整合子 (integron)的主要的功能是一些抗生素抗性基因的获得和在不同革兰阴性细菌中间的转移。最近在霍乱弧菌发现的超级整合子 (super -integron ,SI) ,扩大了其在基因进化过程中的作用。霍乱弧菌超级整合子在染色体的一个集中的部位汇集了上百个基因盒 ,后来发现这种结构在其 The major functions of integron are the acquisition of some antibiotic resistance genes and the transfer between different Gram-negative bacteria. The recent discovery of super-integron (SI) in Vibrio cholerae has broadened its role in gene evolution. Vibrio cholerae super integron brings together hundreds of gene cassettes at a concentrated site in the chromosome, and later found that this structure in its
