Fig. 3From: The Mediator complex subunits MED25/PFT1 and MED8 are required for transcriptional responses to changes in cell wall arabinose composition and glucose treatment in Arabidopsis thaliana Comparison of cell elongation and cell wall composition in Col, hsr8-1, pft1-2 and hsr8-1pft1-2. a Hypocotyl cell length was measured from scanning electron micrograph images. n = 10 cells each from 5 hypocotyls. **, p < 0.01 comparing hsr8-1 to Col, and hsr8-1 to pft1-2 and hsr8-1 pft1-2 (Student’s t- test). b Monosaccharide composition of cell wall material isolated from 14 day old light grown seedlings (5 biological replicates). Fuc fucose; Rha rhamnose; Ara arabinose; Xyl xylose; Man mannose. . ***, p < 0.001 comparing arabinose levels in Col to hsr8-1, and pft1-2 to hsr8-1 pft1-2 (Student’s t- test). c Compositional analysis of cell wall material isolated from dark grown hypocotyl tissues using FTIR. The data are represented as differences in relative absorbance from wild-type Col. d Principal Components Analyses of FTIR data. Score loadings of PC1, PC2 and PC3 are plotted against the range of wavelengths to show the major varianceBack to article page
