Rapid climate change is placing many marine species at risk of local extinction. Recent studies show that epigenetic mechanisms (e.g. DNA methylation, histone modifications) can facilitate both within and transgenerational plasticity to cope with changing environments. However, reprogramming (erasure re-establishment marks) during gamete early embryo development may hinder inheritance. Most our knowledge about stems from mammals model organisms, whereas the prevalence extent among non-model wild populations rarely investigated. Moreover, whether dynamics are sensitive environmental conditions not well known, representing a key gap in pursuit identify underlying links between parental exposure patterns environmentally adapted offspring phenotypes. Here, we investigated (DNA methylation/hydroxymethylation) gene expression across gametogenesis embryogenesis stickleback (Gasterosteus aculeatus) under three ocean warming scenarios (ambient, +1.5 +4°C). We found acclimation led dynamic temperature-sensitive throughout development. Both global methylation/hydroxymethylation genes involved modifications were strongly differentially affected by increased scenarios. Comparing transcriptomic profiles gonads, mature gametes embryonic stages showed sex-specific accumulation temperature sensitivity several actors. methyltransferase induction was primarily maternally inherited (suggesting maternal control remethylation), histone-modifying enzymes shaped parents. Importantly, massive, temperature-specific changes landscape occurred blastula, critical stage for successful development, which could, thus, translate substantial consequences phenotype resilience In summary, study identified regulation, reflecting potential 'windows opportunity' adaptive responses future change.

Transposable elements (TEs) occupy nearly 40% of mammalian genomes and, whilst most are fragmentary and no longer capable transposition, they can nevertheless contribute to cell function. TEs within genes transcribed by RNA polymerase II be copied as parts primary transcripts; however, their full contribution mature transcript sequences remains unresolved. Here, using long short read (LR SR) sequencing data, we show that 26% coding 65% noncoding transcripts in human pluripotent stem cells (hPSCs) contain TE-derived sequences. Different TE families incorporated into RNAs unique patterns, with consequences structure The presence a is correlated TE-type specific changes its subcellular distribution, alterations steady-state levels half-life, differential association Binding Proteins (RBPs). We identify hPSC-specific incorporation endogenous retroviruses (ERVs) LINE:L1 protein-coding mRNAs, which generate sequence-derived peptides. Finally, single RNA-seq reveals hPSCs express ERV-containing transcripts, differentiating subpopulations lack ERVs SINE LINE-containing transcripts. Overall, our comprehensive analysis demonstrates the more widespread has greater impact than previously appreciated.

Germline epigenetic programming, including genomic imprinting, substantially influences offspring development. Polycomb Repressive Complex 2 (PRC2) plays an important role in Histone 3 Lysine 27 trimethylation (H3K27me3)-dependent loss of which leads to growth and developmental changes mouse offspring. In this study, we show that from oocytes lacking the PRC2 protein Embryonic Ectoderm Development (EED) were initially developmentally delayed, characterised by low blastocyst cell counts substantial delay mid-gestation embryos. This initial was resolved as underwent accelerated fetal development late gestation resulting similar stage weight controls at birth. The Eed -null associated with remodelling placenta, involved increase maternal tissue size, conspicuous expansion glycogen-enriched population, delayed parturition. Despite placental development, efficiency, blood glucose levels low, metabolome unchanged. Moreover, while expression H3K27me3-imprinted gene amino acid transporter Slc38a4 increased, individual acids controls, indicating transport not enhanced. Genome-wide analyses identified extensive transcriptional dysregulation DNA methylation affected placentas, a range imprinted non-imprinted genes.

Somatic embryogenesis (SE), which is a process that involves the in vitro-induced embryogenic reprogramming of plant somatic cells, requires dynamic changes cell transcriptome. These are fine-tuned by many genetic and epigenetic factors, including posttranslational histone modifications such as acetylation. Antagonistically acting enzymes, acetyltransferases (HATs) deacetylases (HDACs), control acetylation developmental processes, believed to SE. However, function specific HAT/HDACs genes subjected acetylation-mediated regulation during SE have yet be revealed.
