Male- or female-sterile plant production method, comprising the step of transforming plant material with a polynucleotide that encodes at least one enzyme that reacts with a non-phytotoxic substance to produce a phytotoxic, and regenerate the material thus transformed into a plant , in which said non-phytotoxic substance is applied to the plant until the formation and / or maturation of the male or female gamete, so that the non-phytotoxic substance causes the production of a phytotoxic that selectively prevents the formation of gametes , or renders them nonfunctional, in which the enzyme is expressed in male or female reproductive structures, characterized in that: (i) the non-phytotoxic substance is a D-alpha-amino acid and (ii) the enzyme is a D- amino acid oxidase. |
