Target Background

Function
Receptor-like protein kinase that mediates the female control of male gamete delivery during fertilization, including growth cessation of compatible pollen tubes ensuring a reproductive isolation barriers, by regulating MLO7 subcellular polarization upon pollen tube perception in the female gametophyte synergids. Required for cell elongation during vegetative growth, mostly in a brassinosteroids- (BR-) independent manner. Acts as an upstream regulator for the Rac/Rop-signaling pathway that controls ROS-mediated root hair development. Seems to regulate a cross-talk between brassinosteroids and ethylene signaling pathways during hypocotyl elongation. Negative regulator of brassinosteroid response in light-grown hypocotyls, but required for brassinosteroid response in etiolated seedlings. Mediates sensitivity to powdery mildew (e.g. Golovinomyces orontii). Positive regulator of auxin-promoted growth that represses the abscisic acid (ABA) signaling via the activation of ABI2 phosphatase. Required for RALF1-mediated extracellular alkalinization in a signaling pathway preventing cell expansion.
Gene References into Functions
  1. suppression of RALF1 gene expression, similar to disruption of the FER gene, rendered plants hypersensitive to ABA. These results formulated a mechanism for ABA activation of FER and for cross-talk between ABA and peptide hormone RALF in the control of plant growth and responses to stress signals PMID: 27566404
  2. LRE and FERONIA jointly function in pollen tube reception at the interface of the synergid cell and pollen tube. PMID: 27081182
  3. FER acts as a RALF-regulated scaffold that modulates receptor kinase complex assembly. A similar scaffolding mechanism may underlie FER function in other signaling pathways. PMID: 28104890
  4. The results of these experiments are consistent with a model in which kinase-mediated phosphorylation within the C-terminal region is inhibitory and regulates catalytic activity. These data represent a step further toward understanding the molecular basis for the protein kinase catalytic activity of FERONIA and show promise for future characterization of eukaryotic membrane proteins. PMID: 28235802
  5. We propose that FER receptor kinase, in response to environmental stress and plant hormones such as auxin and brassinolide, interacts with S-adenosylmethionine (SAM) synthases and down-regulates ethylene biosynthesis. PMID: 25988356
  6. Glycosylphosphatidylinositol-anchored proteins LLG1and LORELEI act as necessary chaperones and co-receptors for FERONIA receptor kinase signaling in Arabidopsis. PMID: 26052747
  7. An Arabidopsis mutant lacking the receptor-like kinase FERONIA shows severely altered Ca(2+) signaling and growth responses to different forms of mechanical perturbation. Ca(2+) signals are either abolished or exhibit qualitatively different signatures. PMID: 25127214
  8. Three independent T-DNA insertion lines for FERONIA and its pollen-specific homolog ANXUR2 showing deformed pollen phenotypes caused by chromosomal translocations, were identified. PMID: 24874868
  9. FER controls seed size in Arabidopsis thaliana PMID: 24482438
  10. a secreted peptide, RALF (rapid alkalinization factor), suppresses cell elongation of the primary root by activating the cell surface receptor FERONIA in Arabidopsis thaliana. PMID: 24458638
  11. FERONIA receptor kinase pathway suppresses abscisic acid signaling in Arabidopsis by activating ABI2 phosphatase. PMID: 22908257
  12. These findings position the THESEUS 1/FERONIA family RLKs as surface regulators and potential cell wall sensors capable of broadly and profoundly impacting cellular pathways in response to diverse signals. PMID: 21963060
  13. study shows pollen tube (PT) reception and powdery mildew (PM) infection share molecular components; NORTIA, discovered in context of PM resistance, and FER control PT reception; fer mutants also display PM resistance revealing a new function for FER PMID: 21071669
  14. FER is an upstream regulator for the RAC/ROP-signaled pathway that controls ROS-mediated root hair development. PMID: 20876100
  15. Pollen tube discharge is controlled by an interaction between the synergids expressing SRN/FER and the central cell expressing FIS genes. PMID: 19825570
  16. FER protein accumulates asymmetrically in the synergid membrane at the filiform apparatus; findings show that female control of pollen tube reception is based on a FER-dependent signaling pathway, which may play a role in reproductive isolation barriers PMID: 17673660
  17. 3 related receptor-like kinases, HERCULES1, THESEUS1, and FERONIA, transcriptionally induced by brassinosteroids are charcterized in this study. PMID: 19383785
  18. Disruption of the pollen-expressed FERONIA homologs ANXUR1 and ANXUR2 triggers pollen tube discharge PMID: 19736323
