    Negative regulation of ABA signaling by WRKY33 is critical for Arabidopsis immunity towards Botrytis cinerea 2100

    Shouan Liu et al.
    A genome-wide view of the gene regulatory network governed by WRKY33 has identified key targets that negatively regulate ABA biosynthesis to provide immunity against infection by a necrotrophic fungus.

    Prioritizing plant defence over growth through WRKY regulation facilitates infestation by non-target herbivores

    Ran Li et al.
    A chewing herbivore induced WRKY transcription factor induces jasmonate-dependent defences and supresses gibbererellin-dependent growth, the latter of which renders rice plants more susceptible to secondary infestation by a piercing-sucking herbivore.

    The transcriptional regulator BZR1 mediates trade-off between plant innate immunity and growth

    Rosa Lozano-Durán et al.
    The transcriptional regulator BZR1 acts as a molecular integrator of environmental cues regulating the trade-off between growth and innate immunity.

    A lectin receptor kinase as a potential sensor for extracellular nicotinamide adenine dinucleotide in Arabidopsis thaliana

    Chenggang Wang et al.
    Genetic and biochemical analyses demonstrate that cell-surface lectin receptors can potentially function as extracellular NAD+-binding receptors and provide direct evidence for extracellular NAD+ being a bona fide endogenous signaling molecule in plants.

    Parallel global profiling of plant TOR dynamics reveals a conserved role for LARP1 in translation

    M Regina Scarpin et al.
    Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.

    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.

    Multiple pairs of allelic MLA immune receptor-powdery mildew AVRA effectors argue for a direct recognition mechanism

    Isabel ML Saur et al.
    Allelic MLA immune receptors have an exceptional propensity to directly detect sequence-unrelated pathogen effectors and this feature might have facilitated functional diversification of the receptor in the host population.

    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 Phytophthora effector recruits a host cytoplasmic transacetylase into nuclear speckles to enhance plant susceptibility

    Haiyang Li et al.
    PsAvh52 modulates epigenetic modification to enhance the susceptibility of soybean to Phytophthora sojae infection.

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

    A Maqbool et al.
    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.
