Abstract

We will test the effects of pertubations in the dynamics of the cAMP relay system on Dictyostelium morphogenesis. We will perturb the kinetics of the cAMP relay reaction by (1) using mutants defect in or expressing cAMP receptors of altered cAMP affinity. (2) By titrating the level of cAMP phosphodiesterase in synergy experiments between wild type and phosphodiesterase null cells. (3) By microinjection of cAMP pulses of variable duration, amplitude and frequency in slugs to interfere with endogenous cAMP signalling. We will measure wave propagation and cell movement in GFP expressing cells. Essential to the interpretation of the results and design of the experiments is the development of computer models for cAMP relay and cell movement during mound and slug formation.
