grex
The multicellular aggregate formed by cellular slime moulds (Acrasidae) : the slug-like grex migrates, showing positive phototaxis and negative gravitaxis, until culmination (the formation of a fruiting body) takes place. Coordination of the activities of the hundreds of thousands of individual amoebae that compose the grex may involve pulses of cyclic AMP in Dictyostelium discoideum, a species in which cAMP is the chemotactic factor for aggregation.
