Kurzbeschreibung (Abstract)
The most widely used strategy for selection of yeast transformed with episomal plasmids comprises the use of auxotrophic yeast strains in combination with vectors containing complementing prototrophic marker genes. Another approach uses heterologous genes or cassettes which, if present in the vector, render the otherwise sensitive yeast strain resistant to antibiotics. In addition, auto-selection systems for Saccharomyces cerevisiae have been developed that eliminate the requirement for synthetic drop-out media or the use of antibiotics for transformation selection and subsequent plasmid maintenance in expression cultures. Here we describe a combination of host strain and vector system introducing a novel concept of auto-selection systems that allows for easy and robust propagation of host cells deleted in essential genes in supplemented media before being transformed with rescuing plasmids. With that, our approach is favorable over commonly used selection strategies and has major advantage over other auto-selection systems. Our approach complements the auto-selection toolbox already available for S. cerevisiae, thus contributing a novel system that enables the use of complex peptone-based media for protein expression and metabolic engineering approaches. We therefore expect that this new strategy will be of general interest to the yeast research community in academia and industry.
