How Do Cells of Saccharomyces Cerevisiae Behave in a Medium Containing Repressing and Including Carbon Sources

Explore the complex behavior of Saccharomyces cerevisiae cells in media containing repressing and inducing carbon sources in this 92-minute conference talk from the International Centre for Theoretical Sciences. Delve into topics such as diauxie in bacteria and yeast, galactose catabolism, and the evolution of the GAL genetic switch. Examine paradoxes in long-term adaptation and unusual epistatic interactions, and investigate the discrepancies between biochemical and genetic data. Learn about polymorphisms in yeast galactose sensors, growth patterns on various sugar combinations, and gene duplication in the adaptive evolution of genetic switches. Gain insights into the constraints on galactose network induction and the complexities of nutrient decision-making in yeast.
