FIELD: chemistry.
SUBSTANCE: invention relates to biochemistry, particularly to an isolated nucleic acid molecule which codes a polypeptide, having delta-9-elongase activity, as well as a purified polypeptide having delta-9-elongase activity, which codes said isolated nucleic acid molecule. The invention also discloses an expression vector containing said isolated nucleic acid molecule, as well as a host cell, a transgenic plant and a transgenic seed containing same.
EFFECT: invention provides efficient production of polyunsaturated fatty acid-enriched oils.
