Male-sterile plants, methods for obtaining male-sterile plants and recombinant DNA for use therein.

摘要

The present invention provides male-sterile plants, characterized in that the said plants have a recombinant polynucleotide integrated into their genome, essentially comprising an inhibitory gene, which, upon proper expression in the anthers of the plant, is capable of inhibiting expression of one or more genes encoding an enzyme involved in the synthesis of chalcone, or one of its precursors.
