| + | We considered whether the <i>luxS</i> gene is a little toxic for GR286, and the bacteria tends to refuse the gene when we added a strong promoter in front of it. So, we planned to use induced expression to reconstruction our expression vector. |

| + | <p> |
| + | The plasmid pWH1520 contains the strong <i>xylA</i> promoter originating, and transcription from this promoter is xylose inducible. So, the gene of interest carries its own ribosome binding sequence (RBS) and translation initiation codon. Based on these points, we redesigned primers. |

| + | Considering the <i>lsrACDB</i> gene is a large fragment (4500bp), we used ClonExpress technique cloning the gene again to improve the efficiency of ligation. We divided the <i>lsrACDB</i> sequence into two parts and cloned them separately. Then we ligated the two segments to the plasmid pWH1520 and transformed it into DH5α. After that, we used PCR to select the positive clones. However, we didn't get a good result. |
