2024年4月13日 · Here, we report that a plant NLR Sw-5b mimics the behavior of the ABA receptor and directly employs the ABA central regulator PP2C-SnRK2 complex to activate an …
Type 2C protein phosphatases directly regulate abscisic acid ... - PNAS
2009年10月13日 · Abscisic acid (ABA) signaling is important for stress responses and developmental processes in plants. A subgroup of protein phosphatase 2C (group A PP2C) or …
The PP2C-SnRK2 complex: The central regulator of an abscisic …
When the soluble ABA receptor recognizes the ABA molecule, it binds PP2C and inhibits its phosphatase activity. Then SnRK2 is activated and phosphorylates its targets, and the ABA …
ABA inducible rice protein phosphatase 2C confers ABA ... - PubMed
2015年4月17日 · We have identified a group A PP2C from rice (OsPP108), which is highly inducible under ABA, salt and drought stresses and localized predominantly in the nucleus.
Initiation and amplification of SnRK2 activation in abscisic acid ...
2021年4月28日 · In the presence of ABA, ABA receptor PYR/PYL/RCARs (PYL) complex binds to and inhibits PP2C and SnRK2 is released from PP2C-mediated inhibition. SnRK2 can then be …
Transcriptional Regulation of Protein Phosphatase 2C Genes to …
The induction of PP2C gene expression may be an ABA desensitization mechanism modulating ABA signaling and maintaining plant homeostasis. Therefore, ABA upregulates genes …
