Streptomyces lavendulae S985 carried two plasmids, pSL1 and pSL2. pSL2 contained all of the pSL1 sequences plus a tandem duplication of 900 base pairs from a region of pSL1. Sequence analysis of the duplication junction suggested that the duplication occurred by recombination between short direct repeats of as little as 5 base pairs.
薰衣草链霉菌S985携带两个质粒,pSL1和pSL2。pSL2包含所有pSL1序列,外加来自pSL1一个区域的900个碱基对的串联重复序列。重复连接点的序列分析表明,重复是由短至5个碱基对的直接重复序列之间的重组发生的。
