Unicellular organisms have been conventionally thought to conduct their life activities independently within each cell. However, there have been many reports of their multicellular behavior due to cell-cell communication mediated by various substances. This symposium will explore collective behavior of the unicellular microorganism yeast, driven by intraspecies cell-cell communication, and present techniques for metabolite and single-cell analysis to uncover the underlying mechanisms. We will also discuss the survival strategies of unicellular organisms.
