Receptor kinases sense extracellular signals and trigger intracellular signaling and physiological responses. However, how does signal binding to the extracellular domain activate the cytoplasmic kinase domain? Activation of the plant immunoreceptor Flagellin sensing2 (FLS2) by its bacterial ligand flagellin or the peptide-epitope flg22 coincides with rapid complex formation with a second recep...
Plant cell surface-localized receptor kinases such as FLS2, EFR, and CERK1 play a crucial role in detecting invading pathogenic bacteria. Upon stimulation by bacterium-derived ligands, FLS2 and EFR interact with BAK1, a receptor-like kinase, to activate immune responses. A number of Pseudomonas syringae effector proteins are known to block immune responses mediated by these receptors. Previous ...
BRASSINOSTEROID-INSENSITIVE 1 (BRI1) is a Leu-rich-repeat (LRR) receptor kinase that functions as a critical component of a transmembrane brassinosteroid (BR) receptor. It is believed that BRI1 becomes activated through heterodimerization with BAK1, a similar LRR receptor kinase, in response to BR signal. A yeast two-hybrid screen using the kinase domain of BRI1 identified an Arabidopsis thalia...
We read with great interest the article written by Gottlieb et al. [2009] where they report some intriguing polymorphism differences in aortic and blood tissues in the same individual. Actually, they were interested to perform case-control association analysis in AAA patients; however, instead of obtain a significant association, they realized that both diseased and non-diseased AA tissues show...
Some pattern recognition receptors (PRRs) in plants, such as PEPRs, sense endogenous, damage-associated molecular patterns (DAMPs) that are released during pathogen infection. In this issue of The EMBO Journal, Yamada and colleagues show that genetic or pathogen-induced depletion of Arabidopsis BAK1, a co-receptor for multiple PRRs, primes immune activation through PEPRs. The work illustrates a...
Introduction Since Gottlieb et al. [2009] published some intriguing sequence differences between DNA obtained from abdominal aortic (AA) tissue and blood, the scientific community has been attempting to understand their findings. Dr. Gottlieb’s group was primarily interested in performing case-control association analyses in abdominal aortic aneurysm (AAA) patients. However, instead of obtainin...
Innate immune responses are triggered by the activation of pattern-recognition receptors (PRRs). The Arabidopsis PRR FLAGELLIN-SENSING 2 (FLS2) senses bacterial flagellin and initiates immune signaling through association with BAK1. The molecular mechanisms underlying the attenuation of FLS2 activation are largely unknown. We report that flagellin induces recruitment of two closely related U-bo...
BAK1 is a co-receptor of BRI1 in early signaling pathways mediated by brassinosteroids (BRs) and is thought to play a major role in plant growth and development. As the role of BAK1 has not yet been fully elucidated then further research is required to explore its potential for use in genetic modification to improve crops. In this study, three BAK1 genes from the amphidiploid species Brassica r...
Programmed cell death (PCD) is a common host response to microbial infection [1-3]. In plants, PCD is associated with immunity to biotrophic pathogens, but it can also promote disease upon infection by necrotrophic pathogens [4]. Therefore, plant cell-suicide programs must be strictly controlled. Here we demonstrate that the Arabidopsis thaliana Brassinosteroid Insensitive 1 (BRI1)-associated r...
