Patent

CA 2504947

The present invention provides compositions and methods for regulating expression of nucleotide sequences in a plant. Compositions comprise a novel nucleic acid sequence for a promoter which is induced by abiotic stress and the coding sequence natively associated with said promoter sequence. A method for expressing a heterologous nucleotide sequence in a plant using said promoter sequence is also provided. The methods comprise transforming a plant cell to contain a heterologous nucleotide sequence operably linked to the promoter of the present invention and regenerating a stably transformed plant from said transformed plant cell.

La présente invention concerne des compositions et des méthodes permettant de réguler l'expression de séquences nucléotidiques dans un végétal. Lesdites compositions comprennent une nouvelle séquence d'acide nucléique d'un promoteur qui est induit par un stress abiotique et la séquence codante associée à l'origine à ladite séquence de promoteur. L'invention concerne également une méthode permettant d'exprimer une séquence nucléotidique hétérologue dans un végétal à l'aide de ladite séquence de promoteur. Lesdites méthodes consistent à transformer une cellule végétale afin qu'elle contienne une séquence nucléotidique hétérologue liée de manière fonctionnelle au promoteur selon la présente invention et à régénérer un végétal transformé de manière stable à partir de ladite cellule végétale transformée.
