查询词典 lysogen

To prove that the cloned DNA fragment can express tryptopanase,a new plasmid pET28C-TnaA , in which the cloned DNA fragment was located downstream of T7 promoter on pET28c was constructed and transformed into host BL21(DE3),a BL21 lysogen of bacteriophage DE3 in which the only promoter known to direct transcription of the T7 RNA polymerase gene is the lacuvS promoter ,which is inducible by IPTG.

为了证明质粒上的基因能表达出有活性的色氨酸酶，将这个DNA片段克隆到PET28c质粒的BamHI和HindⅢ位点上，使该片段受T7 RNA聚合酶的启动子控制，然后转化噬菌体DE3的溶源菌BL21(DE3)。

A lysogen with vt2 gene was obtained after transfecting MC1061 by VT2 phage SHФW1 isolated from sewage.

将噬菌体分离株SHφW1感染MC1061后，经PCR鉴定获得一株溶源菌株(MC1061/SHφW1)。

The Cre gene was cloned from lysogen BM25.8 by PCR. The Cre gene was then inserted in between the CaMV35S-35S double promtor and Nos terminator of PBI525 plasmid after sequencing. The expression box was cut down and inserted into plasmid pBINPLUS to obtain the final fertility-restoring expression vector pBINPLUSCre.

PCR方法从溶原菌BM25.8基因组DNA扩增出Cre基因，克隆测序验证无误后插入PBI525 CaMV35S-35S双启动子和Nos终止子之间，再将表达盒切下插入pBINPLUS质粒相应位点，得到恢复基因植物表达载体pBINPLUSCre。
