  1. Values are expressed in mg/g cell wall residue. Values in brackets are the SE from four biological replicates (n = 4 plots). GlcA, glucuronic acid; 4-O-MeGlcA, 4-O-Methylglucuronic acid
  2. For each site, asterisks (bold values) indicate significant differences from the wild type using the unpaired Student's t test (*P < 0.05)
