Popis: The stability of a 2μm based plasmid, pLG669-z, was measured in a Saccharomyces cerevisiae strain, grown continuously in a non-selective medium. The apparent stability of the plasmid was found to decrease with increasing growth rate. A model was developed to predict the contributions of segregational instability and growth rate differences to the apparent stability. An increase in segregational instability was the dominant factor in the increased rate of plasmid loss.
