Abstract: In order to screen the xylem tissue specific and strong function promoter,three plant expression vector pMDCesAP-GUS,pJCesAP-GUS,pDMDCesAP-GUS,fused with GUS report gene and MDCesA promoter,JCesAP promoter,DMDCesAP promoter (including two series MDCesAP promoter) acquired earlier,are transformed to poplar by agrobacterium mediated transformation.With qualitative and quantitative fluorescence detection of GUS activity,the three promoter in transgenic plants expressing ability and level are detected.Fusion of the screened xylem specific promoter and insect-resistant gene will improve the poisonous protein expression in the xylem of the quantity,which is of great significance for prevention and control of boring beetles.

Key words: Xylem specific promoter, Screening, GUS reporter gene, Fluorescence quantitative detection
