Abstract
The present invention is based on the discovery that increased growth and yield in plants can be achieved by elevating the level of receptor-like protein kinase (RKN), a member of the receptor-like protein kinase (RLK) family. RKN polypeptide and polynucleotides encoding RKN polypeptide are provided, as are RKN expression control sequences. Also included are methods of producing a genetically modified plant characterized as having increased growth and yield as compared to a corresponding wild-type plant. A method for genetically modifying a plant cell such that a plant produced form the cell will have a modulated yield is also provided. A method of producing a genetically modified plant characterized as having increased expression of a gene product of interest in its roots as compared to the corresponding wild type plant is also provided. The invention also provides plants, plant tissue, and seeds produced by the genetically modified plants of the invention.
