The Identification of FERONIA‑interacting proteins in Arabidopsis thaliana via mass spectrometry

ABSTRACT: FERONIA (FER) is a plasma membrane-localized receptor-like kinase (RLK) that belongs to the Catharantus roseus RLK1-like (CrRLK1L) subfamily. FER serves as a potential cell wall sensor that regulates multiple phytohormones, including ABA, JA, SA, BR, auxin, and ethyl, but the underlying regulatory mechanisms are still largely unknown. To further understand how FER regulates downstream signaling pathway, we performed FER-interacting proteins via immunoprecipitation-mass spectrometry (IP-MS) assay generated from FER-GFP transgenic plants.

FERONIA-mediated CC1 phosphorylation dynamically regulates cortical microtubule behavior and salt stress responses in Arabidopsis

Project description:Cell wall remodeling is important for plants to adapt to environmental stress, and therefore needs to be efficiently modulated during stress conditions. Under salt stress, cortical microtubules undergo a depolymerization-reassembly process to promote the biosynthesis of stress-adaptive cellulose, but the regulatory mechanisms underlying this process are still largely unknown. In this study, we reveal that FERONIA, a potential cell wall sensor, interacts with CC1 and its closest homolog, CC2; two proteins that are required for cortical microtubule reassembly under salt stress. Biochemical data indicate that FER phosphorylates CC1 on multiple residues in the second and third hydrophobic microtubule-binding regions in vitro and in vivo, and that these phosphorylations impact the ability of CC1 to engage with microtubules. Furthermore, FER kinase activity and the CC1 phosphorylation level were temporally coordinated upon exposure to salt stress, which coincided with dynamic microtubule reorganization. Both fer-4 and cc1 cc2 mutants displayed similar salt-sensitive phenotypes, which were related to compromised microtubule reassembly, corroborating that FER and CC1/CC2 function in the same pathway to regulate microtubule organization. Taken together, our study outlines an important intracellular mechanism that maintains microtubule dynamics during salt exposure in plant cells.

The interaction proteins of FER were identified by mass spectrometry

Project description:Catharanthus roseus Receptor-Like Kinase 1-like (CrRLK1L) family proteins are considered as potential cell wall sensors in plants. CrRLK1L subfamily proteins harbor two extracellular malectin-like domains that may bind to cell wall polymers, and an intracellular kinase domain that transmits signals via the phosphorylation of intracellular substrates. In Arabidopsis, there are 17 CrRLK1L family members, among which FER is the most widely studied. A growing body of evidence support that FER not only regulates plant growth and development, such as root hair development, pavement cell morphogenesis, flowering, and fertilization, but also controls plant responses to biotic and abiotic stresses. To decipher molecular mechanisms underlying the FER-mediated regulation of plant growth and development, we performed an immunoprecipitation-mass spectrometry (IP-MS) assay using FER-GFP transgenic plants to search for FER-interacting proteins.

FERONIA controls ABA-mediated seed germination via the regulation of the kinase activity of CARK1

Project description:Seed germination is the initial step of the whole life cycle for an individual plant, and thus it needs to be tightly controlled to avoid the growth of plants under unfavorable conditions, such as high salinity and drought stress. It has been well known that ABA signaling pathway plays a key role in the regulation of seed germination. In this study, we found that FER, a receptor-like kinase that belongs to CrRLK1L subfamily, regulates seed germination under ABA or stress conditions via the modulation of ABI5 protein stability. Biochemical data indicate that FER interacts with and phosphorylates CARK1 protein, a receptor-like cytoplasmic kinase (RLCK) that is classified into the RLCK VIII subfamily. FER phosphorylates the Ser233 and Thr234 residues of CARK1, and these two residues are located in the activation loop and are required for the activation of CARK1. The CARK1 protein with the substitutions of these two amino acids to Ala exhibits reduced kinase activity and is not able to rescue the faster seed germination phenotype of cark1 mutant under ABA conditions. In both fer-4 and cark1 mutant, the ABA-triggered activation of SnRK2.6 and ABI5 protein accumulation were attenuated compared with the wild-type. Taken together, our study not only reveals a RLCK protein that functions directly downstream of FER to transduce external signals, but also provides a novel mechanistic insight into the understanding of seed germination regulation via ABA-mediated signaling pathways.

