Abstract
Among the ecosystem services provided by forests, wood provisioning takes a central position. Wood and derived products have played a critical role in the evolution of human kind and demand for raw material is increasing in a foreseeable future. Wood is used for energy production, construction and a wide variety of products for which different properties are required. Anatomical, chemical and physical properties of wood are determined through a complex process called xylogenesis controlled by internal and external signals and occurring during the life of the tree. In this chapter we describe i / how wood is formed and ii / the different factors controlling this developmental process , with emphasis on the molecular machinery involved, iii / the functions of wood and iv / the biotechnology approaches developed to improve wood biomass production and properties genetically.
