Cultured cells of Arachis hypogaea susceptible to induction of stilbene synthase (resveratrol-forming).

Callus cultures were established from cotyledons of Arachis hypogaea. The cultured cells were shown to produce stilbene synthase (resveratrol-forming) if the cells were irradiated with 254 nm UV light. The lag period after which the stilbene synthase activity appeared was similar for cultured cells and intact cotyledons.
