Induction of cell death by inhibitors of cellulose synthesis. Percentage of dead cells detected by trypan blue staining in hybrid poplar suspension cultures (Non-hab cells) and TA(-)hab cells treated with methanol (MeOH) as a control or with 2.0 μM TA, 5.0 μM DCB or 5.0 μM IXB for 48 h. At least 500 cells were counted for each treatment. The values are representative of four independent experiments.
