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

Organelle-targeted biosensors reveal distinct oxidative events during pattern-triggered immune responses

Plant Physiology, 2022
AbstractReactive oxygen species are produced in response to pathogens and pathogen-associated molecular patterns, as exemplified by the rapid extracellular oxidative burst dependent on the NADPH oxidase isoform RESPIRATORY BURST OXIDASE HOMOLOG D (RBOHD) in Arabidopsis (Arabidopsis thaliana).

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.

Cooperative regulation of PBI1 and MAPKs controls WRKY45 transcription factor in rice immunity

Nature Communications, 2022
The U-box type ubiquitin ligase PUB44 positively regulates pattern-triggered immunity in rice. Here the authors identify a PUB44 substrate whose degradation is required for activation of the WRKY45 transcription factor upon immune elicitation.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Activation of TIR signaling is required for pattern-triggered immunity [PDF]

, 2020
AbstractPlant immune responses are mainly activated by two types of receptors. Plasma membrane-localized pattern recognition receptors (PRRs) recognize conserved features of microbes, and intracellular nucleotide-binding leucine rich repeat receptors (NLRs) recognize effector proteins from pathogens.

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 ...

The Trihelix transcription factor GT2-like 1 (GTL1) promotes salicylic acid metabolism, and regulates bacterial-triggered immunity.

PLoS Genetics, 2018
The Trihelix Transcription factor GT2-like 1 (GTL1) was previously shown to be a key regulator of ploidy-dependent trichome growth and drought tolerance. Here, we report that GTL1 plays an important role in coordinating plant immunity.
