Rate of sucrose export from mature leaves of wild type (WT), αNtSUT1-35S17 (17), αNtSUT1-35S30 (30), and αNtSUT1-35S55* (55)
| Plant | Rate of Net Photosynthesis | Sucrose | K01 | Export Rate |
|---|---|---|---|---|
| μmol m−2 s−1 | mmol m−2 | μs−1 | μmol m−2 s−1 | |
| WT | 14.1 | 3.8 | 975 | 3.7 |
| 17 | 11.8 | 4.0 | 844 | 3.3 |
| 30 | 6.7 | 12.5 | 50 | 0.6 |
| 55* | 4.3 | 21.5 | 6 | 0.1 |
Export was calculated from the measured rate of net photosynthesis, the measured sucrose concentration in the leaf, and the transfer coefficient (K01). For details, see Methods.
