FIELD: biochemistry.
SUBSTANCE: invention relates to biochemistry, in particular, to a transgenic tobacco plant cell having increased expression or activity of neoxanthin synthase compared to a wild type tobacco plant cell, to a plant, tobacco plant material and a tobacco composition comprising said cell. Also disclosed is a method for increasing the content of carotenoids in a tobacco plant, providing the increased expression or activity of neoxanthin synthase in a plant. Invention also relates to a method for producing a tobacco plant with a higher beta-damascenone content compared with a wild type tobacco plant, providing the increased expression or activity of neoxanthin synthase in a plant.
EFFECT: invention allows efficiently producing a tobacco plant with a high content of carotenoids.
