A METHOD OF SELECTIVELY PRODUCING MALE OR FEMALE STERILE PLANTS

A method of producing male or female sterile plants comprising the steps of transforming plant material with a polynucleotide which encodes at least one enzyme which reacts with a non-phytotoxic substance to produce a phytotoxic one, and regenerating the thus transformed material into a plant, where...

Beschreibung
Zusammenfassung:	A method of producing male or female sterile plants comprising the steps of transforming plant material with a polynucleotide which encodes at least one enzyme which reacts with a non-phytotoxic substance to produce a phytotoxic one, and regenerating the thus transformed material into a plant, wherein the said non-phytotoxic substance is applied to the plant up to the time of male or female gamete formation and/ or maturation, so that the non-phytotoxic substance provides for the production of a phytotoxic one which selectively prevents the formation of or otherwise renders the said gametes non-functional, wherein the enzyme is expressed preferentially in either male or female reproductive structures, characterised in that (i) the non-phytotoxic substance is selected from the group consisting of ester derivatives of non-phosphonate herbicides which herbicides are directly phytotoxic to non-green tissue, D-alpha amino acids, peptide derivatives of non-protein D-alpha amino acids, S-enantiomers of aryloxyphenoxypropionates and S-enantiomers of ester derivatives of aryloxyphcnoxypropionatcs and (ii) the enzyme is selected from the group consisting of carboxylesterases, D-amino acid oxidases, D-amino acid dehydrogenases, D-amino acid racemases, 2-arylpropionyl-CoA epimerases, alpha-methylacyl-CoA racemases, thioesterases and acyl-CoA synthetases.
