Quantitative Effects of ARF10, ARF16, and miR160 on Root Growth
| Seedling Type | Primary Root Length (mm) | Lateral Root Number |
|---|---|---|
| Wild type (Col-0) | 39.86 ± 3.50 | 5.33 ± 1.01 |
| Pro35S:MIR160c | 23.18 ± 5.44a | 8.70 ± 1.15a |
| arf10-2 | 39.45 ± 2.70 | 5.10 ± 0.98 |
| arf16-2 | 40.11 ± 2.52 | 5.25 ± 0.97 |
| arf10-2 arf16-2 | 32.15 ± 4.90a | 7.20 ± 1.30a |
| ProARF16:ARF16 | 40.15 ± 4.25 | 5.38 ± 1.23 |
| ProARF16:mARF16 | 42.55 ± 4.50b | 3.00 ± 1.26a |
The seedlings were grown vertically for 9 d under continuous light. For each line, ∼30 seedlings were scored.
a
Significantly different compared with the wild type (P < 0.001) by Student's t test.
b
Significantly different compared with the wild type (0.01 < P < 0.02) by Student's t test.
