Other claims from this paper (8)
- Intervention effect Exogenous ureides applied to the soil inhibited N2 fixation by 85% to 90%.
- Intervention effect Water-deficit treatments inhibited N2 fixation by 85% to 90%.
- Intervention effect Mn fertilization increased the apparent catabolism of ureides in leaves in both cultivars.
- Association Ureides and total free amino acids in leaves and nodules increased during water deficits, coinciding with a decline in N2 fixation.
- Intervention effect N2 fixation recovered to 74% to 90% of control levels 2 d after rewatering.
- Observation Asparagine accounted for 82% of the increase in nodule amino acids relative to well-watered plants 2 d after rewatering.
- Mechanism Leaf ureides and nodule asparagine do not feedback-inhibit N2 fixation.
- Mechanism Nodule ureides, nodule aspartate and several leaf amino acids are candidate molecules for feedback inhibition of N2 fixation.
