- Intervention effect Dark submergence increased endogenous IAA accumulation in rice.
- Mechanism High endogenous IAA under dark submergence stimulated rice coleoptile elongation.
- Mechanism High endogenous IAA under dark submergence limited rice root growth.
- Mechanism High endogenous IAA under dark submergence limited rice primary leaf growth.
- Intervention effect Light reduced rice IAA levels.
- Intervention effect Oxygen promoted rice seedling establishment and enhanced anaerobic germination tolerance.
- Intervention effect Light promoted rice seedling establishment and enhanced anaerobic germination tolerance.
- Intervention effect Submergence negatively regulated rice miR167 expression.
- Mechanism The miR167-ARF-GH3 pathway modulated rice free IAA accumulation.
- Mechanism Rice OsGH3-8 encodes an IAA-amido synthetase that prevents free IAA accumulation.
- Intervention effect Reduced miR167 levels increased rice auxin metabolism.
- Intervention effect Reduced miR167 levels reduced rice free IAA.
- Intervention effect Reduced miR167 levels enhanced rice anaerobic germination tolerance.
- Intervention effect OsGH3-8 overexpression increased rice auxin metabolism.
- Intervention effect OsGH3-8 overexpression reduced rice free IAA.
- Intervention effect OsGH3-8 overexpression enhanced rice anaerobic germination tolerance.
- Mechanism Excessive IAA may cause poor rice germination and seedling growth under submergence.
- Mechanism Excessive IAA driven inhibition may cause rice intolerance to submergence.
- Mechanism A threshold auxin level may be essential for rice anaerobic germination tolerance.
