Escherichia coli strains ECOR2, ECOR3 and K-12 are very closely related in genotype as indicated by multilocus enzyme electrophoresis. We show that they have very different rfb regions indicating that recombination has occurred in this region, and we suggest that it may be associated with niche adaptation.
多位点酶电泳结果表明,大肠杆菌菌株ECOR2、ECOR3和K-12在基因型上密切相关。我们发现它们的rfb区域差异很大,表明该区域发生了重组,并且我们认为这可能与生态位适应有关。
