摘要:

基因编辑技术已成为当前一个重要的分子工具,通过定向改造基因组序列,在基因功能分析和作物遗传育种等方面具有广泛应用。随着基因编辑技术的快速发展,当前其可对受体生物实现几乎无痕编辑,这增加了对基因编辑产品的检测难度。因此,建立基因编辑产品的检测方法,有利于加强对市场上基因编辑产品的监管。以OsWx基因CRISPR/Cas9基因编辑材料为研究对象,设计编辑位点的特异性引物和探针进行TaqMan实时荧光定量PCR(TaqMan-qPCR)检测。研究所建立的检测体系具有良好的特异性和灵敏度,能够有效地区分OsWx单碱基突变体与野生型水稻。

Abstract:

Gene editing technology currently has become an important molecular tool, which can selectively modify genome sequences and has wide applications in gene function analysis and crop genetic breeding. Due to the rapid development of gene editing technology, gene editing techniques can perform almost seamless editing on receptor organisms, which increases the difficulty of detecting the gene editing product. Therefore, the establishment of detection methods for gene editing products is conducive to strengthening market supervision of the gene editing product. This study was based on TaqMan real-time fluorescence quantitative PCR (TaqMan-qPCR) technology for detection to design specific primers and probes for the editing site of OsWx gene by developed with CRISPR/Cas9. In this study, the detection system had good specificity and sensitivity, and could effectively distinguish OsWx single base mutants from wild-type rice.

Key words: gene editing, TaqMan-qPCR, CRISPR/Cas9, OsWx
