Table 1.
Preferential Orientation of Cortical MT Arrays in Wild-Type and Mutant Root Tip Cells
| Orientation | Wild Type | ton1 |
|---|---|---|
| Transverse | 62.7% | 21.9% |
| Longitudinal | 29.3% | 19.9% |
| NP | 8.0% | 58.2% |
| Total cells | 225 | 306 |
The preferential orientation of the cortical interphase MT array was analyzed in hypocotyls of wild-type (five plants, 225 cells) and ton1 (four plants, 306 cells) 6-d-old plants expressing the GFP-MBD marker, taking the hypocotyl axis as a reference. The entire length of wild-type and ton1 hypocotyls was scored. Distributions are strongly dissimilar (χ2 = 148, P < 0.001). NP, no preferential orientation.
