In vitro cellulose synthase assay using membrane preparations of K. xylinus wildtype and plr mutant cells with UDP-[3H]glucose as substrate. Mutants show an increased cellulose synthase activity. Values are the mean ± standard of three experimental determinations. Letters indicate statistically significant differences compared to wild type (a) or compared to plr15 and bcsAA449T (b) according to two-tailed student t-test (p < 0.05)
