7 Nitrogen fixation 'off switch' discovery could enable self-fertilizing crops¶
Aarhus University researchers identified a molecular switch in root proteins that controls nitrogen-fixing bacterial symbiosis. By modifying two amino acids in Symbiosis Determinant 1, they converted defensive receptors into symbiosis-initiating ones, with early success demonstrated in barley.
- Root protein receptor switch: Symbiosis Determinant 1 region
- Modifying 2 amino acids converts defensive to symbiosis receptor
- Early success in barley; potential for wheat, maize, and major crops
- Synthetic fertilizer ~2% of global energy consumption; generates significant CO₂

7 Grassland CO₂ absorption could decline 15% by 2050 due to plant diversity loss¶
A new model projects that global grassland CO₂ absorption could decline by approximately 15% by 2050 due to substantial loss of plant diversity, reducing carbon sequestration capacity.
- ~15% decline in grassland CO₂ absorption projected by 2050
- Driven by plant diversity loss reducing photosynthesis capacity
