Cell elongation and expansion in stem of the mutant bnd2. a-b The longitudinal sections (a) and the cross sections (b) of parenchyma cells in the 2nd to 3rd internodes of WT and bnd2. c-d Statistical analysis of the length (c) and size (d) of the parenchyma cells shown in (a). e-f Statistical analysis of the length (e) and size (f) of the parenchyma cells shown in (b). All values in c-f are shown as mean ± SD (n = 58, 110 of WT and bnd2 cells in c and d; n = 68, 107 of WT and bnd2 cells in e and f). Bars = 10 μm. The significance of the difference was determined by Student’s t-test (***, P < 0.001)
