Multicopy plasmid RSF1010 and four of its in vitro-constructed derivatives were mobilized by the self-transmissible RP4 plasmid into Azotobacter vinelandii UW. Modifications of the Escherichia coli transformation procedure of Cohen et al. (Proc. Natl. Acad. Sci. U.S.A. 69:2110-2114, 1972) allowed transformation of A. vinelandii strains UW and ATCC 12837 with purified RP4 or RSF1010 deoxyribonucleic acid.
多拷贝质粒RSF1010及其四个体外构建的衍生物被自我传递性质粒RP4转移到维涅兰德固氮菌UW中。对科恩等人(《美国国家科学院院刊》69:2110 - 2114,1972年)的大肠杆菌转化程序进行修改后,可用纯化的RP4或RSF1010脱氧核糖核酸转化维涅兰德固氮菌UW菌株和ATCC 12837菌株。
