Subtilase SBT5.2 inactivates flagellin immunogenicity in the plant apoplast

Nature Communications
Most angiosperm plants recognise the 22-residue flagellin (flg22) epitope in bacterial flagellin via homologs of cell surface receptor FLS2 (flagellin sensitive-2) and mount pattern-triggered immune responses.

A DUF3455 domain‐containing protein promotes Ustilaginoidea virens infection and functions as a plant immune elicitor

New Plant Protection, EarlyView.
The fungal effector UvDUF1 from Ustilaginoidea virens not only promotes infection but also acts as a plant immunity elicitor, inducing broad‐spectrum disease resistance in rice and Nicotiana benthamiana. These results reveal its potential as a novel target for sustainable crop protection strategies.

Interplay of flg22-induced defence responses and nodulation in [PDF]

Journal of Experimental Botany, 2011
In this study the interplay between the symbiotic and defence signalling pathways in Lotus japonicus was investigated by comparing the responses to Mesorhizobium loti the symbiotic partner of L. japonicus and the elicitor flg22 a conserved peptide motif present in flagellar protein of a wide range of bacteria.

The Receptor-Like Kinase SERK3/BAK1 Is Required for Basal Resistance against the Late Blight Pathogen Phytophthora infestans in Nicotiana benthamiana [PDF]

, 2015
BACKGROUND The filamentous oomycete plant pathogen Phytophthora infestans causes late blight, an economically important disease, on members of the nightshade family (Solanaceae), such as the crop plants potato and tomato.

SIB1‐SEC23A undergo ER to chloroplast relocalization to mediate immunity in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
SEC23A mediates membrane trafficking between the endoplasmic reticulum (ER) and Golgi apparatus and interacts with the immunity protein SIGMA FACTOR‐BINDING PROTEIN1 in Arabidopsis. Under stress, both proteins relocate from the ER to chloroplasts, suppressing photosynthesis genes and enhancing defense genes.

Guard cell SLAC1-type anion channels mediate flagellin-induced stomatal closure [PDF]

, 2015
During infection plants recognize microbe-associated molecular patterns (MAMPs), and this leads to stomatal closure. This study analyzes the molecular mechanisms underlying this MAMP response and its interrelation with ABA signaling.

Discovery of ADP-Ribosylation and Other Plant Defense Pathway Elements Through Expression Profiling of Four Different Arabidopsis–Pseudomonas R-avr Interactions

Molecular Plant-Microbe Interactions, 2008
A dissection of plant defense pathways was initiated through gene expression profiling of the responses of a single Arabidopsis thaliana genotype to isogenic Pseudomonas syringae strains expressing one of four different cloned avirulence (avr) genes ...

Decoding MAPK cascades in plant immunity: Activation, regulation, integration, and pathogen manipulation

Journal of Integrative Plant Biology, EarlyView.
This review focuses on mitogen‐activated protein kinase (MAPK) activation and summarizes how plants regulate and integrate MAPK signaling in modulating plant immune responses. It also examines the effectors pathogens have evolved to manipulate MAPK activation and thereby inhibit plant immunity.

Functional analysis of Arabidopsis immune-related MAPKs uncovers a role for MPK3 as negative regulator of inducible defences [PDF]

, 2014
Background : Mitogen-activated protein kinases (MAPKs) are key regulators of immune responses in animals and plants. In Arabidopsis, perception of microbe-associated molecular patterns (MAMPs) activates the MAPKs MPK3, MPK4 and MPK6.

Single‐Cell Transcriptomics Reveals FLS2‐Dependent Hypoxia Signaling and ERF13‐Mediated Transcription During flg22‐Triggered Immunity

Advanced Science
The flagellin peptide flg22 activates FLAGELLIN‐SENSING 2 (FLS2)‐mediated immunity in Arabidopsis, leading to growth inhibition and oxidative burst. While these responses are well‐studied, their cell‐type‐specific regulation remains poorly understood ...
