cna Mutations Enhance clv Shoot Meristem Sizes
| Genotype | Shoot Meristem Size (μm)a | Age (d)b | nc |
|---|---|---|---|
| clv2-1 | 58 ± 2.5d | 13 | 12 |
| clv2-1 cna-1/cna-1 | 109 ± 16.6 | 13 | 12 |
| clv3-2 | 163 ± 11.1e | 13 | 18 |
| clv3-2 cna-1/+ | 196 ± 9.1 | 13 | 18 |
| clv3-2 cna-1/cna-1 | 276 ± 9.3 | 13 | 32 |
| clv3-2 cna-2/cna-2 | 223 ± 12.1 | 13 | 16 |
| clv1-7 | 71 ± 2.8f | 15 | 8 |
| clv1-7 cna-1/cna-1 | 95 ± 2.1 | 15 | 8 |
Values represent the mean shoot apical meristem diameter ± standard error (see Methods).
Age indicates the days after germination plants were collected.
n indicates the number of measurements used to determine size.
The mean meristem diameter for clv2-1 is significantly different from that of clv2-1 cna-1 plants (t test, P < 0.01).
The mean meristem diameter for clv3-2 is significantly different from that of clv3-2 cna-1/CNA plants (P = 0.03), clv3-2 cna-1 plants (t test, P < 0.01), and clv3-2 cna-2 plants (P < 0.01).
The mean meristem diameter for clv1-7 is significantly different from that of clv1-7 cna-1 plants (t test, P < 0.01).
