Other claims from this paper (11)
- Intervention effect Ammonium fertilization at 400 ppm CO2 strongly reduced stomatal conductance.
- Mechanism Reduced stomatal conductance negatively affected photosynthetic rates.
- Observation Ammonium fertilization at 400 ppm CO2 was associated with higher PIP1.1 and PIP 2.3 expression.
- Mechanism Higher PIP expression might compensate for restricted CO2 delivery to chloroplasts.
- Mechanism Stomatal limitation might reduce ammonium transport toward leaves.
- Observation Ammonium-fertilized plants at elevated CO2 showed no stress symptoms.
- Intervention effect At elevated CO2, ammonium-fertilized plants showed no difference in stomatal opening.
- Intervention effect At elevated CO2, ammonium-fertilized plants showed no difference in water use efficiency.
- Intervention effect At 700 ppm CO2, aquaporin gene expression was similar under ammonium, nitrate, and ammonium nitrate fertilization.
- Intervention effect Ammonium and ammonium nitrate fertilization increased photosynthetic rates under elevated CO2.
- Mechanism Increased photosynthesis under elevated CO2 translated into higher leaf protein content.
