FIELD: biotechnology.
SUBSTANCE: invention can be used to obtain carotenoids. Proposed are variants of the polynucleotide possessing the activity of phytoene synthase and geranylgeranyl pyrophosphate synthase. These polynucleotides are used to obtain Yarrowia lipolytica yeast transformants producing β-carotene, canthaxanthin or astaxanthin.
EFFECT: invention provides an increase in the production of carotenoids.
