Figure 6. Monosaccharide content of FRB1 and frb1 seedlings.

A. Uronic acid levels in ammonium oxalate (AO) soluble fraction and in acid soluble (1 M H₂SO₄, UA-Acid) fraction. Levels for AO soluble fraction are significantly different with p<0.05 for all three frb1 lines compared to wild-type B. Neutral sugar content of extracted cell walls from FRB1 and frb1 seedlings. Abbreviations: Rha, rhamnose; Fuc, fucose; Ara, arabinose; Xyl, xylose; Gal, galactose; Glc, glucose. Error bars represent standard deviations with a sample size of 4 and 3 for Figures A and B, respectively. Levels of arabinose are significantly different with p<0.05 for all three frb1 lines compared to wild-type
