    A unique chromatin profile defines adaptive genomic regions in a fungal plant pathogen

    David E Cook, H Martin Kramer ... Bart P H J Thomma
    Assessment of DNA methylation, histone modifications, and DNA accessibility revealed that physical DNA characteristics are associated with adaptive genome evolution in the broad host range plant pathogenic fungus Verticillium dahliae.

    Evolutionary transitions between beneficial and phytopathogenic Rhodococcus challenge disease management

    Elizabeth A Savory, Skylar L Fuller ... Jeff H Chang
    The horizontal acquisition of virulence plasmids is potentiated by production practices in plant nurseries and is sufficient to transition Rhodococcus from being beneficial to being pathogenic.

    A complete toolset for the study of Ustilago bromivora and Brachypodium sp. as a fungal-temperate grass pathosystem

    Franziska Rabe, Jason Bosch ... Armin Djamei
    The establishment of Ustilago bromivora and Brachypodium as a biotrophic model system provides the foundation for studying new aspects of plant-pathogen interactions and for answering questions about fungal sex and speciation.

    Exosomes mediate horizontal transmission of viral pathogens from insect vectors to plant phloem

    Qian Chen, Yuyan Liu ... Taiyun Wei
    An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.

    Structural basis of pathogen recognition by an integrated HMA domain in a plant NLR immune receptor

    A Maqbool, H Saitoh ... MJ Banfield
    Structure/function studies of a plant pathogen effector in complex with a host disease resistance protein domain reveal the molecular basis for recognition and underpin future engineering of immunity in crops.

    Pathogen effectors and plant immunity determine specialization of the blast fungus to rice subspecies

    Jingjing Liao, Huichuan Huang ... Jean-Benoit Morel
    Specialized fungal pathogen populations infect rice varieties with contrasting immune systems co-cultivated in a traditional agro-system, indicating the relevance of crop diversity to restricting epidemics in the landscape.

    Plant SYP12 syntaxins mediate an evolutionarily conserved general immunity to filamentous pathogens

    Hector M Rubiato, Mengqi Liu ... Mads E Nielsen
    To effectively ward off some of the most damaging groups of filamentous pathogens, plants rely on an evolutionarily conserved syntaxin function to block the pathogen from entering the host cell and proliferate.

    The plant pathogen Pseudomonas aeruginosa triggers a DELLA-dependent seed germination arrest in Arabidopsis

    Hicham Chahtane, Thanise Nogueira Füller ... Luis Lopez-Molina
    Arabidopsis seed germination can be repressed by a Pseudomonas factor.

    Cytoplasmic retention and degradation of a mitotic inducer enable plant infection by a pathogenic fungus

    Paola Bardetti, Sónia Marisa Castanheira ... José Pérez-Martín
    Degradation of a mitotic inducer coordinates the transition of two successive cell cycle arrests during the infective process of a plant pathogenic fungus.

    Soil-borne fungi alter the apoplastic purinergic signaling in plants by deregulating the homeostasis of extracellular ATP and its metabolite adenosine

    Christopher Kesten, Valentin Leitner ... Clara Sanchez-Rodriguez
    Biochemical and in vivo physiology imaging reveal that plant pathogens actively imbalance the apoplastic eAdo/eATP levels as a virulence mechanism.
