Abstract excerpt
Xylan is a major hemicellulose in the secondary walls of vessels and fibers, and its acetylation is essential for normal secondary wall assembly and properties. The acetylation of xylan can occur at multiple positions of its backbone xylosyl residues, including 2-O-monoacetylation, 3-O-monoacetylation, 2,3-di-O-acetylation and 3-O-acetylation of 2-O-glucuronic acid (GlcA)-substituted xylosyl residues, but the...
