Smallest genome clocks in at 182 genes

How small can a genome get and still run a living organism? Researchers now say that a symbiotic bacterium called Carsonella ruddii, which lives off sap-feeding insects, has taken the record for smallest genome with just 159,662 ‘letters’ (or base pairs) of DNA and 182 protein-coding genes. At one-third the size of previously found ‘minimal’ organisms, it is smaller than researchers thought they would find…
