- Intervention effect All tested mineral deficiencies lowered barley RuDPCase concentration.
- Intervention effect All deficient barley plants had higher soluble protein than controls.
- Intervention effect Adding 18 μM Mn²⁺ increased RuDPCase activity as much as 133% above normal.
- Intervention effect RuDPCase specific activity in Mg-deficient barley was 60% of control.
- Intervention effect RuDPCase specific activity in Mn-deficient barley was 118% of control.
