- Association Under low nitrogen, elevated CO2 shoot growth and elongation were associated with more cytokinin.
- Association Under moderate nitrogen, elevated CO2 shoot growth and elongation were associated with enhanced cytokinin and auxin.
- Intervention effect Lovastatin altered CO2-enhanced tall fescue growth under both nitrogen conditions.
- Intervention effect Auxin inhibitor altered CO2-enhanced tall fescue growth under both nitrogen conditions.
- Intervention effect FaCKX11 overexpression counteracted CO2-enhanced growth under low nitrogen.
- Intervention effect FaCKX11 overexpression reduced CO2-enhanced growth under moderate nitrogen.
- Intervention effect FaDAO overexpression counteracted CO2 growth enhancement under moderate nitrogen but not low nitrogen.
- Mechanism The authors interpret cytokinin as the primary mediator under low nitrogen.
- Mechanism The authors interpret cytokinin and auxin as mediators under moderate nitrogen.
