Claim 1genetic associationsupports2026Source 1DOI PubMed

The rice mutant AZ1302 is defective in both aerenchyma formation and iron plaque formation, and its causal mutation maps to OsPSY2.

Claim 2mechanistic interpretationsupports2026Source 1DOI PubMed

The findings dissociate the roles of aerenchyma formation and iron plaque formation and support a model in which OsPSY2 integrates hormonal signaling to drive root plasticity.

Claim 3rescue effectsupports2026Source 1DOI PubMed

In psy2 mutants, exogenous abscisic acid restores iron plaque deposition.

Claim 4rescue effectsupports2026Source 1DOI PubMed

In psy2 mutants, exogenous strigolactones rescue aerenchyma formation.
