det3 Has Reduced Amounts of Cellulose and Is Hypersensitive to Inhibitors of Cellulose Synthase.

(A) Amount of cellulose in 4-d-old etiolated Col-0 and det3 seedlings grown under the indicated conditions. Dry weight of etiolated wild-type and det3 seedlings is not significantly different (Col-0, 43.5 ± 1.2 mg/1000 seedlings; det3, 42.9 ± 1.5 mg). Error bars indicate sd of three independent experiments. PA, phytagar.

(B) Hypocotyl length of 4-d-old etiolated Col-0 and det3 seedlings grown in the absence or presence of the indicated concentrations of IXB and AVG. At least 30 seedlings from each of three independent experiments were measured. Error bars indicate se.
