Figure 5. Xylose content in cell wall polysaccharides isolated from stems of 6-week-old mutant plants transformed with the different constructs.

Cell walls were prepared from stems, hydrolyzed in TFA, and the xylose content determined by HPAEC. The nomenclature for the constructs used to transform the irx9 and irx14 plants is explained in Table 1. The bars show average ± SD (n = 4). Averages that are not significantly different (ANOVA, Tukey's test, p>0.05) are indicated with the same letter.
