A novel three-domain gene from the genus Schizochytrium, expressed as carotene synthase, that encodes a protein with three different enzyme activities: phytoene dehydrogenase (PD) activity, phytoene synthase (PS) activity, and lycopene cyclase (LC) activity Are described herein. An isolated gene encoding carotene synthase, homologues thereof, enzymes encoded by such genes, biologically active portions and homologues thereof, recombinant nucleic acid molecules, increasing the action of such genes or Also described are microorganisms and plants that have been genetically modified to reduce, as well as methods for producing carotenoids and their derivatives, or methods for producing pigmentless microorganisms and lipid products using the knowledge of carotene synthase described herein.
