Other claims from this paper (14)
- Intervention effect SPHK mutants showed decreased sensitivity to ABA-promoted stomatal closure.
- Intervention effect pldα1 showed decreased sensitivity to ABA-promoted stomatal closure.
- Intervention effect Phyto-S1P promoted stomatal closure in sphk1-1.
- Intervention effect Phyto-S1P promoted stomatal closure in sphk2-1.
- Intervention effect Phyto-S1P did not promote stomatal closure in pldα1.
- Intervention effect PA promoted stomatal closure in sphk1-1.
- Intervention effect PA promoted stomatal closure in sphk2-1.
- Intervention effect PA promoted stomatal closure in pldα1.
- Intervention effect ABA activation of SPHK was reduced in pldα1.
- Intervention effect ABA-induced long-chain base phosphate accumulation decreased in pldα1.
- Intervention effect ABA-induced PA production decreased in SPHK mutants versus wild type.
- Mechanism The authors infer SPHK and phyto-S1P act upstream of PLDα1 and PA during ABA response.
- Mechanism The authors infer PA activates SPHK.
- Mechanism The authors infer PLDα1 activation requires SPHK activity.
