Choline is a vital micronutrient that can be utilized in the formation of betaine and multiple phospholipids. In this study, we aimed to confirm, expand on previous findings, how choline impacts embryos from first 7 days development affect postnatal phenotype. Bos indicus were cultured choline-free medium (termed vehicle) or supplemented with 1.8 mM Blastocyst-stage transferred into crossbred recipients. Once born, calves evaluated at birth, 94 d, 178 d weaning (average age = 239 d)....
Abstract Interspecies hybrids often show some advantages over parents but also frequently suffer from reduced fertility, which can sometimes be overcome through sexual reproduction that sorts out genetic incompatibilities. Sex is however inefficient due to the low viability or fertility of hybrid offspring and thus limits their evolutionary potential. Mitotic cell division could an alternative recovery in species such as fungi propagate asexually. Here, test this, we evolve parallel under...
About 15,000 angiosperm species (∼6%) have separate sexes, a phenomenon known as dioecy. Why dioecious taxa are so rare is still an open question. Early work reported lower richness in compared with nondioecious sister clades, raising the hypothesis that dioecy may be evolutionary dead-end. This has been recently challenged by macroevolutionary analyses detected no or even positive effect of on diversification. However, possible genetic consequences at population level, which could drive...
In the last decade, progress has been made in methods to identify sex determination system plants. This gives opportunity study chromosomes that arose independently at different phylogenetic scales, and thus allows discovery understanding of early stages chromosome evolution. genus Silene, have evolved least two clades from a nondioecious ancestor, Melandrium Otites sections. latter, could be younger than section Melandrium, based on studies as no heteromorphic detected. might also exhibit...
Abstract Infertility and post-partum reproductive diseases are significant challenges in cattle farming, with the maternal immune system’s ability to recognize tolerate embryo being crucial for successful gestation. DNA methylation hematopoietic cells may influence susceptibility fertility issues, making identification of epigenetic changes vital sustainable animal production. This study aimed characterize methylome relation fertility, potentially enabling early detection subfertility. Using...
Reproductive isolation can rise either as a consequence of genomic divergence in allopatry or byproduct divergent selection parapatry. To determine whether reproductive gynodioecious Silene nutans results from allopatric ecological adaptation following secondary contact, we investigated the pattern postzygotic and hybridization natural populations using two phylogeographic lineages, western (W1) eastern (E1). Experimental crosses between lineages identified strong, asymmetric W1 E1...
Manipulative parasites are thought to liberate molecules in their external environment, acting as manipulation factors with biological functions implicated host's physiological and behavioural alterations. These part of a complex mixture called the secretome. While secretomes various have been described, there is very little data for putative manipulative parasite. It necessary study molecular interaction between parasite its host better understand how such alterations evolve.Here, we used...

Abstract Historical demographic processes and mating systems are believed to be major factors in the shaping of intraspecies genetic diversity plants. Among Caryophyllales, Beta section genus Beta, within Amaranthaceae/Chenopodiaceae alliance, is an interesting study model with species subspecies ( macrocarpa , patula vulgaris maritima B.v. adanensis) differing geographical distribution system. In addition, one species, B. mainly diploid, varies its level ploidy a tetraploid cytotype...
This study characterized variations in the methylation profile of mitochondrial DNA (mtDNA) during initial bovine embryo development and correlated presence with mtDNA transcription. Bovine oocytes were obtained from abattoir ovaries submitted to vitro culture procedures. Oocytes embryos collected at various stages (immature oocyte, IM; mature MII; zygote, ZY; 4-cells, 4C; 16-cells, 16C blastocysts, BL). Total (including mtDNA) was used for Whole Genome Enzymatic Methyl Sequencing...
The current decline in dairy cattle fertility has resulted significant financial losses for farmers. In the past, most efforts to improve have been focused on either management or genetics, while epigenetics received less attention. this study, 12 bulls were selected from a provided 100 bull list and studied (High daughter = 6, Low 6) Enzymatic methylation sequencing Illumina HiSeq platform according Canadian index (DFI), sires with high low average DFI of 92 112.6, respectively. And shows...
Abstract While the use of barcoded collections laboratory microorganisms and development barcode‐based cell tracking are rapidly developing in genetics genomics research, tools to track natural populations still lacking. The yeast Saccharomyces paradoxus is an emergent microbial model ecology evolution. More than five allopatric sympatric lineages have been identified hundreds strains isolated for this species, allowing assess impact diversity on complex traits. We constructed a collection...
The site of Narbons (township Montesquieu-de-Laurageais, Haute-Garonne), identified as a medieval area was excavated in August 1999 the setting preventive excavations carried out by AFAN on tracing A 66 freeway. Therefore, six pits are attributed to Neolithic and four them were containing burials. These burials set holes great depth, whose sections principally oblong or sub-rectangular. It appears that these structures might be some well reused graves because none skeleton contact with...

Abstract About 15,000 angiosperm species (∼6%) have separate sexes, a phenomenon known as dioecy. Early work reported lower richness in dioecious compared to non-dioecious sister clades, which was taken suggest that dioecy might be an evolutionary dead end. More recently, phylogenetic analyses using different methodologies challenged this conclusion. Here, we used population genomics approach look for evidence of handicaps the Silene genus at molecular level. We obtained RNA-seq data...
The Mesolithic site located in the western entrance of cave Les Fieux (Miers, Lot), excavated 1970's by F. Champagne, has often been interpreted as a hunting camp. This hypothesis is mostly based on features lithic industry, which largely dominated weapon elements. results multidisciplinary study assemblages now provide an opportunity to question validity this hypothesis. While data collected (in fields anthracology, zooarchaeology, carpology, technology and usewear, bone technology,...
