| 摘要 |
The invention relates to a new type of expression cassettes which, under genetic control, contain regulating nucleic acid sequences a) nucleic acid sequence coding for 4-hydrophenylpyruvate dioxygenase (HPPD) or for one of its functional equivalents; and/or b) at least one nucleic acid sequence (anti-HGD), which can inhibit the homogentisate-dioxygenase (HGD) activity. The invention also relates to vectors which are suitable for the production of plants having an increased tocopherol content, to transgenic plants produced therewith, and to a method for the production of transgenic plants having an increased tocopherol content. |
