摘要: 利用已公布的水稻条纹叶枯病毒的序列和siRNA Target Finder软件,获得了168条siRNA片段,利用这些片段在水稻基因组中BLAST(Basic local alignment search tool),最终获得6条与水稻基因组完全不匹配的干扰序列。选择其中的2条,通过化学合成干扰序列,利用pCAMBIA1301质粒构建了RNA干扰载体pASV1301-1,pASV1301-2,并成功地转化EHA105农杆菌,为进一步转化水稻、探索利用RNA干扰技术防治水稻条纹叶枯病奠定了基础。

Abstract: By using the sequence of stripe virus published on line and the software of siRNA Target Finder, we ob - tained 168 siRNA segments.After BLAST Scan of rice genome, 6 segments were selected and 2 were chemically synthe - sized and used to construct of expression vector ( pASV1301 -1, pASV1301 -2) intergratedwith pCAMBIA1301 plasmid.The recombined plasmid was successfully transformed into agrobacterium of EHA105,which lay a foundation for the transfor - mation of rice and the prevention of stripe virus disease of rice by RNA interference.
