Abstract
The disclosure relates to methods for modulating plant growth and organogenesis using dominant-negative receptor-like kinases.
Claims20
A method for increasing plant yield relative to corresponding wild type plants comprising modulating expression in a plant of a nucleic acid encoding WAKL14 polypeptide or homolog thereof, and selecting for plants having increased yield or growth on a nutrient deficient substrate.
A construct comprising:
- (i) a WAKL14 polynucleotide, homolog or a variant thereof, (ii) one or more control sequences capable of driving expression of the WAKL14 polynucleotide, homolog or a variant of (i), and optionally (iii) a transcription termination sequence.
A method for the production of a transgenic plant having increased yield or growth relative to a corresponding wild type plant on a nutrient deficient media, which method comprises:
- (i) introducing and expressing in a plant or plant cell a WAKL14 polynucleotide, homolog or a variant thereof;
- and (ii) cultivating the plant cell under conditions for promoting plant growth and development.
A transgenic plant having increased yield relative to a corresponding wild type plant under nutrient or light deficient conditions, said increased yield resulting from a WAKL14 polynucleotide, homolog or a variant thereof introduced into said plant.
