Figure 2

(a) Confocal images of stem sections from the stem base of six-week-old greenhouse grown plants stained with calcofluor white. Scale bar, 50 μm. (b) TEM of basal stem fibre cell walls of sections equivalent of a. Scale bar, 2 μm. (c) Secondary wall thickness measured between two adjacent cells in TEM images as in b. Error bars represent s.e., n≥498 cells from four plants. ***P value<0.001, Student’s t-test. (d–g) Scanning electron microscope images of seeds, showing aberrant columella shape in stl1stl2 mutants. (h–m) Adherent mucilage stained with ruthenium red (h,i) and cellulose stained with pontamine fast scarlet 4B (j–m). Scale bars, 100 μm in d,e,h–m; scale bars, 10 μm in f,g.
