Abstract
The present invention concerns a method for increasing plant yield by modulating expression in a plant of a nucleic acid encoding a Ste20-like polypeptide or a homologue thereof. One such method comprises introducing into a plant a Ste20-like nucleic acid or variant thereof. The invention also relates to transgenic plants having introduced therein a Ste20-like nucleic acid or variant thereof, which plants have increased yield relative to control plants. The present invention also concerns constructs useful in the methods of the invention.
Claims30
A method for increasing plant yield relative to control plants, comprising modulating expression in a plant of a nucleic acid encoding a Ste20-like polypeptide or homologue thereof, and optionally selecting for plants having increased yield.
A method for increasing plant yield relative to control plants, comprising introducing and expressing in a plant a Ste20-like nucleic acid or a variant thereof.
A construct comprising:
- (i) a Ste20-like nucleic acid or variant thereof;
- (ii) one or more control sequences capable of driving expression of the nucleic acid sequence of (i);
- and optionally
- (iii) a transcription termination sequence.
A method for the production of a transgenic plant having increased yield, which method comprises:
- (i) introducing and expressing in a plant or plant cell a Ste20-like nucleic acid or variant thereof;
- and
- (ii) cultivating the plant cell under conditions promoting plant growth and development.
A transgenic plant having increased yield resulting from a Ste20-like nucleic acid or a variant thereof introduced into said plant.
25-26. (canceled)
A method of selecting a plant with increased plant yield relative to a corresponding control plant, comprising utilizing a Ste20-like nucleic acid/gene or variant thereof, or utilizing a Ste20-like polypeptide or homologue thereof, as a molecular marker.
