In order to develop a procedure for transformation of the industrial yeast Torulaspora delbrueckii, we have constructed a set of recombinant plasmids carrying Saccharomyces cerevisiae ARS and 2 microns origin of replication and kanamycin-G418 resistance gene of Tn903(601) as a selective marker. In this paper we show that S. cerevisiae ARS vectors can replicate autonomously and that vectors bearing the whole S. cerevisiae 2 microns sequence yield stable transformants. We also present evidence to show that 2 microns vectors undergo an FLP-mediated inter- and intramolecular recombination, which suggests that T. delbrueckii can support the amplification and partition mechanisms of these plasmids.

Abstract
In order to develop a procedure for transformation of the industrial yeast Torulaspora delbrueckii, we have constructed a set of recombinant plasmids carrying Saccharomyces cerevisiae ARS and 2 microns origin of replication and kanamycin-G418 resistance gene of Tn903(601) as a selective marker. In this paper we show that S. cerevisiae ARS vectors can replicate autonomously and that vectors bearing the whole S. cerevisiae 2 microns sequence yield stable transformants. We also present evidence to show that 2 microns vectors undergo an FLP-mediated inter- and intramolecular recombination, which suggests that T. delbrueckii can support the amplification and partition mechanisms of these plasmids.Pubblicazioni consigliate
