It is a subject of this invention to isolate a gene group of enzymes involved in the biosynthesis of vitamin E of Para rubber tree, and to determine the base sequence of each gene. According to this invention, genes encoding enzymes involved in the vitamin E biosynthesis were isolated from Para rubber tree and the base sequences of these genes were determined. Since vitamin E is an antioxidant existing in nature, it is expected that transformation of a plant by using the genes obtained in the invention would result in an increase in the vitamin E content of the plant and, in its turn, contribute to the prevention of rubber from aging.
本发明的一个主题是分离出参与帕拉橡胶树维生素 E 生物合成的酶基因组,并确定每个基因的碱基序列。根据本发明,从 Para 橡胶树中分离出了编码参与维生素 E 生物合成的酶的基因,并确定了这些基因的碱基序列。由于维生素 E 是自然界中存在的一种抗氧化剂,利用本发明获得的基因对植物进行改造,可望增加植物的维生素 E 含量,进而有助于防止橡胶老化。

The invention relates to a method for producing transgenic plants and/or plant cells having an elevated vitamin E content, said transgenic plants and/or plant cells having a serine-acetyltransferase (SAT) content and/or activity which is modified in relation to the wild type, and/or a modified thiol compound content. The invention also relates to the use of nucleic acids coding for a SAT, for producing transgenic plants or plant cells having an elevated vitamin E content. The invention further relates to a method for producing vitamin E by cultivating transgenic plants or plant cells having a modified SAT content in relation to the wild type.
本发明涉及一种生产维生素 E 含量提高的转基因植物和/或植物细胞的方法,所述转基因植物和/或植物细胞的丝氨酸乙酰转移酶(SAT)含量和/或活性相对于野生型有所改变,和/或硫醇化合物含量有所改变。本发明还涉及使用 SAT 的编码核酸生产维生素 E 含量增加的转基因植物或植物细胞。本发明还涉及一种通过培养 SAT 含量相对野生型有所改变的转基因植物或植物细胞来生产维生素 E 的方法。
