DNASeq of different Mycoplasma pneumoniae isolated clones presenting a genomic deletion produced by a multi-recombinase engineering protocol
Ontology highlight
ABSTRACT: We developed a multi recombinase engineering rationale, that combines oligonucleotide recombineering with the selective capacity of antibiotic resistance via transient insertion of selector plasmids. We tested this method in Mycoplasma pneumoniae, a bacterium with a very inefficient native recombination machinery. A wide variety of targeted genome modifications were carried out. We did whole genome sequencing of some clones to confirm that the engineering method is not mutagenic and ensure that genome modifications only occurred at the intended loci. Specifically we sequenced clones carrying 1 kb deletion at 4 different chromosomal locations (i.e., M129-GP35-PtetCre Δ1kbmpn088::lox scar, M129-GP35-PtetCre Δ1kbmpn256::lox scar, M129-GP35-PtetCre Δ1kbmpn440::lox scar, M129-GP35-PtetCre Δ1kbmpn583::lox scar), a clone carrying a 30 kb deletion (M129-GP35-PtetCre Δ30kbNE region::pLoxPuro) and a clone carrying a 5.5 kb deletion that was complemented with the two essential genes found in this area (M129-GP35 Δ5.5kbmpn633-mpn638::mpn636-637lox scar)
