Distribution on the N. meningitidis strain 8013 genome of 3,655 transposon insertions in an archived collection of mutants. The concentric circles show (reading inwards): insertions in genes (green); genes transcribed in the clockwise direction (red); genes transcribed in the counterclockwise direction (blue); and insertions in intergenic regions (black). Distances are in kbp.
