Patent

CA 2302385

A DNA sequence is provided, which encodes an enzyme that is the a-subunit of the first isozyme of rice anthranilate synthase (ASA). Transformed plants having a high tryptophan content can be regenerated by culturing the plant cells having introduced therein such a recombinant vector which contains, at a position downstream of a promoter, an inserted DNA fragment carrying the above DNA sequence. In addition, methods of selecting transformed plant cells are disclosed, wherein plant cells transformed with the discloses DNA are resistant to inhibitory concentrations of tryptophan or tryptophan analogues.

La présente invention concerne une séquence ADN capable de coder une enzyme constituant la sous-unité alpha du premier isoenzyme de l'ASA (ligase d'anthranilate du riz). L'invention concerne également un ADN capable de coder une enzyme constituant la sous-unité alpha du deuxième isoenzyme de l'ASA. Il est ainsi possible de prendre un transformant végétal à forte teneur en tryptophane et de le régénérer en cultivant des cellules d'un légume dans lesquelles on a transféré un vecteur de recombinaison construit en intégrant en aval d'un promoteur un fragment d'ADN portant la séquence d'ADN considérée. L'invention concerne en outre un ADN présentant une activité de promoteur sur le gène ASA du riz. Cet ADN convient comme promoteur permettant de transférer un gène étranger intéressant dans le riz ou d'autres végétaux, puis d'exprimer ce gène.
