Dry weight accumulation and leaf area of transgenic tomato plants expressing AtIPT under source leaf-specific promoter FBPase or root cap-specific promoter AtMDK.
| Shoot dry weight (g) | Root dry weight (g) | Root:shoot ratio | Average leaf size (cm2) | |
|---|---|---|---|---|
| M82 | 21.6 ± 1.5 a | 15.5 ± 0.7 a | 0.73 ± 0.06 | 117 ± 16 |
| FBPase:IPT | 13.4 ± 2.4 b | 10.2 ± 1.3 b | 0.79 ± 0.05 | 93 ± 11 |
| M82 | 19.3 ± 2.4 a | 15.8 ± 1.4 a | 0.86 ± 0.1 a | 125 ± 19 a |
| AtMDK:IPT | 1.8 ± 0.4 b | 4.5 ± 0.8 b | 3.04 ± 0.4 b | 24 ± 15 b |
Data represent means (±SE) of six replicates of two independent experiments comparing each transgenic line with the control variety M82.
Different lowercase letters indicate significant differences between the control and the respective transgenic plants by Student’s t-test, p < 0.05.
