Abstract:Excitable nerve cells convert electrical signals into chemical outputs to facilitate the active transport of information across the nervous system. We engineered unicellular microbe S. cerevisiae to directly read and convert local chemical concentrations into a dynamic electrical field that is uniformly distributed across fungi populations. The chemically-excitable dual-feedback gene circuit precisely tunes the expression of active potassium channels, coordinating cyclic firing of the plasma membrane potential… Show more
