Patent

CA 2529658

The enzymes of the ACC synthase family are used in producing ethylene. Nucleotide and polypeptide sequences of ACC synthases are provided along with knockout plant cells having inhibition in expression and/or activity in an ACC synthase and knockout plants displaying a staygreen phenotype, a male sterility phenotype, or an inhibition in ethylene production. Methods for modulating staygreen potential in plants, methods for modulating sterility in plants, and methods for inhibiting ethylene production in plants are also provided.

Les enzymes de la famille de l'ACC synthase sont utilisées pour produire de l'éthylène. L'invention concerne des séquences nucléotidiques et polypeptidiques de ACC synthases conjointement avec des cellules végétales inactivées (knockout) présentant une expression et/ou une activité de l'ACC synthase, et des plantes inactivées présentant un phénotype "staygreen", un phénotype à stérilité mâle, ou une inhibition de la production d'éthylène. La présente invention concerne également des procédés permettant de moduler l'aptitude à rester vert dans des plantes, des procédés permettant de moduler la stérilité dans des plantes et des procédés permettant d'inhiber la production d'éthylène dans des plantes.
