  1. ...-CREs in Atlantic salmon, we carried out massive parallel reporter assays (MPRAs), specifically an ATAC-STARR-seq experiment, in salmon primary liver cells (Fig. 6A). This method assesses the ability of random DNA fragments from accessible chromatin to modulate transcription levels (Wang et al. 2018). In total, 4...
  2. ...in a pan context. We then generated a unified TE annotation for a maize pan derived from 26 reference-quality s, which reveals an excess of 35.1 Mb of TE sequences per in tropical maize relative to temperate maize. A small number (n = 216) of TE families, mainly LTR retrotransposons, drive...
  3. ...). The strong signature of species specificity observed for aphid TE families suggests that the independent gain of new TE families is a major factor driving aphid TE landscapes. Collectively, these findings suggest a dynamic repeat landscape in aphid s, characterized by relatively frequent gain and turnover...
  4. ...Large-scale detection and characterization of interchromosomal rearrangements in normozoospermic bulls using massive genotype and phenotype data sets Jeanlin Jourdain,1,2 Harmonie Barasc,3 Thomas Faraut,3 Anne Calgaro,3 Nathalie Bonnet,3 Camille Marcuzzo,4 Amandine Suin,4 Anne Barbat,2 Chris Hozé,1...
  5. ...considered as genomic parasites threatening host integrity, even though they can be a source of genetic innovation (Cosby et al. 2019; Capy 2021). Host defense pathways counteract the potentially detrimental effects of transposon invasion. In eukaryotes, small RNA (sRNA)-dependent post...

PRDM9 drives evolutionary erosion of hotspots in Mus musculus through haplotype-specific initiation of meiotic recombination. PLoS Genet...
  7. ...carry their own promoters and regulatory sequences. Consequently, metazoans have evolved a variety of defenses to control their spread, most notably the piRNA system (Aravin et al. 2007; Czech and Hannon 2016) and the previously mentioned KZNFs (Ecco et al. 2017; Bruno et al. 2019). A hallmark of both...
  8. ...of spermatogenesis: meiotic prophase (pachytene spermatocytes, hereafter “meiotic”) and following completion of meiotic divisions (round spermatids, hereafter “postmeiotic”) from adult mouse testes by gravity sedimentation (STA-PUT) (Bellvé et al. 1977; Bellvé 1993). Purity was estimated at 80%–85% for meiotic...
  9. ...expansion on the P. picta X Chromosome, which is absent in closely related species that lack dosage compensation. Taken together, our results present compelling support that a disruptive wave of repetitive element insertions carrying YY1 motifs resulted in the remodeling of the X Chromosome epigenomic...
  10. ...the met1 DNA methyltransferase mutant to investigate the role of heterochromatin in SPO11-1-oligo distributions. Epigenetic activation of meiotic DSBs in proximity to centromeres and transposons occurred in met1 mutants, coincident with reduced nucleosome occupancy, gain of transcription, and H3K4me3...
