(p.116) 10 Dictyostelium, the Amoeba and the Slug
Life Under the Sun

Pete A. Ensminger

Yale University Press

This chapter reveals the discovery and different stages in the life cycle of Dictyostelium discoideum, the role of cAMP in intercellular communication, and the porphyrin photoreceptor in Escherichia coli. The significance of phototaxis and chemotaxis in the amoeba and the slug in controlling their movement is also discussed. The action spectrum of the amoeba and the slug indicates the use of different pigments to control phototaxis. Sorocarp, developed from the slug, has great adaptive value and eventually germinates and begins life anew as an amoeba.

Keywords:   Dictyostelium discoideum, intercellular communication, porphyrin, Escherichia coli, phototaxis, chemotaxis, sorocarp
