title: Transposon-based strategies for the identification of essential bacterial genes.
abstract: We present a conceptual review of transposition-based strategies for determining gene essentiality on a one-by-one basis in bacteria. Many of the techniques are described in greater detail in individual chapters of this volume. The second section of this chapter deals with transposition-deletion-based strategies for determining the essentiality of blocks of genes. This latter approach has the potential to experimentally define the minimal required genome for a given organism.
