| Research Abstract |
We pursued to identify the ABA receptors PYR/PYL/RCAR interacting proteins, post-translational modification sites in PYR/PYL/RCAR and natural ligands bind to PYR/PYL/RCAR. PYR/PYL/RCAR strongly interacts with cluster A PP2Cs and seems to be regulated by ubiqutination. The candidate natural ligands bind to PYR/PYL/RCAR has ABA like function but not ABA. The cluster A PP2Cs interact with different known ABA signaling components among them, suggested that plant conveniently selected the interactors to transduce ABA signaling.
