Abstract
This invention provides recombinant cells and transgenic plants that display selectively increased or decreased response to brassinosteroids, resulting in increased yield. Methods of modulating brassinosteroid responses, and of modulating plant phenotypes, are provided.
Claims28
A transgenic plant that comprises a recombinant modulator that modulates expression of a bki 1-type gene, wherein the modulator inhibits expression of a BKI 1-type polypeptide.
A recombinant cell comprising an expression vector that encodes a modulator of a bki 1-type gene, wherein the modulator inhibits expression of a BKI 1 type polypeptide.
A method of modulating a brassinosteroid response in a cell, the method comprising:
- expressing a modulator in the cell, which modulator inhibits expression or activity of a BKI 1-type polypeptide in the cell, and
- wherein said modulator of the BKI 1-type polypeptide or gene derepresses the brassinosteroid response in the cell,
- thereby modulating the brassinosteroid response in the cell.
