The present invention provides a novel promoter that is functional in the seeds of plants, in particular the endosperm and/or aleurone and/or the scutellum. Preferably, the isolated promoter sequence of the invention further modulates the expression of a structural gene in response to the phytohormones ABA and/or GA. Alternatively or in addition, the promoter sequence of the present invention is capable of being repressed or otherwise down-regulated in response to GA. The present invention further encompasses genetic constructs capable of expressing a structural gene operably under the control of the inventive promoter sequence, and transgenic plants carrying the genetic constructs. The promoter sequence of the present invention is particularly useful for modifying the seed traits of plants.
La présente invention concerne un nouveau promoteur fonctionnel dans les semences de plantes, notamment l'albumen et/ou l'aleurone et/ou le scutellum. De préférence, la séquence promoteur isolée de l'invention module également l'expression d'un gène structurel en réponse aux phytohormones ABA et/ou GA. Par ailleurs ou également, la séquence promoteur de la présente invention peut être répressée ou encore régulée négativement en réponse à GA. La présente invention concerne également des constructions génétiques capables d'exprimer un gène structurel de manière fonctionnelle sous la commande de la séquence promoteur de l'invention, ainsi que des plantes transgéniques portant les constructions génétiques. La séquence promoteur de la présente invention est particulièrement utile pour modifier les traits de semences de plantes.
