The invention discloses a quorum sensing signal molecule DSF degradation gene fadT, the nucleotide sequence of which is shown in SEQ ID NO.1. The invention clones a new gene-DSF degrading enzyme encoding gene fadT responsible for fatty acid degradation from Cupriavidus pinatubonensis strain HN-2. After the encoding gene fadT is expressed in Xanthomonas campestris pv. campestris, Xcc, it can significantly reduce the pathogenicity of Xcc, and has a significant control effect on black rot caused by Xcc. |
