TLDR
The dynamic nature of NB-LRR localization to different subcellular compartments before and after activation suggests that NB- LRRs may activate immune responses in multiple parts of the cell.About:

In Posidonia oceanica cadmium induces changes in DNA methylation and chromatin patterning
TL;DR: The data demonstrate that Cd perturbs the DNA methylation status through the involvement of a specific methyltransferase, linked to nuclear chromatin reconfiguration likely to establish a new balance of expressed/repressed chromatin.

Plant Innate Immunity: Perception of Conserved Microbial Signatures
TL;DR: In plants, coregulatory receptor kinases have been identified that not only are critical for the innate immune response but also serve an essential function in other regulatory signaling pathways.

How to build a pathogen detector: structural basis of NB-LRR function.
Frank L. W. Takken,Aska Goverse +1 more
TL;DR: In this article, the authors explore operational models of NB-LRRs based on recent advances in understanding their structure and show that, besides interdomain contacts, interactions with chaperones, the proteasome and effector baits are required to keep NB-lRRs in a signalling-competent, yet auto-inhibited state.

Bifurcation of Arabidopsis NLR Immune Signaling via Ca2+-Dependent Protein Kinases
Xiquan Gao,Xin Chen,Wenwei Lin,Sixue Chen,Dongping Lu,Yajie Niu,Lei Li,Cheng Cheng,Matthew McCormack,Jenq-Yunn Sheen,Libo Shan,Ping He +11 more
TL;DR: Functional genomic and biochemical genetic screens identified six closely related Arabidopsis Ca2+-dependent protein kinases (CPKs) in mediating bifurcate immune responses activated by NLR proteins, RPS2 and RPM1, and delineate b ifurcation of complex signaling mechanisms downstream of NLR immune sensors mediated by the myriad action of CPKs with distinct substrate specificity and subcellular dynamics.
Journal ArticleDOI
Two for all: receptor-associated kinases SOBIR1 and BAK1
TL;DR: The roles of SOBIR1 and BAK1 are compared as regulatory LRR-RLKs in immunity and development to show whether these proteins have a general regulatory role or are specifically required for the function of receptor complexes containing L RR-RLPs.

Plant immunity: towards an integrated view of plant―pathogen interactions
Peter N. Dodds,John P. Rathjen +1 more
TL;DR: The recent convergence of molecular studies of plant immunity and pathogen infection strategies is revealing an integrated picture of the plant–pathogen interaction from the perspective of both organisms, suggesting novel biotechnological approaches to crop protection.

Direct interaction of resistance gene and avirulence gene products confers rice blast resistance
TL;DR: It is reported here that transient expression of AVR‐Pita176 inside plant cells results in a Pi‐ta‐dependent resistance response, and data suggest that the AVR-Pita 176 protein binds directly to the Pi‐TA LRD region inside the plant cell to initiate a Pi-ta‐mediated defense response.

RIN4 Interacts with Pseudomonas syringae Type III Effector Molecules and Is Required for RPM1-Mediated Resistance in Arabidopsis
TL;DR: In Arabidopsis, RPM1 confers resistance against Pseudomonas syringae expressing either of two sequence unrelated type III effectors, AvrRpm1 or AvrB, and RIN4 positively regulates RPM1-mediated resistance yet is, formally, a negative regulator of basal defense responses.
Journal ArticleDOI
Arabidopsis RIN4 Is a Target of the Type III Virulence Effector AvrRpt2 and Modulates RPS2-Mediated Resistance
TL;DR: RIN4 is a point of convergence for the activity of at least three unrelated P. syringae type III effectors, and is suggested to be the target of the AvrRpt2 virulence function, and that perturbation of RIN4 activates RPS2.
