Regulation of Terpenoid Biosynthesis in Higher Plantss, gibberellins, carotenes, and the chlorophyll pigments with their polyprenyl side-chains, presumably are produced in all higher green plants. Other terpenoids are formed much more selectively by a few species. Some terpenoids are produced in large quantities and others only in traces.
