Bacillus subtilis possesses three classes of genes, differing by their codon preference. One class corresponds to prophages or prophage-like elements, indicative of the existence of systematic lateral gene transfer in this organism. The nature of the selection pressure that operates on codon bias is beginning to be understood.
