Abstract excerpt

MAIN CONCLUSION: We have demonstrated that the Arabidopsis FRA9 (fragile fiber 9) gene is specifically expressed in secondary wall-forming cells and essential for the synthesis of the unique xylan reducing end sequence. Xylan is made of a linear chain of β-1,4-linked xylosyl (Xyl) residues that are often substituted with (methyl)glucuronic acid [(Me)GlcA] side chains and may be acetylated at O-2 and/or O-3. The...
