Amoeba fruiting bodies, light micrograph
Light micrograph of several fruiting bodies of Dictyostelium discoideum social amoebas, or slime moulds. Under favourable conditions, D. discoideum lives as a unicellular organism in the soil. When there is a lack of nutrients, the unicellular amoeba form a multicellular aggregation known as a slug. The cells within the slug differentiate, with some forming a fruiting body, or sorocarp, on a long stalk, which releases spores when mature. Research is ongoing to use D. discoideum as unicellular 'factories' to produce a number of molecules including antibiotics and olivetolic acid, a precursor of tetrahydrocannabinol (THC), the psychoactive substance in cannabis.
