From: Transcriptome analysis reveals the mechanism of internode development affecting maize stalk strength

Fig. 1

Rind penetrometer resistance (RPR) and stalk chemistry composition of two stiff-stalk (SS) lines and a non-stiff-stalk (NSS) line. A Stem region subjected to RPR measurement, paraffin sectioning, and RNA-seq sampling. The cross-sectional area of the probe was 1 mm2. Approximately 2 mm of the stem center was separated along the long axis of the cross section. The red arrow indicates the location of the RPR measurement, and the red line indicates the long axis. B RPR of the third basal internode. CF Dry weight per unit length (DWUL), hemicellulose content per unit length (HWUL), cellulose content per unit length (CWUL), and lignin content per unit length (LWUL) of the third basal internode. Error bars represent standard deviation (n = 3). Different letters indicate significant differences at the same developmental stage (p < 0.01 by one-way ANOVA)
