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.
