Abstract

A plant or plant cell that comprises a stable modification of the genome, wherein the genome modification causes a stable reduction in the amount of mRNA level of a DAHP synthase that is expressed in relatively high amounts in stem tissue of the plant. The plant may have reduced amount of lignin.
