Advanced Science, EarlyView.The authors complement bovine pan‐SV with massive novel structural variations (SVs) identified through long‐read sequencing of 83 globally distributed cattle breeds. Repetitive sequence‐mediated SVs (rep‐SV) exhibit distinct dynamic patterns throughout cattle sub‐speciation and/or domestication processes, including uneven distribution between chr‐X and

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos
Advanced Science, EarlyView.Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

A CRISPR-Cas9 sex-ratio distortion system for genetic control. [PDF]
, 2016 Genetic control aims to reduce the ability of insect pest populations to cause harm via the release of modified insects. One strategy is to bias the reproductive sex ratio towards males so that a population decreases in size or is eliminated altogether ...

Oestrogens and spermatogenesis [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2010 The role of oestrogens in male reproductive tract physiology has for a long time been a subject of debate. The testis produces significant amounts of oestrogenic hormones, via aromatase, and oestrogen receptors (ERs)α (ESR1) and ERβ (ESR2) are selectively expressed in cells of the testis as well as the epididymal epithelium, depending upon species ...

Advanced Science, EarlyView.The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Interpreting the dependence of mutation rates on age and time [PDF]
, 2015 Mutations can arise from the chance misincorporation of nucleotides during DNA replication or from DNA lesions that are not repaired correctly. We introduce a model that relates the source of mutations to their accumulation with cell divisions, providing
