[début du texte] Flax is a fiber crop producing highly contrasted secondary cell wall structures in the stem. Cells from the inner xylem core have heavily lignified secondary cell walls containing almost 30 % lignin whereas the thick secondary cell walls of the long bast fibers present in outer stem tissues are hypolignified and contain less than 4 % lignin (Day et al., 2005). Despite the existence of these highly contrasted secondary cell wall structures, hardly anything is known about the underlying molecular mechanisms regulating lignin biosynthesis and deposition in flax. In order to increase our knowledge about this process we have created a flax EMS mutant population.
