Light scattering and [Ca2+]e oscillations of regA- cells. Light scattering and [Ca2+]e were recorded as outlined in Methods. (a, b) Regular light scattering oscillations with a phase length of roughly 4–5 min but with strongly reduced amplitude as compared to wild type oscillations (see also ). (c) Irregular light scattering changes. (d) Oscillations of cAMP levels in the regA- strain were less pronounced than in the wild type; the graph shows examples of one cAMP oscillation each, determined during one spike of light scattering oscillations.
