Glucose release and saccharification efficiency of fpgs1 and wild-type plants. Total sugar release (a, b) and the saccharification efficiency (c, d) of fpgs1-1, fpgs1-3, wild type, and complemented FPGS1c plants without (a, c) or with (b, d) acid pretreatment, respectively. A total of 100 plants were used for this analysis. For each biological replicate, mature inflorescence stems of 20 individual plants were pooled and assayed for sugar release and the saccharification efficiency. The data represent the average value of five biological repeats for the mutants and wild type (WT) (±SE). Means with * are statistically significant over WT (Tukey’s test, P < 0.05)
