Effector‐Mediated Spatial Reprogramming of Glycolate Oxidase Subverts Peroxisomal and Membrane‐Associated ROS Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...

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.

Single-molecule analysis reveals the phosphorylation of FLS2 governs its spatiotemporal dynamics and immunity

eLife
The Arabidopsis thaliana FLAGELLIN-SENSITIVE2 (FLS2), a typical receptor kinase, recognizes the conserved 22 amino acid sequence in the N-terminal region of flagellin (flg22) to initiate plant defense pathways, which was intensively studied in the past ...

The Arabidopsis Receptor Kinase FLS2 Binds flg22 and Determines the Specificity of Flagellin Perception [PDF]

The Plant Cell, 2005
Abstract Flagellin, the main building block of the bacterial flagellum, acts as a pathogen-associated molecular pattern triggering the innate immune response in animals and plants. In Arabidopsis thaliana, the Leu-rich repeat transmembrane receptor kinase FLAGELLIN SENSITIVE2 (FLS2) is essential for flagellin perception.

Join the Green and Sustainable Team: Magnesium Oxide Nanoparticles Boost Broad‐Spectrum Viral Resistance in Solanaceae Plants

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant viruses are so harmful to crops. It is an urgent need to develop modern, environment‐friendly, and sustainable plant viral epidemic‐management strategies that are safe for both human health and the environment. The field of nanotechnology is gaining increased interest in plant science.

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.

H3K27me3‐Mediated Epigenetic Silencing of FgHMG1 Enables Fungal Host Immune Evasion

Plant Biotechnology Journal, EarlyView.
ABSTRACT Histone H3 lysine 27 trimethylation (H3K27me3) is essential for fungal pathogenicity, yet its contribution to pathogen–host interactions remains incompletely understood. Here, we profiled H3K27me3 dynamics in Fusarium graminearum during infection and identified 132 H3K27me3‐marked genes (FgHMGs).

Autoactive MtDMI1 Reprogrammes Immunity and Development in Tomato via Ethylene Signalling

Plant Biotechnology Journal, EarlyView.
ABSTRACT The Common Symbiosis Signalling Pathway (CSSP) underpins interactions between plants and microbes, yet its potential for crop improvement remains underexplored. Here, we investigated the gain‐of‐function mutant SPD1 (MtDMI1S760N), which constitutively activates the symbiotic signalling pathway in Medicago truncatula, by expressing it in tomato

3-Aminobenzamide Blocks MAMP-Induced Callose Deposition Independently of Its Poly(ADPribosyl)ation Inhibiting Activity

Frontiers in Plant Science, 2018
Cell wall reinforcement with callose is a frequent plant response to infection. Poly(ADP-ribosyl)ation is a protein post-translational modification mediated by poly(ADP-ribose) polymerases (PARPs).
