    Emergence and diversification of a highly invasive chestnut pathogen lineage across southeastern Europe

    Lea Stauber et al.
    The chestnut blight fungus has successfully established an intermediary, diverse European bridgehead population, giving rise to a highly invasive clonal lineage spreading across southeastern Europe.

    The Arabidopsis active demethylase ROS1 cis-regulates defence genes by erasing DNA methylation at promoter-regulatory regions

    Thierry Halter et al.
    Active DNA demethylation at some defence gene promoters is causal for DNA binding of WRKY transcription factors as well as for transcriptional activation of these genes during plant immune response.

    A fungal member of the Arabidopsis thaliana phyllosphere antagonizes Albugo laibachii via a GH25 lysozyme

    Katharina Eitzen et al.
    A basidiomycete yeast closely related to fungal smuts is an antagonistic microbe in the Arabidopsis leaf phyllosphere that inhibits infection by Albugo laibachii via a GH25 hydrolase with lysozyme activity.

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

    David E Cook et al.
    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.

    A virus-encoded protein suppresses methylation of the viral genome through its interaction with AGO4 in the Cajal body

    Liping Wang et al.
    The Cajal body is essential for plants to deploy antiviral DNA methylation.

    KATANIN-dependent mechanical properties of the stigmatic cell wall mediate the pollen tube path in Arabidopsis

    Lucie Riglet et al.
    KATANIN1 in stigma papilla cells prevents disordered pollen tube growth and straightens pollen tube direction, allowing the pollen tube to find its correct path to the underlying female tissues.

    Oomycete small RNAs bind to the plant RNA-induced silencing complex for virulence

    Florian Dunker et al.
    Small RNAs of distantly related plant pathogens, such as fungi and oomycetes, hijack the plant RNA-induced silencing complex to favor host infection.

    An N-terminal motif in NLR immune receptors is functionally conserved across distantly related plant species

    Hiroaki Adachi et al.
    The MADA motif is functionally conserved across NLRs from distantly related plants and has degenerated in sensor NLRs over evolutionary time.

    Compensatory sequence variation between trans-species small RNAs and their target sites

    Nathan R Johnson et al.
    Superfamilies of trans-species small RNAs from the parasitic plant Cuscuta have sequence variation that correspond to synonymous site variation in host plant target mRNAs.

    A new family of cell surface located purine transporters in Microsporidia and related fungal endoparasites

    Peter Major et al.
    Transporters shared by fungal intracellular parasites provide new insights into the evolution of nucleotide and energy parasitism.
