The present invention relates to polypeptides, and polynucleotides encoding therefor, which influence seed dormancy in cereals such as wheat and barley. In particular, the present invention relates to polypeptides with ABA 8'- hydroxylase activity, and polynucleotides encoding these proteins. Also provided are cereal plants which produce seeds that have altered rates of germination, and/or levels of dormancy, when compared to seeds from wild-type plants, as well as methods of producing such plants.
La présente invention concerne des polypeptides et des polynucléotides codant pour ceux-ci, qui influencent la dormance d'une graine chez des céréales telles que le blé et l'orge. En particulier, la présente invention concerne des polypeptides avec une activité ABA 8'-hydroxylase et des polynucléotides codant pour ces protéines. L'invention concerne également des plantes de céréales qui produisent des graines qui ont des taux de germination et/ou des niveaux de dormance modifiés, par comparaison à des graines provenant de plantes de type sauvage, ainsi que des procédés de production de ces plantes.
