Abstract: "Soybean Mosaic Virus(SMV) is belonging to Potyvirus.The disease caused by SMV is very popular,results in 10%-30% yield loss and exerts heave impact on soybean yield and quality.The pathogenicity of different virus strains varied with their nucleotide sequences.The utility of resistant varieties is the most economic pathway to control SMV.The resistant lines derived from conventional breeding material have narrow resistance spectrum,the resistance loss easily with the mutation of SMV strains.Acquired resistance based on RNA inference(RNAi) is a novel strategy to improve the plant resistance to virus.In this study,SMV isolate from Wuhan field was made sequence analysis,CP and Nib fragment were isolated based on homologous PCR,the fragment in most conserved region was chosed to construct RNAi vectors by use of gateway technique.The construct will be used in further transformation to improve soybean resistance to SMV."

Key words: Soybeanmosaic virus, RNA inference, Gateway technique, Vector construction
