Abstract

We have extended the method of transposon mutagenesis to the eukaryote, Saccharomyces cerevisiae. A bacterial transposon containing a selectable yeast gene can be transposed into a cloned fragment of yeast DNA in Escherichia coli, and the transposon insertion can be returned to the yeast genome by homologous recombination. Initially, the cloned yeast DNA fragment to be mutagenized was transformed into an E. coli strain containing an F factor derivative carrying the transposable element. The culture was grown to allow transposition and cointegrate formation and, upon conjugation, recipients were selected that contained yeast sequences with transposon insertions. The yeast DNA was removed from the vector by restriction endonuclease digestion, and the transposon insertion was transformed into yeast. The procedure required a minimum number of manipulations, and each transconjugant colony contained an independent insertion. We describe 12 transposon Tn3 derivatives for this procedure as well as several cloning vectors to facilitate the method.
