Figure 5From: Genome-wide detection and analysis of homologous recombination among sequenced strains of Escherichia coliMosaic operons and genes. Three of six rha genes (rhaB, rhaA, and rhaD) belong to an operon on the reverse strand. This operon is unusual because well-defined recombination events clearly fall within gene boundaries; rhaD contains two dense KC clusters, whereas rhaA and rhaB contain predominantly KS and KO SNDs, respectively. In a nearby operon consisting of fdoG, fdoH, fdoI, and fdhE, there has been a KC intragenic recombination event with fdoG a mosaic, resulting from two recombination events, one of which is shared with fdoH.Back to article page