Transcriptomic profile of FERONIA mutant treated with Aradopside

Project description:FERONIA (FER) receptor kinase has a versatile role in plant growth and development, biotic and abiotic stress responses, and reproduction. To gain new insights into the molecular interplay of these processes and to identify new functions of FER, we carried out quantitative transcriptome, proteome, and phosphoproteome profiling of wild type (WT) and a loss-of-function fer mutant in Arabidopsis plants. Gene Ontology terms for hormone signaling, abiotic stress, and biotic stress were significantly enriched among mis-expressed transcripts, proteins, and/or mis-phosphorylated proteins, in agreement with FER’s known roles in these processes. Analysis of multi-omics data and subsequent experimental evidence identified previously unknown functions of FER in ER (Endoplasmic Reticulum) body formation, glucosinolate biosynthesis. FER functions through transcription factor NAI1 to mediate ER body. FER also negatively regulates indole glucosinolates biosynthesis, partially through NAI1. Furthermore, we found that a group of abscisic acid (ABA)-induced transcription factors are hypo-phosphorylated in the fer mutant and demonstrated that FER acts through ABI5 to negatively regulate the ABA response during germination. Our integrated-omics study therefore reveals novel functions of FER and provides new insights into the underlying mechanisms of FER function.

The FERONIA receptor kinase is required for high humidity responses in Arabidopsis

Project description:High humidity greatly influences plant growth and development by triggering adaptive physiological responses such as leaf hyponasty. Recent studies identified CNGC2/4-mediated Ca2+ influx and CAMTA2/3-mediated transcription as essential for this process, but the upstream regulators that control these pathways remain unknown. Here, we show that the receptor-like kinase FERONIA (FER) is required for Arabidopsis adaptation to high humidity. Transcriptomic profiling revealed rapid induction of CNGC2, CAMTA targets, and pectin remodeling genes in wild-type plants but not in fer-4 loss of function mutants. A targeted mutant screen confirmed that FER and its co-receptor LORELEI-LIKE GPI-ANCHORED PROTEIN1 (LLG1) are essential for humidity-induced hyponasty. Whole-plant Ca²⁺ imaging demonstrated that high humidity triggers conserved cytosolic Ca²⁺ elevations across species, including petiole-localized Ca²⁺ waves in Arabidopsis that precede hyponastic movement by ~2 h. These signals were significantly attenuated in fer-4, providing a mechanistic explanation for its transcriptional and physiological defects. Together, our findings identify FERONIA as a key upstream component of a sensing mechanism linking extracellular high humidity to Ca²⁺ signaling, cell wall remodeling, and adaptive leaf movement.

An Omics approach on Marchantia polymorpha single FERONIA and MARIS homologs confirms links between cell wall integrity and abscisic acid

Project description:Plant cells are surrounded by an extracellular cell wall that shields them from their abiotic and biotic environment. To coordinate their growth with their cell wall status, they have developed cell wall integrity mechanisms at the center of which lies the transmembrane Malectin-like receptor kinase FERONIA (FER). FER controls a myriad of plant developmental processes including sexual reproduction, cell growth and morphogenesis, often intersecting with phytohormones-dependent pathways such as abscisic acid (ABA) or plant immunity. Interestingly, FER and its downstream receptor-like cytoplasmic kinase MARIS (MRI) were shown to cooperate similarly in the control of root hair and rhizoid integrity for the vascular model Arabidopsis and the early diverging bryophyte model Marchantia polymorpha, respectively. Here, we carried out comparative transcriptomics and proteomics approach on Mpfer-1 and Mpmri-1 knock-down mutant plants and the wild-type strains Tak-1 and Tak-2. Our -omics analyses revealed that globally, MpFER and MpMRI largely cooperate to negatively regulate transcriptional and translational networks in particular those related to plant defense and ABA responses. Moreover, Mpfer-1 plants were found to be hypersensitive to ABA-dependent growth inhibition indicating that FER’s function of negatively regulating ABA-related growth responses is conserved between bryophytes and vascular plants.

FERONIA regulates plant growth and survival under salt stress by modulating the dark reversion of phyB via a signature of phosphorylation

Project description:Here we report that FERONIA (FER) integrates phyB-mediated light signaling pathway to control salt stress response. Mutation in phytochrome B (phyB) largely suppresses the dwarfism and leaf bleaching phenotype of fer-4 mutant under salt stress. FER interacts with and phosphorylates the N-terminal domain of phyB. Mutation in fer-4 or disruption of the FER-mediated phosphorylation sites of phyB at Ser106 and Ser227 leads to a retention of phyB in the photobodies under dark conditions, suggesting that FER-mediated phosphorylation accelerates the dark reversion of phyB. Interestingly, salt stress slows down the dark reversion of phyB via the inhibition of the kinase activity of FER, and mutation of phyB or overexpression of PIF5 attenuates the salt-induced growth inhibition. Together, our study indicates that the plasma membrane-localized FER determines the dark reversion rate of phyB in the nucleus via a signature of phosphorylation and thus coordinates the extracellular stress signals and nuclear outputs to dynamically control plant growth and survival under stress conditions.
