Résumé : The progressive colonization of land by plants has been possible mainly owing to the developmentof lignified cell walls that allow water conduction through tracheary elements and the uprightgrowth. Lignin is a complex aromatic polymer that is embedded in secondary cell walls of vascularplants. However, the ability to synthesize lignin precursors is much more ancient as the ligninbiosynthesis machinery and lignin-like material are present in nonvascular plants including somealgae and bryophytes. This chapter focuses on recent knowledge in the distribution of lignin as wellas in lignin biosynthesis and polymerization genes across the plant kingdom. The amazing variabilityand flexibility of lignin structure and composition are also reviewed.
