Behaviour and pattern formation in a social bacterium
Tâm Mignot, from Institut de Microbiologie de la Méditerrandée in France, will give a talk about "Linking single cell behaviors to multicellular pattern formation: a 'Google Earth' approach in the social bacterium Myxococcus xanthus".
How cell motility shapes multicellular organisms and functions is a major question in developmental biology. However, linking single cell behaviours to multicellular differentiation patterns remains difficult, largely because biological systems are multi-scale and dynamic. In this context, social microbes are attractive models because their multicellular lifestyle can be captured in devices as simple as a petri dish. For example, Myxococcus xanthus, a deltaproteobacterium, moves collectively on surfaces to find preys and develop multicellular fruiting bodies once the nutrients are exhausted. In this talk, I will present recent work that attempts to elucidate how single Myxococcus cells make directional decisions and how they use such regulation to cooperate to their elicit predatory behaviors.
