The present invention relates generally to the field of molecular biology and concerns increasing the tocopherol content of a plant relative to a control plant, comprising expressing in a plant at least one polynucleotide encoding a delta-12-desaturase, at least one polynucleotide encoding a delta-6-desaturase, at least one polynucleotide encoding a delta-6-elongase, and at least one polynucleotide encoding a delta-5-desaturase. The present invention also relates to methods for the manufacture of oil, fatty acid- or lipids-containing compositions, and to such oils and lipids as such. 本发明般地涉及分子生物学领域，并且涉及相对于对照植物增加植物的生育酚含量，包括在植物中表达至少种编码Δ-12-去饱和酶的多核苷酸、至少种编码Δ-6-去饱和酶的多核苷酸、至少种编码Δ-6-延伸酶的多核苷酸和至少种编码Δ-5-去饱和酶的多核苷酸。本发明还涉及用于制备油、含有脂肪酸或脂类的组合物的方法，且涉及这类油和脂类本身。
