Lack of functional FKF1 results in increased cellulose content. A, Crystalline cellulose content of Col-0, c1,c3, and llf leaves from plants grown under long-day (top) and short-day ( bottom) conditions. Statistically significant difference between different groups was determined by one-way ANOVA. Means not sharing the same letter are significantly different (P < 0.05). B and C, Cell wall composition analysis of leaf (B) and stem (C) samples from 12-week-old Col-0 and fkf1-t plants (Gluc. Acid: GlcA, Galac. Acid: GalUA). Data shown are an average of three independent biological replicates with three technical replicates. Error bars represent sd (n = 9). Statistically significant differences were determined by Student’s t test (*P < 0.05; **P < 0.01).
