Methods of making crop plants having higher oil levels in their seeds by
increasing glycolytic flux through over-expression of nucleic acids
encoding phosphofructokinase are provided. The invention may further
comprise the over-expression of nucleic acids encoding a pyruvate kinase
to alter oil content in plant seeds, and monocot cells and plants
transformed with phosphofructokinase, or phosphofructokinase and pyruvate
kinase transgenes.
