Delta-cadinene synthase, a sesquiterpene cyclase, is an enzyme expressed in plants that catalyzes a cyclization reaction in terpenoid biosynthesis. The enzyme cyclizes farnesyl diphosphate to delta-cadinene and releases pyrophosphate.

Delta-cadinene synthase is one of the key steps in the synthesis of gossypol, a toxic terpenoid produced in cotton seeds. Recently, cotton plants that stably underexpress the enzyme in seeds have been developed using RNA interference techniques, producing a plant that had been proposed as a rich source of dietary protein for developing countries.[1]
