Parameters of apical cells in four different g-related treatments
| Treatment | Cell Widtha | Cell Lengtha | Distance Tip To Nucleus | Percentb |
|---|---|---|---|---|
| μm | ||||
| Upright | 12.9 ± 1.3 | 177.2 ± 37.3 | 91.6 ± 14.1 | 51.7 |
| Microgravity | 11.7 ± 1.1c | 179.6 ± 44.0 | 83.2 ± 11.3c | 46.3 |
| Clino-rotated | 16.3 ± 2.0c | 206.8 ± 49.2c | 109.7 ± 14.7c | 53.0 |
| Inverted | 15.0 ± 1.3c | 183.7 ± 32.3 | 99.5 ± 9.0c | 54.2 |
Moss cells were grown in an upright stationary position, or rotated on a clinostat, or were grown in microgravity for 14 d. Other cells were inverted for 6 h. The sample included between 34 and 145 cells in each treatment.
a
Mean ± sd.
b
Third data column divided by second column expressed as a percentage.
c
Different statistically from upright cells (P ≥ 0.95).
