Fig. 7From: Secretion of a callose hollow fiber from herbaceous plant protoplasts induced by inhibition of cell wall formationAFM images of surfaces on fibers secreted from protoplasts of white birch (A), tobacco BY-2 (B) and A. thaliana (C). Left images correspond to AFM tapping mode images together with the right graphs indicating the cross-sectioning height information along the lines in the left images. RMS indicates root mean square roughness of the areas at the broken squares in the left images. All scale bars indicate 4 µmBack to article page
