Fig. 2From: Transcriptome analysis reveals the mechanism of internode development affecting maize stalk strengthMicrostructure of the third basal internode of two stiff-stalk (SS) lines and a non-stiff-stalk (NSS) line. A Images of the cross section of the center of the third basal internode. The double-ended arrow indicates the rind width. The red line indicates vascular bundle sheath (VBS) thickness. Scale bar = 200 μm. B–E Rind, rind cell wall, VBS, and VBS cell wall thicknesses at the tasseling stage. Error bars represent the standard deviation (n = 10 for B and D; n = 20 for C and E). Different letters indicate significant differences at the same developmental stage (p < 0.01 by one-way ANOVA)Back to article page
