Host-induced bacterial cell wall decomposition mediates pattern-triggered immunity in Arabidopsis

eLife, 2014
Peptidoglycans (PGNs) are immunogenic bacterial surface patterns that trigger immune activation in metazoans and plants. It is generally unknown how complex bacterial structures such as PGNs are perceived by plant pattern recognition receptors (PRRs) and

Enhancing crop innate immunity: new promising trends

Frontiers in Plant Science, 2014
Plants are constantly exposed to potentially pathogenic microbes present in their surrounding environment. Due to the activation of the pattern-triggered immunity (PTI) response that largely relies on accurate detection of pathogen- or microbe-associated

Hypoxia represses pattern-triggered immune responses in Arabidopsis

Plant Physiology
Abstract Biotic and abiotic stresses frequently co-occur in nature, yet relatively little is known about how plants coordinate the response to combined stresses. Protein degradation by the ubiquitin/proteasome system is central to the regulation of multiple independent stress response pathways in plants.

The MAP4 kinase NbM4K3 regulates immune responses in Nicotiana benthamiana

Phytopathology Research
The mitogen-activated protein kinase kinase kinase kinase (M4K) family is evolutionarily conserved across plants and animals. In Arabidopsis, the protein kinase SIK1, an M4K member, is known to positively modulate reactive oxygen species (ROS) production

Unlocking Nature's Defense: Plant Pattern Recognition Receptors as Guardians Against Pathogenic Threats

Molecular Plant-Microbe Interactions
Embedded in the plasma membrane of plant cells, receptor kinases (RKs) and receptor proteins (RPs) act as key sentinels, responsible for detecting potential pathogenic invaders.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Unseen Struggles: How Plant-Parasitic Nematodes Manipulate ROS Signaling in Host Plants

Molecular Plant-Microbe Interactions
Reactive oxygen species (ROS) play a central role in plant defense, especially during interactions with plant-parasitic nematodes (PPNs). These molecules act as early signals that activate immune responses and help reinforce plant cell walls to block ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Apoplastic invasion patterns triggering plant immunity: plasma membrane sensing at the frontline [PDF]

Molecular Plant Pathology, 2019
Summary Plants are able to effectively cope with invading pathogens by activating an immune response based on the detection of invasion patterns (IPs) originating from the pathogen or released by the plant after infection. At a first level, this perception takes place at the plasma membrane through cell surface immune receptors and ...
