Patent

CA 2318476

Isolated genes which are expressed during plant senescence are provided. In particular, a gene is provided which encodes a receptor-like protein kinase which is preferentially expressed in plant leaves early in the process of plant senescence. Additionally, a gene encoding S-adenosyl methionine synthase which is expressed during the process of plant senescence is provided. Promoters from genes expressed during plant senescence are provided and operably linked to a foreign gene to provide developmental-specific expression of the foreign gene in a transformed plant.

L'invention concerne des gènes isolés qui sont exprimés pendant le vieillissement des plantes. En particulier, l'invention traite d'un gène qui code une protéine kinase de type récepteur qui est, de préférence, exprimé dans les feuilles des plantes au début du processus de sénescence des plantes. En outre, l'invention a aussi pour objet un gène codant la synthase du S-adénosyl méthionine qui est exprimé pendant le processus de sénescence des plantes. Enfin, l'invention traite aussi de promoteurs de gènes exprimés pendant le vieillissement de la plante qui sont liés, de manière opérationnelle, à un gène étranger pour assurer l'expression spécifique au développement du gène étranger dans une plante transformée.
