Show more >Plants are built of various specialized cell types that differ in their cell wall compositionand structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterizedby the presence of the heterogeneous lignin polymer that plays an essential role intheir physiology. This phenolic polymer is composed of different monomeric units – themonolignols – that are linked together by several covalent bonds. Numerous studies haveshown that monolignol biosynthesis and polymerization to form lignin are tightly controlledin different cell types and tissues. However, ourunderstanding of the genetic controlof monolignol transport and polymerization remains incomplete, despite some recentpromising results. This situation is made more complex since we know that monolignolsor related compounds are sometimes produced in non-lignified tissues. In this review, wefocus on some key steps of monolignol metabolism including polymerization, transport,and compartmentation. As well as being of fundamental interest, the quantity of ligninand its nature are also known to have a negative effect on the industrial processing ofplant lignocellulose biomass. A more complete view of monolignol metabolism and therelationship that exists between lignin and other monolignol-derived compounds therebyappears essential if we wish to improve biomass quality.Show less >
