Abstract
The present method is useful for the identification of genes, ORF's and other nucleic acid molecules which are essential for the expression of a specific phenotype in microorganisms. The method employs In vitro transposition in conjunction with an chromosomal integration vector containing a specific gene or genetic element whose function is unknown. Subsequent transformation of a recombination proficient host with the vector and growth first under non-integrating conditions and then under integrating conditions, followed by a selection screen for either single or double crossover events results in transformants that may be subjected to phenotypic screens to determine gene function.
