Other claims from this paper (11)
- Observation At low phosphorus, VAM roots had 13% more shoot dry weight.
- Observation At low phosphorus, VAM roots had 30% greater protein concentration.
- Observation At low phosphorus, VAM and non-VAM root growth did not differ significantly.
- Observation At higher phosphorus, mycorrhizal roots weighed 10% less than non-VAM roots.
- Observation At higher phosphorus, host growth and root phosphorus concentration did not change concurrently.
- Association Mycorrhizal colonization declined as soil phosphorus increased.
- Intervention effect Formononetin enhanced root colonization by G. intraradices and partly countered high phosphorus inhibition.
- Association Root ACP and ALP activity were associated with fungal colonization.
- Association ACP activity responded 38% more to soil phosphorus than ALP activity.
- Mechanism Authors suggest ACP contributed to soil phosphorus uptake.
- Mechanism Authors suggest ALP may be linked to phosphate assimilation or transport.
