Jun 12, 2018 · Abscisic acid (ABA) is an important phytohormone controlling responses to abiotic stresses and is sensed by proteins from the PYR/PYL/RCAR family. To explore the genetic contribution of PYLs toward ABA-dependent and ABA-independent processes, we generated and characterized high-order Arabidopsis mut …

Jun 12, 2018 · Abscisic acid (ABA) is an important phytohormone controlling responses to abiotic stresses and is sensed by proteins from the PYR/PYL/RCAR family. To explore the genetic contribution of PYLs toward ABA-dependent and ABA-independent processes, we generated and characterized high-order Arabidopsis mutants with mutations in the PYL family.

Nov 5, 2009 · PYL-PYR proteins were recently described as receptors for the plant hormone abscisic acid (ABA) and as inhibitors of the phosphatases ABI1 and ABI2 in the presence of ABA.

Feb 24, 2025 · Recent evidence indicates that ABA perception emerged from a latent signaling pathway involving a constitutively PP2C-inhibiting PYL homolog. Consequently, ancestral ABA receptors exerted high background signaling, limiting …

Jan 1, 2019 · The PYRABACTIN RESISTANCE1 (PYR1)/PYR1-LIKE (PYL)/REGULATORY COMPONENTS OF ABA RECEPTORS (RCAR) are currently recognized as the canonical ABA receptors based on structural, biochemical and genetic evidences obtained independently by several groups (Gonzalez-Guzman et al., 2012, Ma et al., 2009, Melcher et al., 2009, …

Jun 30, 2016 · We report a link between ABA and JA signaling through a direct interaction of the ABA receptor PYL6 (RCAR9) with the basic helix-loop-helix transcription factor MYC2. PYL6 and MYC2 interact in...

In this study, we demonstrate that ABA restrains root gravitropism and lateral root formation under salt or osmotic stress via a novel branch of the ABA signaling pathway, which involves a complex of the PYLs ABA receptor and PP2A.

Sep 30, 2020 · Abscisic acid (ABA), a key phytohormone that controls plant growth and stress responses, is sensed by the pyrabactin resistance 1(PYR1)/PYR1-like (PYL)/regulatory components of the ABA receptor (RCAR) family of proteins.

As abscisic acid (ABA) receptor, the pyrabactin resistance 1-like (PYR/PYL) protein (named PYL for simplicity) plays an important part to unveil the signal transduction of ABA and its regulatory mechanisms.

We found that PYL8 mediates a synergistic action of ABA and auxin in promoting the growth recovery of post-emergence lateral roots. In addition, we found evidence for the function of the core ABA signaling components, PYR1/PYL/RCARs, PP2Cs, and SnRK2s, in the inhibition of lateral root growth.
