    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.

    Two mechanisms regulate directional cell growth in Arabidopsis lateral roots

    Charlotte Kirchhelle et al.
    In lateral roots, cells employ a novel pathway to cell edges to control directional growth, which acts independently of the leading paradigm of oriented deposition of cellulose microfibrils at faces.

    Arabidopsis FORGETTER1 mediates stress-induced chromatin memory through nucleosome remodeling

    Krzysztof Brzezinka et al.
    Environmentally-mediated gene induction is extended beyond the duration of an external cue by sustaining a nucleosome-depleted chromatin structure.

    The Arabidopsis thaliana mobilome and its impact at the species level

    Leandro Quadrana et al.
    Population genomics in Arabidopsis thaliana uncovers an extensive repertoire of active transposable element families at the species level and reveals their importance as a source of rare alleles with large effects.

    Expansion of the circadian transcriptome in Brassica rapa and genome-wide diversification of paralog expression patterns

    Kathleen Greenham et al.
    Whole genome duplication in Brassica rapa is accompanied by both expansion of the circadian transcriptome and widespread temporal reconfiguration of gene regulatory networks consistent with subfunctionalization among pairs of paralogs.

    Nanopore direct RNA sequencing maps the complexity of Arabidopsis mRNA processing and m6A modification

    Matthew T Parker et al.
    Sequencing mRNA directly with nanopores can reveal the authentic combinations of multiple mRNA processing events in full-length mRNA molecules in addition to identifying base modifications.

    Arabidopsis RCD1 coordinates chloroplast and mitochondrial functions through interaction with ANAC transcription factors

    Alexey Shapiguzov et al.
    Signalling and metabolic interactions of the plant energy organelles, chloroplasts and mitochondria, depend on the nuclear regulatory protein RCD1.

    POWERDRESS interacts with HISTONE DEACETYLASE 9 to promote aging in Arabidopsis

    Xiangsong Chen et al.
    Genetic and biochemical studies reveal how a histone deacetylase acts together with other chromatin regulators to promote the onset of plant aging.

    Natural haplotypes of FLM non-coding sequences fine-tune flowering time in ambient spring temperatures in Arabidopsis

    Ulrich Lutz et al.
    Gene expression changes associated with polymorphisms in non-coding sequences of the flowering time regulator FLM directly influence flowering time in ambient temperature in Arabidopsis over an extended vegetative period.
