Table 1.
Cell walls apparent elastic modulus measured in cells of the elongation zone of roots of Col-0, ttl1, prc1-1 and ttl1prc1-1 grown in control conditions.
| Control | Y (kPa) | N | Error |
|---|---|---|---|
| Col-0 | 88.12 ± 2.79 a | 201 | 0.19 |
| ttl1 | 16.08 ± 6.87 b | 1184 | 0.19 |
| prc1-1 | 18.08 ± 8.04 c | 2231 | 0.17 |
| ttl1 prc1-1 | 27.06 ± 8.5 d | 1052 | 0.26 |
Values are means ± SD; 200-2231 force curves were obtained from the central part of elongation cells of 3 roots for each growing condition. Seedlings were attached to petri dishes with silicone and covered with 1× phosphate-buffered saline (PBS) solution. Normalized Young’s modulus histograms were obtained from all experimental conditions. Each histogram was fitted with a Gaussian curve. Statistical significance is as follows: p < 0.05 (by Student’s t-test) for a vs. b and p < 9.8971 × 10−306 (by Student’s t-test) for c vs. d.
