“…Recently, the roles of Cr RLK1L proteins in regulating agronomic traits have begun to be appreciated in crop species ( Table 1 ). In general, Cr RLK1L proteins play versatile roles in plant growth and development, reproduction, hormone signaling, stress responses, immunity ( Escobar-Restrepo et al., 2007 ; Guo et al., 2009 , 2018 ; Duan et al., 2010 , 2014 ; Yu et al., 2012 , 2014 ; Haruta et al., 2014 ; Li et al., 2015 , 2016a ; Mao et al., 2015 ; Chen et al., 2016 ; Du et al., 2016 ; Ge et al., 2017 , 2019 ; Mecchia et al., 2017 ; Stegmann et al., 2017 ; Chakravorty et al., 2018 ; Feng et al., 2018 ; Franck et al., 2018 ; Gonneau et al., 2018 ; Hansen et al., 2019 ; Wang et al., 2020a ; Zhou and Zhang, 2020 ), energy production and RNA metabolism ( Xu et al., 2019 ; Zhu et al., 2020a ; Wang et al., 2020b ).…”

“…Additionally, ATL6, an E3 ubiquitin ligase, directly interacts with FER, destabilizing 14-3-3 proteins, which modulate the C/N balance and signaling ( Xu et al., 2019 ). FER-like receptors 1 and 2 (FLR1 and FLR2) from rice are also involved in plant height, branching and tillering as well as male gametophyte development ( Li et al., 2016a ) and negatively regulate immunity against rice blast. FLR2 negatively modulates fungus-triggered ROS associated with rice blast.…”

Plants perceive various external and internal signals to self-modulate biological processes through members of the receptor-like kinase (RLK) family, among which Catharanthus roseus receptor-like kinase 1-like ( Cr RLK1L) proteins with their ligands, rapid alkalinization factor (RALF) peptides, have attracted considerable interest. FERONIA (FER), a Cr RLK1L member, was initially reported to act as a major plant cell growth modulator in distinct tissues. Subsequently, the RALF–FER pathway was confirmed to function as an essential regulator of plant stress responses, including but not limited to immune responses. Furthermore, the RALF–FER pathway modulates immune responses and cell growth in a context-specific manner, and the vital roles of this pathway are beginning to be appreciated in crop species. The recent remarkable advances in understanding the functions and molecular mechanisms of the RALF–FER pathway have also raised many interesting questions that need to be answered in the future. This review mainly focuses on the roles of FER and other Cr RLK1L members in modulating immune responses in the context of cell growth in response to their RALF peptide ligands and presents a brief outlook for future research.

“…FER also regulates fruit ripening in strawberry [ 9 ] and tomato [ 10 ] via ethylene biosynthesis regulation [ 7 ]. Our recent work has shown that two FER-like receptor ( FLR ) genes in rice are crucial for cell growth [ 11 ]. In addition, FER is involved in biotic and abiotic stress responses.…”

EBP1 nuclear accumulation negatively feeds back on FERONIA-mediated RALF1 signaling

et al. 2018

FERONIA (FER), a plasma membrane receptor-like kinase, is a central regulator of cell growth that integrates environmental and endogenous signals. A peptide ligand rapid alkalinization factor 1 (RALF1) binds to FER and triggers a series of downstream events, including inhibition of Arabidopsis H+-ATPase 2 activity at the cell surface and regulation of gene expression in the nucleus. We report here that, upon RALF1 binding, FER first promotes ErbB3-binding protein 1 (EBP1) mRNA translation and then interacts with and phosphorylates the EBP1 protein, leading to EBP1 accumulation in the nucleus. There, EBP1 associates with the promoters of previously identified RALF1-regulated genes, such as CML38, and regulates gene transcription in response to RALF1 signaling. EBP1 appears to inhibit the RALF1 peptide response, thus forming a transcription–translation feedback loop (TTFL) similar to that found in circadian rhythm control. The plant RALF1-FER-EBP1 axis is reminiscent of animal epidermal growth factor receptor (EGFR) signaling, in which EGF peptide induces EGFR to interact with and phosphorylate EBP1, promoting EBP1 nuclear accumulation to control cell growth. Thus, we suggest that in response to peptide signals, plant FER and animal EGFR use the conserved key regulator EBP1 to control cell growth in the nucleus.

Stem cell homeostasis by the WUS-CLV negative feedback loop is generally conserved across species; however, its links with other meristem regulators may have species-specific distinctions, rice being an example. We characterize rice OsbZIP47 for vegetative and inflorescence phenotypes in knockdown (OsbZIP47KD) transgenics and uncover its role in meristem maintenance and developmental progression. The shoot apical meristem (SAM) size in five day old OsbZIP47KD seedlings, was reduced as compared to the wild-type (WT). Whereas SAM in older twenty-five-day OsbZIP47KD plants was larger with increased size for L1 and underlying cells. We tested protein interactions of OsbZIP47 with other transcription factors and found partnerships with OsMADS1, RFL, and OSH1. Results from meta-analysis of deregulated panicle transcriptome datasets, in OsbZIP47KD, OsMADS1KD and RFLKD knockdown transgenics, and OSH1 genome-wide binding sites divulge potential targets coregulated by OsbZIP47, OsMADS1, OSH1 and RFL. Transcript analysis in OsbZIP47KD SAM and panicles showed abnormal gene expression for CLAVATA peptide-like signaling FON2-LIKE CLE PROTEIN1 (FCP1), FLORAL ORGAN NUMBER 2 (FON2), and hormone pathway: cytokinin (CK) Isopenteyltransferase2 (OsIPT2), Isopenteyltransferase8 (OsIPT8); auxin biosynthesis OsYUCCA6, OsYUCCA7; gibberellic acid (GA) biosynthesis GA20Ox1, GA20Ox4 and brassinosteriod biosynthesis CYP734A4 genes. The effects on ABBERANT PANICLE ORGANIZATION1 (APO1), OsMADS16, and DROOPING LEAF relate to second and third whorl organ phenotypes in OsbZIP47KD florets. Further, we demonstrate that OsbZIP47 redox status affects its DNA binding to cis elements in the FCP1 locus. Taken together, we provide insights on unique functional roles for OsbZIP47 in rice shoot meristem maintenance, its progression through inflorescence branching and floret development.
