Table 1.
Respiratory parameters in NDB1-suppressing and WT Arabidopsis plants grown on NH4+ and NO3− (control) as the only source of nitrogen. Values are shown for total respiration (Vt), cytochrome pathway capacity (Vcyt), and alternative pathway capacity (Valt) in dark-adapted leaves. Results with different letters are statistically different (p < 0.05) by ANOVA.
| WT NO3− | WT NH4+ | NDB1 NO3− | NDB1 NH4+ | |

| Oxygen consumption (nmol O2 min−1 g−1 FW) | ||||
| Total respiration (Vt) | 40.54 a ± 9.93 | 93.16 c ± 3.67 | 41.38 a ± 5.99 | 72.92 b ± 2.96 |
| +SHAM (Vcyt) | 37.31 a ± 7.65 | 66.09 b ± 6.39 | 36.46 a ± 10.84 | 55.45 ab ± 4.62 |
| +KCN (Valt) | 5.94 a ± 3.11 | 38.98 b ± 10.58 | 5.82 a ± 1.38 | 46.47 b ± 2.74 |
