Other claims from this paper (16)
- Observation T22 colonised the roots of garden pea cultivars under soil alkalinity in a host-specific manner.
- Intervention effect T22 improved growth parameters of alkaline-exposed Sugar Snap.
- Intervention effect T22 increased tissue mineral content in alkaline-exposed Sugar Snap, particularly Fe and Mn.
- Intervention effect T22 enhanced rhizosphere siderophore levels in alkaline-exposed Sugar Snap.
- Mechanism The beneficial effect of T22 on alkaline stress mitigation reflects a whole-plant association rather than localised root-specific effects.
- Intervention effect Under alkaline conditions, 575 genes were upregulated in roots inoculated with T22.
- Intervention effect Under alkaline conditions, 818 genes were downregulated in roots inoculated with T22.
- Observation Upregulated genes under T22 were mostly involved in the flavonoid biosynthetic pathway.
- Intervention effect A flavonoid precursor restored plant health without T22.
- Intervention effect T22 restored the abundance of rhizobia, particularly R. leguminosarum and R. indicum.
- Intervention effect T22 induced NifA, NifD and NifH expression in nodules.
- Intervention effect Exogenous Fe lowered rhizosphere siderophore, root flavonoid and PsCoA expression relative to T22.
- Intervention effect Exogenous Fe lowered the relative abundance of TaAOX1 and R. leguminosarum relative to T22.
- Mechanism Exogenous Fe removes the need for microbiome-driven mineral mobilisation.
- Mechanism T22-mediated alkaline stress mitigation depends on flavonoid-driven symbiosis and R. leguminosarum abundance.
- Intervention effect T22 had a positive interaction with R. leguminosarum growth in alkaline media.
