ABSTRACT:
The present invention relates to an isolated transcription factor gene which is expressed in a maturing dicot seed and which encodes a transcription factor protein which targets a promoter of a gene encoding seed storage proteins. One group of such genes binds to 7S globulin (b-phaseolin) or lectin (PHA-L) promoters. Transcription factors identified as Pv Seed Factor-1 (PvSF1) and Vicilin-box Binding Protein-1 (VBP1) have been isolated.
There is also disclosed a method for enhancing or reducing expression of seed storage protein, lectin or oil-protein genes in dicot seed crops comprising transforming a seed crop plant with the transcription factor gene of the invention.
