Title

Other claims from this paper (7)
- Observation MltPR10 genes are upregulated in nad1-1 nodules.
- Observation The nad1-1 pr10c pr10d triple mutant formed almost normal nodules relative to nad1-1.
- Observation The triple mutant restored nitrogenase activity relative to nad1-1.
- Observation MlPR10d showed ribonuclease activity against plant RNA.
- Observation The MlPR10d Y150F variant abolished RNase activity.
- Intervention effect The MlPR10d Y150F variant failed to restore necrosis in triple mutant plants.
- Mechanism The authors infer that PR10 RNase activity directly influences nodule cell fate and may execute RNA degradation in immune associated cell death.
