Abstract

Background : Sphingosine kinase (SPHK) and phospholipaseD(PLD) produce different lipid mediators involved in abscisic acid (ABA) response.

Results: Ablation of SPHKs and PLD α1 attenuates ABA-induced production of LCBPs and PA. Phyto-S1P closes stomata in sphk 1 , sphk 2, but not in pld α1 , whereas PA closes stomata in all mutants.

Conclusion : SPHK acts upstream of PLDα1, whereas PLDα1 promotes SPHK.

Significance : The roles of lipid messengers in the ABA signaling pathway are clarified.
