The membrane-bound Brassinosteroid insensitive1-associated receptor kinase1 (BAK1) is a common coreceptor in plants and regulates distinct cellular programs ranging from growth and development to defense against pathogens. BAK1 functions through binding to ligand-stimulated transmembrane receptors and activating their kinase domains via transphosphorylation. In the absence of microbes, BAK1 act...
Objectives To investigate the role of the microRNA-125a (miR-125a) and BAK1 in intervertebral disc degeneration (IDD). Materials and Methods Degenerative lumbar nucleus pulposus (NP) tissues were obtained from 193 patients who underwent resection, and normal controls consisted of normal NP tissues from 32 patients with traumatic lumbar fracture in our hospital. All patients were graded accord...
Phytosulfokine (PSK) is perceived by the leucine-rich repeat receptor kinase PSKR1 and promotes growth in Arabidopsis thaliana. PSKR1 is coexpressed with the CYCLIC NUCLEOTIDE-GATED CHANNEL gene CNGC17. PSK promotes protoplast expansion in the wild type but not in cngc17. Protoplast expansion is likewise promoted by cGMP in a CNGC17-dependent manner. Furthermore, PSKR1-deficient protoplasts do ...
Pathogens utilize effectors to suppress basal plant defense known as PTI (Pathogen-associated molecular pattern-triggered immunity). However, our knowledge of PTI suppression by filamentous plant pathogens, i.e. fungi and oomycetes, remains fragmentary. Previous work revealed that the co-receptor BAK1/SERK3 contributes to basal immunity against the potato pathogen Phytophthora infestans. Moreov...
The Arabidopsis BAK1 (BRI1 Associated receptor Kinase 1) was identified by a yeast two-hybrid screen as a specific interactor for BRI1, a critical component of a membrane brassinosteroid (BR) receptor. In yeast, BAK1/BRI1 interaction activates their kinase activities through transphosphorylation. BAK1 and BRI1 share similar gene expression and subcellular localization patterns and physically as...
BAK1 is a leucine-rich repeat receptor-like kinase that functions as a coreceptor with the brassinosteroid (BR) receptor BRI1 and the flagellin receptor FLS2, and as a negative regulator of programmed cell death. BAK1 has been shown to autophosphorylate on numerous serine/threonine sites in vitro as well as to transphosphorylate associated receptor kinases both in vitro and in planta. In the pr...
Plants and animals rely on innate immunity to prevent infections by detection of microbe-associated molecular patterns (MAMPs) through pattern-recognition receptors (PRRs). The plant PRR FLS2, a leucine-rich repeat-receptor kinase, recognizes bacterial flagellin and initiates immune signaling by association with another leucine-rich repeat-receptor-like kinase, BAK1. It remains unknown how the ...
Receptor-like kinases (RLKs) mediate cell-signaling pathways in Arabidopsis thaliana, including those controlling growth and development, immune response, and cell death. The RLK coreceptor BRI1-ASSOCIATED KINASE-1 (BAK1) partners with multiple ligand-binding RLKs and contributes to their signaling in diverse pathways. An additional RLK, BAK1-INTERACTING RECEPTOR-1 (BIR1), physically interacts ...
Signaling peptides play crucial roles in plant growth, development and defense. We report here that the Arabidopsis thaliana secreted peptide, ROOT MERISTEM GROWTH FACTOR 7 (RGF7), functions as an endogenous elicitor to trigger immunity. Expression of RGF7 precursor-encoding gene (preRGF7) is highly induced leaves upon infection by bacterial pathogen Pseudomonas syringae. The pathogen-responsiv...
Flagellin-sensing 2 (FLS2) is a leucine-rich repeat/transmembrane domain/protein kinase (LRR-RLK) that is the plant receptor for bacterial flagellin or the flagellin-derived flg22 peptide. Previous work has shown that after flg22 binding, FLS2 releases BIK1 kinase and homologs and associates with BAK1 kinase, and that FLS2 kinase activity is critical for FLS2 function. However, the detailed mec...
