(?)-Camphene is the major product in?Abies grandis?(grand fir) with traces of other monoterpenoids [1]. In?Pseudotsuga menziesii?(Douglas-fir) there are about equal parts of (?)-camphene and (?)-¦Á-pinene with traces of four other monoterpenoids [2,3]. In?Solanum lycopersicum?(tomato) tricyclene,?beta-myrcene, limonene, and traces of several other monoterpenoids are also formed [4]. See also EC?4.2.3.15?myrcene synthase, EC?4.2.3.16?(4S)-limonene synthase, EC?4.2.3.119?(?)-¦Á-pinene synthase and EC?4.2.3.105?tricyclene synthase.
