The cloned BBE gene sequences were 94.84% identified with the reported BBE genes in GenBank previously. Based on the cDNA sequences of COR and BBE ,two fragments about 400～500 bp from each gene with lower identity among them were cloned. The fusion gene BC (744 bp) is fused by the PCR technique. Then the promoter CaMV 35S driven, containing'forward BC fusion fragments-reverse pdk intron-reverse BC fusion fragments', plant siRNA expression vector were constructed based on the vectors pHANNIBAL and pART27.The work will lay the foundation for breeding a low morphine and high thebaine poppy.

利用blast及分子生物学软件DNAStar对COR和BBE基因的cDNA序列同源性进行分析比较，分别从各基因中筛选和克隆了一段同源性极低、约400～500 bp的片段；并应用重叠PCR法将其拼接成744 bp的融合基因BC，以中间载体pHANNIBAL和植物表达载体pART27为基础，构建了以CaMV 35S启动子驱动的含有"正向BC融合片段- pdk内含子-反向BC融合片段"的ihRNAi植物表达载体，通过转化野生罂粟，初步研究了以COR和BBE基因为靶标的RNAi对内源吗啡合成的抑制效果，为进一步培育低吗啡高蒂巴因的罂粟种质提供了依据。
