Cell elongation and expansion in stem of the mutantbnd2. a-b The longitudinal sections (a) and the cross sections (b) of parenchyma cells in the 2nd to 3rd internodes of WT andbnd2.c-dStatistical analysis of the length (c) and size (d) of the parenchyma cells shown in (a).e-fStatistical 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 andbnd2cells in c and d;n = 68, 107 of WT andbnd2cells ineandf). Bars = 10 μm. The significance of the difference was determined by Student’st-test (***,P < 0.001)
