Target Background
Function
PYL9 is a receptor for abscisic acid (ABA), crucial for ABA-mediated responses such as stomatal closure and germination inhibition. It inhibits group A protein phosphatase 2C (PP2C) activity, both in an ABA-dependent and -independent manner, with greater efficiency in the presence of ABA. PYL9 enhances ABA sensitivity and is activated exclusively by (+)-ABA, not (-)-ABA.
Gene References Into Functions
PYL9 Function and Related Research:
- Regulation of ABA Signaling: AtRAE1, implicated in ABA signaling, potentially regulates the degradation of the abscisic acid receptor RCAR1. PMID: 29044697
- Crosstalk with Auxin Pathways: PYL9 interacts with MYB transcription factors, modulating their transcriptional activity, representing a convergence point between ABA and auxin signaling pathways. PMID: 27256015
- Role in Leaf Senescence and Drought Resistance: PYL9 plays a significant role in ABA-induced leaf senescence and contributes to drought stress resistance. PMID: 26831097
- ABA Binding Affinity: Structural analysis reveals that specific amino acid residues (Ile110, Val162, Leu165, and Pro64) enhance ABA binding affinity by influencing the ABA carboxyl group's interaction with Asn169. PMID: 24645846
- Stomatal Regulation: The RCAR receptor contributes to stomatal regulation in response to ozone, reduced air humidity, and darkness. PMID: 23703845
