    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.

    The MADS-box transcription factor PHERES1 controls imprinting in the endosperm by binding to domesticated transposons

    Rita A Batista et al.
    Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.

    An epigenetic switch ensures transposon repression upon dynamic loss of DNA methylation in embryonic stem cells

    Marius Walter et al.
    The various transposon families of the mammalian genome can adopt different types of repressive chromatin responses upon DNA methylation loss.

    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.

    Fine interaction profiling of VemP and mechanisms responsible for its translocation-coupled arrest-cancelation

    Ryoji Miyazaki et al.
    Time-resolved and site-directed in vivo photo-crosslinking analysis of VemP allows identification of both cis- and trans-elements required for its regulated arrest-cancelation.

    An ER translocon for multi-pass membrane protein biogenesis

    Philip T McGilvray et al.
    A set of ER-localized membrane proteins whose loss causes developmental diseases in humans, assemble with Sec61 into a translocon that facilitates the biogenesis of hundreds of different multi-pass membrane proteins.

    The Sec61 translocon limits IRE1α signaling during the unfolded protein response

    Arunkumar Sundaram et al.
    Building on previous work (Plumb et al., 2015), it is shown that the Sec61 translocon controls the oligomerization, activation and inactivation of Ire1α during endoplasmic reticulum stress.

    A new role for histone demethylases in the maintenance of plant genome integrity

    Javier Antunez-Sanchez et al.
    Plants reset chromatin marks during sexual reproduction to safeguard the stability of the genome.

    Functional genomics of lipid metabolism in the oleaginous yeast Rhodosporidium toruloides

    Samuel T Coradetti et al.
    Using barcoded mutagenesis and a high-throughput genetic screen results in the identification of 150 genes that affect lipid accumulation in a non-model yeast system.
