Table 1.
Two-way ANOVAs to test the effects of the 5-enolpyruvoylshikimate-3-phosphate synthase (epsps) transgene (fixed effect), four weedy rice (Oryza sativa f. spontanea) biotypes (random effect), and their interaction on EPSPS content (F2 generation), tryptophan concentration (F3), photosynthetic rate (F3), and seed germination (F3)
| Trait | Transgene (T) | Weedy rice (W) | T × W | ||||||
|---|---|---|---|---|---|---|---|---|---|
| df | F | P | df | F | P | df | F | P | |
| EPSPS content | 1 | 8.289 | 0.064 | 3 | 1.635 | 0.345 | 3 | 3.351 | 0.045 |
| Tryptophan concentration | 1 | 14.996 | 0.030 | 3 | 8.604 | 0.055 | 3 | 5.092 | 0.012 |
| Photosynthetic rate | 1 | 118.369 | 0.002 | 3 | 14.536 | 0.027 | 3 | 0.395 | 0.758 |
| Seed germination (%) | 1 | 25.773 | 0.015 | 3 | 5.657 | 0.094 | 3 | 3.317 | 0.032 |
The transgene (T) had two levels (genetically engineered (GE) or non-GE) and weedy rice biotype (W) had four levels.
