Global Transposon Mutagenesis and a Minimal Mycoplasma Genome.

Looks at a study that used a global transposon mutagenesis to identify nonessential genes in an effort to learn whether the naturally occurring gene complement is a true minimal genome under laboratory growth conditions. Positions of 2209 transposon insertions in the genomes of Mycoplasma genitalium and Mycoplasma pneumoniae; What these junctions define; What the analysis suggests.
