a Cross sections of control and WOX3aOE internode bases of Internode 2 at the E4 stage. Scale bar = 200 μm. b Cell numbers were determined by counting along the radius at the 12 o’clock position from the outer edge of the pith to the epidermis in cross sections excised from the base of Internode 2 at the E4 stage of control and WOX3aOE transgenic plants. Values are means ± SEs (n = 9). c Acid-insoluble lignin content of three independent WOX3aOE lines and control plants. Hemicellulose content (d) and cellulose content (e) of three independent WOX3aOE lines and control plants. Values are means ± SEs (n = 3). Asterisks represent significant differences determined by Student’s t test. ****p < 0.0001; **p < 0.0021; *p < 0.0332; ns means no significance
