CA 2381316
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 equiva- lents; 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.
La présente invention concerne des cassettes d'expression, qui, sous le contrôle génétique de séquences d'acide nucléique de régulation, comprennent: a) la séquence d'acide nucléique codant pour la 4- hydroxyphénylpyruvate-dioxygénase (HPPD) ou pour un de ses équivalents fonctionnels; et/ou b) au moins une séquence d'acide nucléique (anti-HGD) apte à l'inhibition de l'activité de l'homogentisate-dioxygénase (HGD). Cette invention concerne également des vecteurs convenant à la production de végétaux à haute teneur en tocophérol, les végétaux transgéniques ainsi obtenus, ainsi qu'un procédé de production de végétaux transgéniques à haute teneur en tocophérol.
