Tiniest bacterial genome to date

It’s ~160 kbp in length, is only 16.5% GC, encodes 182 putative open reading frames and belongs to the bacterium Carsonella ruddii, an endosymbiont of psyllids (sap-feeding insects such as aphids). It’s weird. This genome is so reduced that we could be seeing a bacterium on its way to becoming an organelle.
