Effect of TKA on the cell morphology of Xoo. (A) Morphology of representative Xoo cells observed by using transmission electron microscopy. (B) Morphology (up) and height (down) of representative Xoo cells observed by using atomic force microscopy. Control, a representative of Xoo cells untreated with methanol or TKA. TKA, two representative of Xoo cells treated with 54 μg/mL TKA for 24 h. MeOH, a representative of Xoo cells treated with methanol (0.3%, v/v) for 24 h. Fifty Xoo cells were observed in each treatment. Each treatment was repeated three times.
