Exception to the Rule: Genomic Characterization of Naturally Occurring Unusual Vibrio cholerae Strains with a Single Chromosome

Figure 4

Putative recombination event that resulted in Chr1 and Chr2 fusions in NSCV1. Top panel: MS6 Chr1 CDS at the fusion junction and the same location in a putative NSCV1-like intermediate and the MS6 Chr2 circle and the codons at the fusion junction are depicted. The cross-over region between Chr1 and Chr2 is indicated by the long X. A prophage insertion event to the right fusion junction prior or post to Chr 2 fusion is depicted by a green line. Bottom panel: The recombination products after fusion event are shown with NSCV 1 in the middle and an excision product that contains one copy of the cross-over genes with the intervening sequences at the bottom.
