Conserved fungal effector suppresses PAMP-triggered immunity by targeting plant immune kinases

Molecular components of PAMP-triggered oxidative burst in plant immunity

Xanthomonas T3S Effector XopN Suppresses PAMP-Triggered Immunity and Interacts with a Tomato Atypical Receptor-Like Kinase and TFT1.

XopN is a virulence factor from Xanthomonas campestris pathovar vesicatoria (Xcv) that is translocated into tomato (Solanum lycopersicum) leaf cells by the pathogen's type III secretion system. Xcv DeltaxopN mutants are impaired in growth and have reduced ability to elicit disease symptoms in susceptible tomato leaves. We show that XopN action in planta reduced pathogen-associated molecular pat...

Effector triggered immunity

Pathogenic bacteria produce virulence factors called effectors, which are important components of the infection process. Effectors aid in pathogenesis by facilitating bacterial attachment, pathogen entry into or exit from the host cell, immunoevasion, and immunosuppression. Effectors also have the ability to subvert host cellular processes, such as hijacking cytoskeletal machinery or blocking p...

the role of micrornas and phytohormones in plant immune system

the plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. during the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ros signaling, hormone activation and gene expression reprogramming. in plants, micrornas (mirnas) are key post-transcript...

Acetylation of an NB-LRR Plant Immune-Effector Complex Suppresses Immunity

Modifications of plant immune complexes by secreted pathogen effectors can trigger strong immune responses mediated by the action of nucleotide binding-leucine-rich repeat immune receptors. Although some strains of the pathogen Pseudomonas syringae harbor effectors that individually can trigger immunity, the plant's response may be suppressed by other virulence factors. This work reveals a robu...
