CA 2680799
Pairs of plants are provided in which complementing constructs result in suppression of a parental phenotype in the progeny. Methods to generate and maintain such plants, and methods of use of said plants, are provided, including use of parental plants to produce sterile plants for hybrid seed production. Also provided are regulatory elements for pollen-preferred expression of linked polynucleotides. Also provided are methods for identifying gene function, methods for testing allelic variants, and methods for repressing transmission of transgenes.
L'invention concerne des paires de plantes dans lesquelles des constructions complémentaires entraînent la suppression d'un phénotype parental dans la descendance. L'invention concerne également des procédés de génération et de conservation de ces plantes, et des procédés d'utilisation desdites plantes, comprenant l'utilisation de plantes parentales pour produire des plantes stériles pour la production de semence hybride. L'invention concerne également des éléments régulateurs de l'expression préférée du pollen des polynucléotides liés. L'invention concerne également des procédés d'identification de la fonction d'un gène, des procédés de test de variantes alléliques et des procédés de répression de la transmission de transgènes.
