    Stress induced gene expression drives transient DNA methylation changes at adjacent repetitive elements

    David Secco, Chuang Wang ... Ryan Lister
    Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.

    Natural epigenetic polymorphisms lead to intraspecific variation in Arabidopsis gene imprinting

    Daniela Pignatta, Robert M Erdmann ... Mary Gehring
    Individual scientists, scientific communities and scientific journals can do more to assess the publication of irreproducible results, to promote good science, and to increase the efficiency with which the scientific community self-corrects.

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

    Thierry Halter, Jingyu Wang ... Lionel Navarro
    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.

    H1 restricts euchromatin-associated methylation pathways from heterochromatic encroachment

    C Jake Harris, Zhenhui Zhong ... Steven E Jacobsen
    The efficient deployment of RdDM for transposon silencing is hierarchically controlled by the linker histone H1.

    Long non-coding RNA produced by RNA polymerase V determines boundaries of heterochromatin

    Gudrun Böhmdorfer, Shriya Sethuraman ... Andrzej T Wierzbicki
    Genome-wide identification of long non-coding RNAs produced by RNA Polymerase V identifies their role in heterochromatin maintenance on the boundaries of repressed regions.

    Non-canonical RNA-directed DNA methylation participates in maternal and environmental control of seed dormancy

    Mayumi Iwasaki, Lena Hyvärinen ... Luis Lopez-Molina
    Seed-specific and cold-induced DNA methylation is deposited in the seed progeny to form a transient and transgenerational memory of past environmental conditions to optimize seed germination timing.

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

    Liping Wang, Yi Ding ... Rosa Lozano-Duran
    The Cajal body is essential for plants to deploy antiviral DNA methylation.

    Histone H1 prevents non-CG methylation-mediated small RNA biogenesis in Arabidopsis heterochromatin

    Jaemyung Choi, David B Lyons, Daniel Zilberman
    Linker histone H1 and cytosine DNA methylation in contexts other than CG explain patterns of 24 nucleotide small RNA biogenesis in Arabidopsis thaliana.
