Inhibition of development in Dictyostelium discoideum by sugars

Sugars such as glucose, maltose, and trehalose, which are metabolized by Dictyostelium discoideum and which enhance vegetative growth, inhibit the development of the slime mold at concentrations which stimulate growth maximally. They block the acquisition of aggregation competence as well as aggregation. The same sugars also inhibit the degradation of preformed glycogen ribonucleic acid, and protein, which is characteristic of development and which occurs when the amoebas are starved by incubation in dilute phosphate buffer.
