摘　　要：利用绿色荧光蛋白基因gfpmut3标记枯草芽孢杆菌(Bacillus subtilis)的启动子P43;构建1个枯草芽孢杆菌-大肠杆菌穿梭表达载体pP43GFP。结果表明:P43与gfpmut3构成了融合基因,可调控gfpmut3在枯草芽孢杆菌和大肠杆菌中的表达;荧光检测发现,P43在枯草芽孢杆菌和大肠杆菌中具有极强的启动基因表达能力;质粒稳定性测定表明,连续稀释培养55 h后,质粒的稳定性为85%。The P43 promoter from Bacillus was chosen to drive the expression of gfp-mut3 and was cloned into B. subtilis-Escherichia coli shuttle plasmid, the recombinant of plasmid pP43GFP obtained was transformed into recipient strains of E. coli DH5α and B. subtilis. The result showed that gfpmut3 gene driven by P43 could express not only in B. subtilis but also in DH5α and that the stability of pP43GFP was 85% after the continuous diluted cultivation for 55 hours.
