Abstract

The invention relates to transgenic plants exhibiting increased cell wall content. In one embodiment, transgenic plants engineered to over-express fructokinase (FRK) or both FRK and sucrose synthase (SuSy) are provided. The FRK+SuSy double-transgenic plants of the invention consistently exhibit enhanced cell wall polymer deposition.
