Effects of colchicine on 7-d-old wild-type (a), any1 (b), than/+ (c) and prc1-1 (d). Transition and fast elongation zone cells were examined, after transplantation to medium containing 2 mM colchicine for 1.5 h. Cortical microtubules are extensively disrupted and only remnants can be observed in some cells (arrows). These microtubule remnants are longer and exhibit higher density in any1, than/+ and prc1-1 cells, compared to those of wild-type roots (b–d, compare to a). Scale bars: 20 μm
