| CUL3A/CUL3A cul3b/cul3b | 99.48% | 0.52% | 764 |
| cul3a/cul3a CUL3B/CUL3B | 99.84% | 0.16% | 637 |

a
Developing seeds from siliques obtained from the self-pollination of plants with the genotypes described were used for the stereoscopic and DIC analyses.
b
Segregation frequencies of green developing ovules that contain normally developing embryos, which eventually turn into mature brown seeds after the normal maturation/desiccation processes (see Figure 2 and Results for details).
c
Segregation frequencies of defective pale green/yellowish developing ovules that contain embryos arrested at globular/early heart-like stages. These ovules turn into aborted red shrunken seeds (see Figure 2 and text for details).
