A highly conserved sequence of 210 bp of AtNHX1 gene that encodes a Na+/H+ antiport protein was isolated from A.thaliana,the 210 bp fragment was amplified as RNAi target site and used in construction of RNAi vector,and was inserted into pHANNIBAL as reverted repeat with an intron.The expressional box was linked into the vector of pART27,NPTⅡgene is the screening marker in this vector.

利用RNAi研究植物基因功能，可选择靶基因的一段单一序列使基因家族中的单个成员沉默；也可以选择某一基因家族的多个成员具有的一段同源性很高的保守序列，设计针对这一序列的dsRNA表达载体使多个基因同时沉默，RNAi成为功能基因组学研究的重要手段。
