The IDG gene from Ralstonia eutropha encoding the Indole dioxygenase was constructed with PTL12 from specific promoter in cotton fiber to form eukaryote vector which contents the prokaryote promoter of Indole dioxygenase.

• 将来源于Ralstonia eutropha中的靛蓝色素酶基因IDG与从棉花基因组DNA中克隆到的棉纤维特异启动子PTL12相连构建了真核表达载体。
