nấm bệnh của chúng.
