Abstract
The invention relates to methods of producing a plant with delayed senescence comprising inducing at least one nucleotide deletion, insertion or substitution into at least one copy of a gene encoding deoxyhypusine synthase (DHS) in the plant, wherein the nucleotide deletion, insertion or substitution decreases the activity of DHS encoded by the gene in the plant. The invention also relates to plants produced by the methods and progeny thereof.
Claims19
A method of producing a plant with delayed senescence relative to a wild-type control plant, the method comprising inducing at least one nucleotide substitution into at least one copy of a gene encoding deoxyhypusine synthase (DHS) in the plant in a codon for at least one amino acid selected from the group consisting of K144, K292, D318, E328, A329, V330, S331, W332, K334, K343 of SEQ ID NO:
- 2, or a corresponding amino acid in another plant species, wherein the nucleotide substitution decreases the activity of DHS encoded by the gene in the plant relative to the activity of DHS in the wild-type control plant so as to delay senescence.
A method of producing a plant with delayed senescence relative to a wild-type control plant, the method comprising inducing at least one nucleotide deletion or insertion into at least one copy of a gene encoding deoxyhypusine synthase (DHS) in the plant in a codon for at least one amino acid selected from the group consisting of K144, K292, D318, E328, A329, V330, S331, W332, K334, K343 of SEQ ID NO:
- 2, or a corresponding amino acid in another plant species, wherein the nucleotide deletion or insertion decreases the activity of DHS encoded by the gene in the plant relative to the activity of DHS in the wild-type control plant so as to delay senescence, and the plant contains at least one copy of the gene encoding DHS without the deletion or insertion.
