摘  要:
经基因库序列比对确定花生白藜芦醇合酶基因(RS)中的特异序列(长度约108 bp)。以此为模板设计分别含有SalI和SacI酶切位点的一对上、下游引物,并应用二温式PCR扩增得到该特异短片段。将该特异片段正向连接到pBlueskriptIIKS(+)的多克隆位点上,利用T7 RNA聚合酶在体外转录合成地高辛标记的反义特异短核酸探针。该特异短核酸探针的合成为后续RS基因在花生组织器官中表达的RNA原位杂交研究打下了基础。

摘  要:
The Arachis hypogaea resveratrol synthase(RS) mRNA specific fragment was determined by NCBI BLAST.Primers with the two restriction enzymes of Sal I or Sac I were designed and two-temperature PCR was used to amplify the specific and short fragment.The fragment was eventually linked to the multiple cloning site of vector pBlueskript II KS(+).By means of the T7 promoter in the pBlueskript II KS(+) and using the specific fragment as a templet to synthesize Digoxigenin-labeled antisense specific and short RNA probe in vitro transcription with T7 RNA polymerases.The synthesis of probes laid a foundation for the research of the expression of RS gene in peanut by RNA in situ hybridization.
