The amounts of sugar are represented as average mol% of AIR ± SE of 3 biological and 2 technical replicates (n = 6). Italics numbers with stars indicate mutant values that are significantly different from WT at * P ≤ 0.05, ** P ≤ 0.001 significant level (one-way ANOVA followed by Tukey’s multiple comparison test)
