elmo1^−/− has reduced mannose. (A-C) An alcohol insoluble fraction (AIR) from dark-grown seedlings was used to measure, by HPAEC-PAD, neutral sugars content and cellulose. (A) No significant differences between elmo^−/− and WT were detected (unpaired two tailed t-test, P>0.05) for all sugars and cellulose except for mannose. The mannose levels are also shown on a larger scale to the right [numbers below each bar show mean (top) and standard deviation (bottom)]. *P<0.01 (unpaired two tailed t-test). (B) Pectin was measured by extracting uronic acids with ammonium oxalate from the indicated genotype. (C) Total released methanol from AIR preparations indicates degree of pectin methylesterification between the indicated genotype. No significant differences were detected (unpaired two tailed t-test, P>0.05).
