一种新型核酸农药设计、制备及递送技术

Abstract

本发明提供一种新型核酸农药设计、制备及递送技术。本发明提供一种具有四面体结构的RNA分子,其利用如下方法构建获得:S1:针对有害生物的靶向基因,设计9个以上siRNA或dsRNA,其中3个以上的siRNA或dsRNA为15‑35bp,6个以上的siRNA或dsRNA为9‑25bp;S2:提供与S1中siRNA互补配对的多核苷酸;S3:将15‑35bp互补配对的siRNA或dsRNA,作为四面体结构顶边的一条边,并将9‑25bp互补配对的siRNA或dsRNA,通过kissing loop序列与9‑25bp互补配对的另一siRNA或dsRNA连接,作为四面体结构底边的一条边。
