Abstract
The present invention provides novel polynucleotides, related polypeptides and all conservatively modified variants of a novel transcription factor which is associated with kernel mass in plants. Methods are disclosed to alter the genetic composition of crop plants, enhance kernel size and to improve yield. The invention also includes vectors, cells, and modified plants.
