Depending on conditions, a B. subtilis cell can initiate one out of various distinct differentiation processes to cope with changing environmental conditions. One of these differentiation processes is natural competence that allows cells to adsorb exogenous DNA and subsequently incorporate it into its chromosome by homologous recombination. Due to competence development, the genome of B. subtilis can be easily manipulated, and this has contributed to B. subtilis being a model system. In this chapter, we describe some of the most common genetic tools that can be used in combination with natural competence to tailor the genome of B. subtilis.
