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

ABSTRACT: 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.

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.

The LRX-RALF-FER cell wall integrity sensing module controls plant growth and salt stress responses by modulating multiple plant hormones

Project description:Plants have evolved cell wall integrity signaling pathways to maintain cell wall homeostasis during rapid growth and in response to environmental stress. The cell wall leucine-rich repeat extensins LRX3/4/5, the RAPID ALKALINIZATION FACTOR (RALF) peptides RALF22/23, and FERONIA (FER) function as a module to regulate plant growth and salt stress responses via the sense of cell wall integrity. However, the intracellular signaling pathways that mediate the effects of the LRX3/4/5-RALF22/23-FER module are still largely unknown. Here, we report that jasmonic acid (JA), salicylic acid (SA), and abscisic acid (ABA) accumulate constitutively in lrx345 and fer mutants. Blocking JA pathway rescues the retarded growth phenotype of the lrx345 and fer-4 mutants, while disruption of ABA biosynthesis suppresses the salt-hypersensitivity of these mutants. Many salt stress-responsive genes display abnormal expression patterns in the lrx345 and fer-4 mutants, as well as in wild type plants treated with epigallocatechin gallate (EGCG), an inhibitor of pectin methylesterases, suggesting that the cell wall integrity is a critical factor that determines the expression of stress-responsive genes. Production of reactive oxygen species (ROS) is constitutively increased in the lrx345 and fer-4 mutants, and inhibition of ROS accumulation suppresses the salt-hypersensitivity of these mutants. Together, our results suggest that the LRX3/4/5-RALF22/23-FER module controls plant growth and salt stress responses by regulating hormonal homeostasis and ROS accumulation.

A regulatory module controls plant growth and stress response by modulating hormone level

Project description:Perception and relay of cell wall signals is critical for plants to regulate growth and stress responses, but the mechanism underlying this biological process remains largely unknown. Here we report that RAPID ALKALINIZATION FACTOR (RALFs) peptides, Leucine-rich repeat extensins (LRXs) and FERONIA (FER) are physically associated in extracellular region. lrx345, fer-4, and transgenic plants overexpressing RALF22 or RALF23 all showed retarded growth, increased sensitivity to salt stress, and constitutively increased levels of ABA, JA, and SA. Salt treatment or chemical disruption of cell wall promotes the release of mature RALF peptides, which negatively regulate the function of FER by inducing its internalization. JA mutants coi1 and aos restore the retarded growth, and mutation of ABA2 suppresses the salt-sensitive phenotype of lrx345. Together, we propose that LRXs, RALFs, and FER function as a module to sense and transduce cell wall signals, thereby regulating growth and stress responses via hormones-mediated 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.

RNA-seq to identity genes expressed in dissected inflorescence meristems of Col-0 Arabidopsis thaliana plants.

Project description:The shoot apical meristem of higher plants continuously generates new tissues and organs through complex changes in growth rates and directions of its individual cells. Cell growth, driven by turgor pressure, largely depends on the cell walls, which allow cell expansion through synthesis and structural changes. A previous study revealed a major contribution of wall isotropy in organ emergence, through the disorganization of cortical microtubules. We show here that this disorganization is coupled with the transcriptional control of genes involved in wall remodelling. Some of these genes are induced when microtubules are disorganized and cells shift to isotropic growth. Mechanical modelling shows that this coupling has the potential to compensate for reduced cell expansion rates induced by the shift to isotropic growth. Reciprocally, cell wall loosening induced by different treatments or altered cell wall composition promotes a disruption of microtubule alignment. Our data thus indicate the existence of a regulatory module activated during organ outgrowth, linking microtubule arrangements to cell wall remodelling.

Identification of potential interactors of COMPANION OF CELLULOSE SYNTHASE (CC) 1

Project description:Salt stress is one of the most detrimental abiotic stresses for plants. The plant cell wall, which encases plant cells and functions as a cellular exoskeleton, is an important structure to cope with such stresses. One of the main components of the cell wall is cellulose, which is synthesized by cellulose synthase (CESA) complexes (CSC) at the plasma membrane by moving along underlying cortical microtubules. COMPANION OF CELLULOSE SYNTHASE (CC) 1 and 2 have been identified to be components of the CSCs, and function in maintaining cellulose synthesis under salt stress by supporting microtubules and CESA behaviors. However, the exact regulatory mechanisms of the CC1 and CC2 proteins remain largely unknown. In this project, we did an immunoprecipitation-mass spectrometry (IP-MS) analysis to identify potential interactors of CC1 for further study.

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

Project description: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.

Identification of candidate genes involved in salt stress response at germination and seedling stages by QTL mapping in upland cotton

Project description:Salinity is a major abiotic stress at critical stages of seed germination and seedling establishment. Germination rate (GR) and field emergence rate (FER) are the key traits that determine the basic number of plants stand under field conditions. To explore molecular mechanisms in upland cotton under salt stress, a population of 177 recombinant inbred lines (RILs) and their parents were evaluated for seed germination traits (GP, germination potential; GR; FW, fresh weight; DW, dry weight; GL, germinal length) and seedling traits (FER; SH, seedling height; NL, Number of main stem leaves) in 2016-2018. Based on the linkage map contained 2,859 single nucleotide polymorphism (SNP) and simple sequence repeats (SSR) markers, traits under salt stress (E1) and normal condition, (E2) and the converted relative index (R-value) of three years’ trials were used to map quantitative trait loci (QTL). A total of three QTL and two clusters were detected as salt-tolerant QTL. Three QTL (qGR-Chr4-3, qFER-Chr12-3, qFER-Chr15-1) were detected under salt stress and R-value, which explained phenotypic variance of 9.62%-13.67%, and 4.2%-4.72%, 4.75%-8.96%, respectively. Two clusters (Loci-Chr4-2 and Loci-Chr5-4) harboring the QTL for four germination traits (GR, FER, GL, NL) and six seedling traits (GR, FER, DW, FW, SH, NL) were detected related under salt stress. A total of 691 genes were found in the candidate QTL or clusters. Among them, four genes (Gh_A04G1106, Gh_A05G3246, Gh_A05G3177, Gh_A05G3266) showed expression changes between sensitive and tolerant lines under salt stress, and were assigned as candidate genes in response to salt stress. The consistent salt-tolerance QTL identified in both germination and seedling stages will facilitate new information for cotton breeding.
