Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe-associated molecular patterns. [PDF]

New Phytol
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

The phloem-resident OCTOPUS protein is a novel regulator of flg22-induced responses in Arabidopsis thaliana [PDF]

bioRxiv, 2022
Phloem is a critical tissue that transports photosynthates and extracellular signals in vascular plants. Although a functional phloem is necessary for plant health, it is also an ideal environment for pathogens to access host nutrients to promote ...

Flg22-Triggered Immunity Negatively Regulates Key BR Biosynthetic Genes [PDF]

Frontiers in Plant Science, 2015
In plants, activation of growth and activation of immunity are opposing processes that define a trade-off. In the past few years, the growth-promoting hormones brassinosteroids (BR) have emerged as negative regulators of pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI), promoting growth at the expense of defense.

The secreted redox sensor roGFP2-Orp1 reveals oxidative dynamics in the plant apoplast. [PDF]

Plant Biol (Stuttg)
Using the secreted redox biosensor roGFP2‐Orp1, we reveal differences in extracellular (apoplastic) oxidative processes between and within species, depending on cell type and immune signalling. Abstract Specific generation of reactive oxygen species (ROS) is important for signalling and defence in many organisms. In plants, different types of ROS serve

The Intracellularly Acting Effector Foa3 Suppresses Defense Responses When Infiltrated Into the Apoplast

Frontiers in Plant Science, 2022
Plant pathogens employ secreted proteins, among which are effectors, to manipulate and colonize their hosts. A large fraction of effectors is translocated into host cells, where they can suppress defense signaling.

Analysis of Non-Coding RNAs and N6-Methyladenosine-Modified Genes in Response to flg22 in Grape Immunity. [PDF]

Plant Biotechnol J
Grape (Vitis vinifera) is susceptible to fungal pathogens and, consequently, severe yield losses. Investigating the immune mechanisms of the disease‐resistant Chinese wild grapes is crucial for developing sustainable disease resistance technologies. Here,

Reported differences in the flg22 response of the null mutation of AtRGS1 correlates with fixed genetic variation in the background of Col-0 isolates [PDF]

Plant Signalling & Behavior, 2021
A role for the heterotrimeric G protein complex in the induction of a transient burst of reactive oxygen species (ROS) by the Microbial-Associated Molecular Pattern, flg22, a 22-amino acid peptide derived from bacterial flagella, is well established ...

Defence signalling triggered by Flg22 and Harpin is integrated into a different stilbene output in Vitis cells. [PDF]

PLoS ONE, 2012
Plants can activate defence to pathogen attack by two layers of innate immunity: basal immunity triggered by pathogen-associated molecular pattern (PAMP) triggered immunity (PTI) and effector-triggered immunity (ETI) linked with programmed cell death ...

Sterols regulate endocytic pathways during flg22-induced defense responses in Arabidopsis [PDF]

Development, 2018
The plant transmembrane receptor kinase FLAGELLIN SENSING 2 (FLS2) is critical for innate immunity. Although previous studies have reported FLS2-mediated signal transduction and endocytosis via the clathrin-mediated pathway, whether additional endocytic pathways affect FLS2-mediated defense responses remains unclear.

Novel roles for Arabidopsis dynamin-related proteins DRP1A and DRP2B in resistance against Botrytis cinerea fungal infection

Plant Signaling & Behavior, 2022
Arabidopsis DYNAMIN-RELATED PROTEIN1A (AtDRP1A) and AtDRP2B are large GTPases that function together in endocytosis for effective cytokinesis, cell enlargement and development. A recent study shows that these DRPs contribute to ligand-induced endocytosis
