METHOD FOR CONTROLING THE EXPRESSION OF AN ALLEGIC VARIANT OF A GENE OF INTEREST IN A PLANT PLANT OR CELL, METHOD FOR CONTROLING THE EXPRESSION OF A MUTATION IN A FIRST PLANT, PAIR OF PLANTS, PAIR OF PARENTAL PLANTS FOR GERVER PLANTS A PHENOTYPE, CELL, SEED OR PROGENIE, METHOD FOR SELECTIVELY EXPRESSING A FIRST POLNUCLEOTIDE OF INTEREST IN THE PROGENY OF A STERILE MALE PLANT.

摘要

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.
