Other claims from this paper (8)
- Observation Under high-P conditions the two P-efficient soybean genotypes appeared more Al tolerant than the two P-inefficient genotypes.
- Intervention effect Aluminum toxicity induced citrate exudation from soybean roots.
- Intervention effect Phosphorus deficiency triggered oxalate exudation from soybean roots.
- Intervention effect Malate release from soybean roots was induced by both Al toxicity and P deficiency.
- Observation In the divided root chamber experiment the two P-efficient soybean genotypes were more Al tolerant than the P-inefficient lines during the early stages.
- Observation In the divided chamber experiments the exudation patterns of the same three organic acids differed from those in the homogeneous solution system.
- Observation The two P-efficient soybean genotypes secreted more malate from the taproot tip.
- Mechanism The authors suggest improved P nutrition may enhance organic acid exudation in the root regions facing the greatest Al toxicity, thus enhancing Al tolerance.
