Other claims from this paper (12)
- Observation Shoot phenotyping of Brachypodium revealed rapid responses to nitrogen availability.
- Intervention effect Under N limitation, inoculated plants accumulated significantly more biomass and total N than uninoculated controls.
- Intervention effect Under N limitation, biomass and total N of inoculated plants reached levels comparable to high N plants.
- Intervention effect No inoculation effect was observed under high N.
- Observation Biomass increases were accompanied by only modest changes in tissue N concentration.
- Observation The authors interpret this as enhanced whole-plant N-use efficiency rather than disproportionate N enrichment.
- Association Proteomics identified N availability as the primary determinant of proteome structure.
- Intervention effect Bacterial inoculation under low N conditionally modulated selected proteome modules towards High N states.
- Association Lipidomic profiles were largely driven by N availability.
- Intervention effect Inoculation had only transient effects on lipidomic profiles at early stages.
- Observation Delta-15N analyses did not support substantial in planta N fixation by P. koreensis despite N fixation-associated genes in the bacterium.
- Mechanism The authors propose that inoculation enhances growth under N limitation by modulating plant-encoded N acquisition and metabolic organization.
