The EAR motif-containing adaptor protein ECAP enhances the assembly of PYR1-ABI1 complex to promote ABA signaling in Arabidopsis
{{output}}
The phytohormone abscisic acid (ABA) plays a pivotal role in plant growth, development, and stress responses. In the ABA signaling pathway, ABA-bound PYR1/PYL receptors form complexes with PP2Cs co-receptors, thereby releasing SnRK2 kinases from repression. Ho... ...
