Patent

CA 2336487

The present invention relates to a novel gene (the "ran 1" gene), identified in Arabidopsis, encoding an early-acting regulator in the ethylene gas signaling pathway, and to antagonist responsive mutants controlling copper transport in the plant. It further relates to the manipulation of the ran1 or the protein expression product of the gene to modulate the ethylene response in plants, thereby permitting the regulation and controlled alteration of a variety of plant growth and developmental processes, including germination, cell elongation, flower and leaf senescence, abcission, fruit ripening and insect resistance.

La présente invention a trait à un nouveau gène (le gène "ran 1"), identifié chez Arabidopsis, qui code pour un régulateur précoce de la voie de signalisation de l'éthylène gazeux, et à des mutants réagissant à un agoniste qui régulent le transport de cuivre dans la plante. L'invention a en outre trait à la manipulation de ran1 ou du produit d'expression protéinique du gène pour moduler la réaction à l'éthylène chez des plantes, ce qui permet de réguler et de modifier de manière contrôlée divers processus de croissance et de développement des plantes, notamment la germination, l'allongement des cellules, la sénescence des fleurs et des feuilles, l'abscission, le mûrissement des fruits et la résistance aux insectes.
