Hygromycin resistance gene cassettes were designed to facilitate vector construction for plant transformation. Unique EcoRI, Pstl, and Sacll sites in the coding sequence of a hygromycin B phosphotransferase gene (hph) from Escherichia coli were eliminated. The mutated hph genes were used to form gene cassettes flanked by EcoRI-Sacll-Kpnl-Hindlll sites. Hygromycin resistance of wild-type and mutated hph genes was indistinguishable in E. coli and rice protoplast growth assay.
潮霉素抗性基因盒被设计用于促进植物转化的载体构建。在大肠杆菌的潮霉素 B 磷酸转移酶基因 (hph) 的编码序列中消除了独特的 EcoRI、Pstl 和 Sacll 位点。突变的 hph 基因用于形成两侧为 EcoRI-Sacll-Kpnl-Hindlll 位点的基因盒。在大肠杆菌和水稻原生质体生长测定中,野生型和突变型 hph 基因的潮霉素抗性没有区别。
