Hemicellulose molecular weight distribution and cellulose crystallinity index (CrI). Distribution of weight-average molecular weight (M w) of hemicellulose (a) and the average CrI of cellulose (b). CrI values reported are the average of 5 biological replicates from each control group and 10 biological replicates from each transgenic group. Error bars represent standard errors. An asterisk (*) indicates a significant difference between the transgenic and control groups as determined by a Student’s t test (P < 0.05)
