The phenotype of NbPAGR-silencing in N.benthamiana. a-b The morphological phenotype of control (a) and NbPAGR-silenced (b) plants. c The monosaccharide composition of control and NbPAGR-silenced cell walls. Values significantly different from the control are indicated with an asterisk (n = 5, t-test, p < 0.005). d-e β-1,4-galactanase treatment of NbPAGR and control cell walls. Solubilized sugars (d) and residual material (e) (n = 3). f Relative expression of NbPAGR-A & NbPAGR-B in silenced and control plants (*: p < 0.01, n = 4). Error bars indicate standard deviation
