Huge potential exists for improving plant raw materials and foodstuffs via metabolic
engineering. To date, progress has mostly been limited to modulating the expression of …

Because lignin limits the use of wood for fiber, chemical, and energy production, strategies
for its downregulation are of considerable interest. We have produced transgenic aspen …

Lignin quantity and reactivity [which is associated with its syringyl/guaiacyl (S/G) constituent
ratio] are two major barriers to wood-pulp production. To verify our contention that these …

Many complex biochemical pathways in plants have now been manipulated genetically,
usually by suppression or over-expression of single genes. Further exploitation of the …

The ever increasing worldwide use of forest tree products, which coincides with the
diminishing of natural forests, necessitates programs for efficient tree farming. For this …

Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate: coenzyme A
ligase (4CL) has been reported as a means for reducing lignin content in cell walls and …

Background Lignification of secondary cell walls is a major factor conferring recalcitrance of
lignocellulosic biomass to deconstruction for fuels and chemicals. Genetic modification can …

This paper summarizes our previous and current research on genetic engineering of lignin
biosynthesis for the purposes of improving wood pulping and bleaching efficiency. For these …

Enormous progress has been made over the last decade in understanding and
manipulating the pathway for lignin biosynthesis in plants. The roles of most of the genes on …

For the last 20 years, as a complement to biochemical approaches, lignin-modified
transgenic trees have proven to be invaluable tools for deciphering the lignin biosynthetic …
