We would like to thank the European Community (DGXII) for its support of the OPLIGE "ECLAIR programme (Contract n° AGRE-CT92-0021 )" and TIMBER "FAIR programme (Contract n° FAIR-CT95-0424) (DGXII)" projects. The collaboration of Christine Guidice in the preparation of this chapter is acknowledged.
Noted added in proof: After the writing of this chapter several new results have been obtained concerning the lignin biosynthetic pathway: the gene encoding 4-coumarate 3-hydroxylase has been characterized: Schoch et al. J Biol Chem 276(29):36566-36574, 2001. A new gene encoding a hydroxycinnamyl dehydrogenase converting specifically sinapaldehyde into synapyl alcohol (the SAD gene) has been discovered: Li et al. Plant Cell 13:1-20, 2001. Finally several arguments support the idea that free sinapic acid is not a precursor of monolignols: Harding et al. Plant Physiol 128(2): 428-438, 2002.

Our internal organs, the colon, liver and intestines, help our bodies eliminate toxic and harmful matter from our bloodstreams and tissues. Often, our systems become overloaded with waste. The very air we breathe, and all of its pollutants, build up in our bodies. Today’s over processed foods and environmental pollutants can easily overwhelm our delicate systems and cause toxic matter to build up in our bodies.
