Novel genome architecture of Δorc5 strain. (A) Scheme for outcome of recombination between sod1 and sod2 genes to split the main chromosome (+pHV4) and generate two new chromosomes (new chr 1 and new chr 2). (B) PFGE and Southern blot confirming two new chromosomes in Δorc5 strain. Intact genomic DNA of wild isolate DS2, WT H26 and Δorc5 H1689 strains was probed with sod1 and sod2 sequences. (C) Recombination of sod1 and sod2 genes in Δorc5 strain H1689 was confirmed by end-point PCR using primers to unique sequences flanking sod1 and sod. The identity of the PCR products was validated by DNA sequencing.
