Other claims from this paper (11)
- Intervention effect OsABA8ox1 was induced by cold stress within 24 h.
- Intervention effect OsABA8ox2 and OsABA8ox3 were not induced by cold stress.
- Intervention effect OsABA8ox2 and OsABA8ox3 were ABA-inducible.
- Intervention effect OsABA8ox1 was not ABA-inducible.
- Intervention effect OsABA8ox1, OsABA8ox2 and OsABA8ox3 restored germination of an Arabidopsis cyp707a1/a2/a3 triple mutant to rates comparable to wild type.
- Mechanism OsABA8ox1, OsABA8ox2 and OsABA8ox3 act as ABA-catabolic genes in vivo.
- Intervention effect Overexpression of OsABA8ox1 increased seedling vigor at 15 °C.
- Mechanism Sustained low ABA levels lead to increased seedling vigor during cold stress.
- Intervention effect Excessively low endogenous ABA levels reduced drought and cold tolerance.
- Intervention effect Some transgenic rice lines expressing OsABA8ox1 at moderate levels did not show the harmful effects.
- Recommendation Adequate regulation of endogenous ABA levels is thought to be crucial for maintaining seedling vigor under cold stress.
