Cellulose biosynthesis pathways (a) and the transcript profiles of selected genes related to cell wall construction between the high and the low WBD types. Transcript levels of, INV (b), HEX (c), PGM (d), UGP (e), SUSY (f) and CesA (g) are shown. RPKM values are plotted on the Y-axis. Numbers on the X-axis represent gene numbers and Arabidopsis homolog gene names listed in Additional file 6: Table S3. The data collected from three technical replicates of each plant were analyzed. Mean values and standard deviations are shown with error bars. Asterisks or double asterisks indicate significant differences at p < 0.05 or p < 0.01, respectively
