    • Improved Use of a Public Good Selects for the Evolution of Undifferentiated Multicellularity 

      Koschwanez, John H; Foster, Kevin R; Murray, Andrew W. (eLife Sciences Publications, Ltd, 2013)
      We do not know how or why multicellularity evolved. We used the budding yeast, Saccharomyces cerevisiae, to ask whether nutrients that must be digested extracellularly select for the evolution of undifferentiated ...

    • Nutrient Shielding in Clusters of Cells 

      Lavrentovich, Maxim Olegovich; Koschwanez, John H; Nelson, David R. (American Physical Society, 2013)
      Cellular nutrient consumption is influenced by both the nutrient uptake kinetics of an individual cell and the cells' spatial arrangement. Large cell clusters or colonies have inhibited growth at the cluster's center due ...

    • Sucrose Utilization in Budding Yeast as a Model for the Origin of Undifferentiated Multicellularity 

      Koschwanez, John H; Foster, Kevin R.; Murray, Andrew W. (Public Library of Science (PLoS), 2011)
      We use the budding yeast, Saccharomyces cerevisiae, to investigate one model for the initial emergence of multicellularity: the formation of multicellular aggregates as a result of incomplete cell separation. We combine ...
