Leaf specific weight, dry matter percentage and chlorophyll content in 40-day old Wt and transplastomic tobacco plants.
| Genotype | Wt | Trx f+ | Trx m+ |
|---|---|---|---|
| Leaf specific weight (mg FW cm-2) | 21.4 ± 0.9 | 20.8 ± 1.6 | 21.0 ± 1.7 |
| % Dry matter | 10.3 ± 0.8 | 11.4 ± 1.1* | 10.2 ± 1.3 |
| Chl (μg cm-2) | 44.6 ± 1.4 | 41.1 ± 1.0** | 30.9 ± 1.3*** |
| Chl a (μg cm-2) | 31.6 ± 1.7 | 28.9 ± 1.0* | 23.4 ± 1.0*** |
| Chl b (μg cm-2) | 13.0 ± 0.6 | 12.2 ± 1.1 | 7.6 ± 0.3*** |
| Chl a/Chl b | 2.4 ± 0.2 | 2.4 ± 0.2 | 3.1 ± 0.1*** |
Chlorophyll content was measured in young well-expanded leaves of 40-day old Wt and transplastomic tobacco plants. Chlorophyll data are mean values ± SD from five independent measurements per plant and genotype. Leaf specific weight and dry matter data are mean values ± SD from eight independent measurements per plant and genotype. Each measurement was carried out using three 1-cm leaf disks. Wt, wild-type; Trx f+ and Trx m+, plants overexpressing Trx f or Trx m, respectively. Values significantly different from Wt values with *p > 0.05, **p > 0.01, and ***p > 0.001 (t-test).
