摘要:

目的 开发一种RUBY辅助的可视化筛选转基因植株并有效指示基因编辑发生的CRISPR/Cas9基因编辑载体GCR。 方法RUBYCas9/gRNA的表达盒偶联到一起得到GCR载体,使用水稻的OsAGO2、OsAGO3、OsAGO7为靶基因,分别构建多基因编辑载体GCR-237-1和多基因编辑载体GCR-237-2,以水稻ZH11(Zhonghua 11)为受体材料进行农杆菌介导水稻遗传转化获得基因编辑植株。 结果 GCR-237-1和GCR-237-2转化入水稻愈伤后,RUBY标记可以有效指示转基因阳性事件,并且稳定转化得到的红色植株的靶基因被高效编辑。 结论 利用基因编辑载体GCR可有效编辑水稻基因且通过肉眼直观观察即可有效指示转基因乃至基因编辑植株。

Abstract:

Objective To develop a RUBY-assisted CRISPR/Cas9 gene-editing vector (GCR) enabling visual screening of transgenic plants and gene-editing events. Method The GCR vector was constructed by coupling RUBY with the Cas9/gRNA expression cassette. Using OsAGO2, OsAGO3, and OsAGO7 in rice (Oryza sativa) as target genes, two multi-gene editing vectors (GCR-237-1 and GCR-237-2) were designed. These vectors were introduced into rice (Zhonghua 11, ZH11) via Agrobacterium-mediated genetic transformation to generate gene-edited plants. Result After the transformation of GCR-237-1 and GCR-237-2 into rice callus, RUBY markers effectively indicated transgenic positive events, and the target genes of stable transformed red plants were efficiently edited. Conclusion The GCR vector enables effective gene editing in rice, and transgenic or gene-edited plants can be rapidly identified through direct visual observation.
