Polycistronic expression of a β-carotene biosynthetic pathway in Saccharomyces cerevisiae coupled to β-ionone production

•The ribosomal skipping sequence T2A is active in S. cerevisiae.•Synthetic β-carotene pathway derived from a single polycistronic gene.•Carotene-producing yeast expressing carotenoid cleavage dioxygenase produces β-ionone.•Action of RiCCD1 dioxygenase on carotenoid-pathway intermediates generates by...
