Stem-Cell-Triggered Immunity Safeguards Cytokinin Enriched Plant Shoot Apexes from Pathogen Infection

Frontiers in Plant Science, 2014
Intricate mechanisms discriminate between friends and foes in plants. Plant organs deploy overlapping and distinct protection strategies. Despite vulnerability to a plethora of pathogens, the growing tips of plants grow bacteria free.

Flagellin peptide flg22 gains access to long-distance trafficking in Arabidopsis via its receptor, FLS2 [PDF]

Journal of Experimental Botany, 2017
Diverse pathogen-derived molecules, such as bacterial flagellin and its conserved peptide flg22, are recognized in plants via plasma membrane receptors and induce both local and systemic immune responses. The fate of such ligands was unknown: whether and by what mechanism(s) they enter plant cells and whether they are transported to distal tissues.

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

The brassinosteroid‐responsive protein OCTOPUS is a novel regulator of Arabidopsis thaliana immune signaling

Plant Direct, 2023
Phloem is a critical tissue for transport of photosynthates and extracellular signals in vascular plants. However, it also represents an ideal environment for pathogens seeking access to valuable host nutrients.

Rice Blast Pathogenesis and Resistance: Effector Strategies and Host Defense Mechanisms

Food and Energy Security, Volume 15, Issue 1, January/February 2026.
ABSTRACT Rice blast is the most significant disease affecting rice production, causing substantial yield loss and quality degradation. Previous studies have focused primarily on the genetic basis of pathogen resistance in rice. Recent studies have revealed the immune response mechanisms induced by pathogen‐associated molecular patterns in the pathogen ...

Polar‐localized EXO70G1 regulates root development in Arabidopsis thaliana

Journal of Integrative Plant Biology, Volume 68, Issue 1, Page 96-112, January 2026.
The putative exocyst subunit EXO70G1 exhibits apical‐basal polarity in Arabidopsis root cells; this polarity stabilizes membrane domains to facilitate targeting of the auxin transporter PIN‐FORMED2 during root development. ABSTRACT Cellular asymmetry, which represents a fundamental characteristic of cell polarity, is prominently illustrated by the ...

The activated SA and JA signaling pathways have an influence on flg22-triggered oxidative burst and callose deposition.

PLoS ONE, 2014
The first line of defense in plants against pathogens is induced by the recognition of microbe-associated molecular patterns (MAMP). Perception of bacterial flagellin (flg22) by the pattern recognition receptor flagellin-sensing 2 (FLS2) is the best ...

The VlMYB149‐VlHIPP30 Regulatory Module Enhances Grapevine Resistance to Botrytis cinerea by Activating the Antioxidant System and Copper Metabolism

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The VlMYB149‐VlHIPP30 module collaboratively facilitates Cu2+ accumulation and activates the ROS scavenging pathway to enhance the resistance to grey mould in grapevine. ABSTRACT Grapevine, as an important economic crop around the world, has generally poor disease resistance in planting.

An overexcited plant immunoreceptor : a hybrid FLS2 receptor that is active without flagellin

, 2022
Perception of bacterial flagellin by the receptor kinase AtFLS2 is a classic model for studying the molecular functioning of plant immunoreceptors. Although FLS2 receptors with a conserved ectodomain consisting of 28 leucine-rich repeats (LRRs) occur in a broad range of plant species, these FLS2 homologs display species-specific characteristics with ...

The Ralstonia solanacearum E3 Ligase Effector RipV1 Targets Plant U‐Box Domain‐Containing Receptor‐Like Cytoplasmic Kinases That Negatively Regulate Immunity in Nicotiana benthamiana

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The Ralstonia solanacearum Novel E3 Ligase effector RipV1 ubiquitinates and enhances the accumulation of the plant U‐box‐containing receptor‐like cytoplasmic protein RLCK‐IXb‐1 that negatively regulates immune signalling. ABSTRACT Plants detect microbe‐associated molecular patterns from pathogens via plasma membrane‐localised receptors, which activate ...
