文摘
- •
ABA and SA inhibit basal PI-PLC in Arabidopsis suspension cells.
- •
ABA, contrary to SA, does not lead to increase in phosphoinositides.
- •
We detect a major overlap between the transcriptomic responses to ABA and to SA.
- •
The overlap concerns genes that respond similarly to inhibitors of the PI-PLC pathway.
- •
Our analysis suggests a central role of this enzyme in hormonal cross-talk.
