Other claims from this paper (8)
- Intervention effect Isobutyric acid rapidly and markedly decreased intracellular pH in barley leaf sections.
- Intervention effect Abscisic acid rapidly and markedly decreased intracellular pH in barley leaf sections.
- Intervention effect ABA increased proline to a level similar to IBA.
- Intervention effect Fusicoccin almost completely suppressed ABA-induced cell-sap acidification.
- Intervention effect Fusicoccin partially counteracted IBA acidification, especially during short treatment.
- Intervention effect Fusicoccin completely suppressed ABA-induced proline increase during short treatment.
- Intervention effect Fusicoccin inhibited IBA-induced proline accumulation only after long treatment.
- Mechanism The authors suggest intracellular pH changes mediate acid-induced proline changes.
