    Dimerisation of the PICTS complex via LC8/Cut-up drives co-transcriptional transposon silencing in Drosophila

    Evelyn L Eastwood et al.
    Heterochromatin formation at transposon loci depends on dimerisation of the effector complex that elicits co-transcriptional silencing and this requirement is fulfilled by co-option of the conserved dimerisation hub protein, Cut-up/LC8.

    Channel nuclear pore complex subunits are required for transposon silencing in Drosophila

    Marzia Munafò et al.
    By linking export and licensing of a piRNA precursor transcript, channel nuclear pore complex subunits Nup54 and Nup58 are specifically required to silence transposons in the Drosophila ovary.

    piRNA-guided co-transcriptional silencing coopts nuclear export factors

    Martin H Fabry et al.
    A member of the Drosophila Nuclear Export Factor (Nxf) family, Nxf2, forms part of the piRNA-dependent co-transcriptional silencing complex and is essential for transposon repression in fly ovaries.

    Ovaries absent links dLsd1 to HP1a for local H3K4 demethylation required for heterochromatic gene silencing

    Fu Yang et al.
    A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..

    Maternally inherited piRNAs direct transient heterochromatin formation at active transposons during early Drosophila embryogenesis

    Martin H Fabry et al.
    Maternally deposited Piwi-piRNA complexes co-transcriptionally repress transposable elements that transiently become active in somatic cells of the developing Drosophila embryo.

    Har-P, a short P-element variant, weaponizes P-transposase to severely impair Drosophila development

    Satyam P Srivastav et al.
    A female fertility syndrome in Drosophila called gonadal dysgenesis is caused by the P-transposase actively mobilizing a very short P-element variant that has been named the Har-P.

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

    Gudrun Böhmdorfer et al.
    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.

    Epigenetic reprogramming rewires transcription during the alternation of generations in Arabidopsis

    Michael Borg et al.
    Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.

    Regulation of rice root development by a retrotransposon acting as a microRNA sponge

    Jungnam Cho, Jerzy Paszkowski
    Retrotransposon-derived messenger RNA plays a critical role in rice root development via sequestration of miR171, which suggests a novel trans-acting regulation by transposable elements.

    Evolutionary dynamics of transposable elements in bdelloid rotifers

    Reuben W Nowell et al.
    An investigation of transposable element evolution in a group of long-term asexual animals shows that many of the predicted effects of asexuality are not observed.
