Summary of phenotypic analysis of female gametophytes and mature seed in gem2
| Developmental stage | No-O |
gem2 |
||
|---|---|---|---|---|
| Normal | Abnormal (%) | Normal | Abnormal (%) | |
| 1 Pre-fertilization | 55 | 3 (5) | 37 | 15 (29) |
| 2 2-4 cell embryo | 99 | 5 (5) | 71 | 36 (34) |
| 3 Globular embryo | 90 | 1 (1) | 74 | 40 (35) |
| 4 Mature seed | 1042 | 23 (2) | 878 | 497 (36) |
Data presented in this table are obtained using Nomarski optics 1, 2, 3 and from dissecting mature siliques 4 at comparable developmental stages. At mature seed stage aborted ovules could easily be distinguished from aborted seeds. The frequency of aborted seeds in wild type and gem2 was approximately 2%. It is possible that aborted seed could include gem2 homozygotes
