Monosaccharide composition values are shown as the mean and average of the relative content of each monosaccharide (in %) of 5 biological replicates. 100% corresponds to the sum of Ara, Gal, Glc and Xyl. cal1, cal2, bm1, and bm3 are in B73 genetic background. cal3, cal4, cal5, cal6, cal7, and cal8 are in A619 genetic background. Asterisk(s) indicate levels of statistical significance between each mutant and corresponding wild-type plant determined by two-tailed unpaired Student t-test at p-value < 0.01 (**), p-value < 0.05 (*).
