Lignin is a collection of highly heterogeneous polymers derived from a handful of precursor lignols. Heterogeneity arises from the diversity and degree of crosslinking between these lignols.

Feb 21, 2025 · Lignin, complex organic polymer that, with cellulose, forms the chief constituent of wood. It is second to cellulose as the most abundant organic material on Earth, though it has found relatively few industrial uses other than as fuel.

Nov 14, 2022 · Here, we focus on results that have been obtained by engineering the lignin biosynthesis and branching pathways in forest trees to reduce cell-wall recalcitrance, including the introduction of exotic lignin monomers.

Apr 6, 2021 · Along with the cellulose, the secondary wall of tree cells contain more lignin that pectin as a binding agent. Lignin is found in all plant cells, but the high concentrations found in tree cells are what set it apart from other plants.

In the present review, we systematically introduce the biosynthesis of lignin and its regulation by genetic modification and summarize the main biological functions of lignin in plants and their applications.

Lignins from different tree barks, including Norway spruce (Picea abies), eucalyptus (Eucalyptus globulus), mimosa (Acacia dealbata) and blackwood acacia (A. melanoxylon), are thoroughly characterized.

Mar 7, 2025 · A new book details how lignin once protected algae from UV radiation, then later in evolutionary time became a structural support for trees.

Over the past years, large research efforts have been devoted to engineering lignin amount and composition to reduce biomass recalcitrance toward chemical processing. We review the efforts made in forest trees, and compare results from greenhouse and field trials.

Jul 24, 2019 · Over the past years, large research efforts have been devoted to engineering lignin amount and composition to reduce biomass recalcitrance toward chemical processing. We review the efforts made in forest trees, and compare results from greenhouse and field trials.

Lignin is a chemical compound, which is usually separated from the tree, which is a lot of plants and algae in the second layer is the main component of cell walls. 1819 De Candolle introduced the concept of lignin, this phrase from Latin lignum, meaning trees.
