Glucuronic acids in Arabidopsis thaliana xylans exist in 4-O-methylated (MeGlcA) and non-methylated (GlcA) forms at a ratio of about 3:2. The matrix-assisted laser desorption/ionization mass spectrometry analysis of the endoxylanase liberated acidic

O-Acetylglucuronoxylans (AcGX) in Arabidopsis thaliana carry acetyl residues on the 2-O and/or 3-O positions of the xylopyranosyl (Xylp) units, but the distribution of different O-acetylated Xylp units is partly unclear. We studied a possible correla

Publikováno v: Journal of integrative plant biology. 57(4)

Secondarily thickened cell walls of water-conducting vessels and tracheids and support-giving sclerenchyma cells contain lignin that makes the cell walls water impermeable and strong. To what extent laccases and peroxidases contribute to lignin biosy
