Project description:Breeding schemes for meat production in rabbits involved a three-way cross of specialized lines in which a paternal line inseminates maternal crossbred females. Paternal line or terminal sire are selected for growth traits, being the males used for the production of fertile dose at the insemination centres and farms. So high growth rate males must produce, in addition, semen in sufficient quantity and quality to meet the demand of insemination and, nevertheless, several studies have been showed that selection for growth have effects on reproduction performance in female and males. In rabbits, negative effects has been observed in ovulation induction, prenatal survival and genetic correlation to fertility. Many factors influence the production and quality of rabbit semen, management as collection frequency, environment (season or photoperiod, nutrition and genetic. Most of the previous studies have been focused in the effects of selection on the seminal and sperm parameters but, little attention has been paid to the protein seminal plasma or sperm composition and if these changes could be affect the fertility of seminal doses obtained from the paternal males. The aim of this study was to evaluate if selection program by daily gain in fattening period has changed seminal traits, plasma and sperm proteoma and, the fertility of semen when it is used in artificial insemination. To do this we uses two re-derived groups of paternal males obtained from vitrified embryos with a difference of 18 generations between both groups.

Project description:Development of the early embryo is thought to be mainly driven by maternal gene products and post-transcriptional gene regulation. Here, we used metabolic labeling to show that RNA can be transferred by sperm into the embryo. To identify genes with paternal expression in the embryo, we performed crosses of males and females from divergent C. elegans strains. RNA sequencing of mRNAs and small RNAs in the 1-cell hybrid embryo revealed that about two hundred paternal mRNAs are reproducibly expressed in the embryo, and that about half of assayed endogenous siRNAs and piRNAs are also of paternal origin. Together, our results suggest an unexplored paternal contribution to early development. To reveal the identity of paternal RNA molecules, we performed a cross of males and females from two divergent C. elegans strains because we reasoned that sequencing of embryonic RNA and SNP analysis should then identify and quantify maternal and paternal transcripts. These sequencing experiments were carried out in purified hybrid 1-cell embryos and comprised small RNAs and mRNAs. For comparison we sequenced mRNAs and small RNAs from the parental strains: paternal (Hawaiian males, CB4856) and maternal (fem-1(hc17ts)/TX189(OMA-1::GFP). For the annotation of strain specific mutations (SNPs) we sequenced mRNA and small RNAs extracted from whole worms. All experiments were performed in at least two independent biological replicates.

Project description:Epidemiological studies suggest that a father’s diet can influence offspring health. A proposed mechanism for paternal transmission of environmental information is via the sperm epigenome. The epigenome includes heritable information such as DNA methylation. We hypothesized that the dietary supply of methyl donors would alter epigenetic reprogramming in sperm. This hypothesis was examined by feeding male mice a folate deficient (FD) and folate sufficient (FS) diets and then generating and analyzing DNA methylation profiles of their sperm. C57BL/6 males were fed either the FS or FD diet throughout life (FS, n=32; FD, n=35; 2-3 month old). Pooled gene promoter DNA methylation profiles were generated from the sperm of three FS males and four FD males using the method of MeDIP (Methylated DNA Immunoprecipitation) followed by microarray hybridization.

Project description:Honeybee semen was collected by gently squeezing the male abdomens. Samples were pooled and then centrifuged. Pelleted sperm was collected and analysed with both 2D PAGE and gel-free methods. For the 2D PAGE, protein spots were digested using trypsin. Extracted peptides, resolved on a C18 column, were analysed by an Agilent LC/MSD Trap XCT Ultra 6330 mass spectrometer. Spectra were searched against the honeybee protein sequences (RefSeq release 48) using Mascot algorithm (with 1 missed cleavage, Cys-carbamidomethylation as fixed modification, and Met-oxidation and N/Q-deamidation as variable modifications). For the MudPit analysis the sperm sample was digested by trypsin. Peptides were resolved using strong cation exchange chromatography followed by reverse phase (C18) HPLC and finally analysed by an Agilent QTOF mass spectrometer. Resulting spectrum files were converted to mzXML and merged using ProteoWizard msconvert. These were then searched against honeybee protein sequences using Mascot, Omssa and X!tandem (all with 1 missed cleavage, and Met-oxidation and N/Q-deamidation as variable modifications). Results of the three search engines were pooled using TPP.

Project description:A major goal of molecular evolutionary biology is to understand the fate and consequences of duplicated genes. In this context, aphids are particularly intriguing because the newly sequenced pea aphid genome is characterized by extraordinarily high levels of lineage-specific gene duplication relative to other insect genomes. While analyzing the results of a microarray comparing gene expression between male, sexual female and asexual female Myzus persicae aphids, we unexpectedly found duplicated nutrient amino acid transporters highly upregulated in males. These transporters, homologous to the Drosophila slimfast, belong to an aphid-specific gene family expansion in which other paralogs are thought to have functionally diverged to fill a role in mediating interactions between aphids and their nutrititonally required bacterial symbiont. The lack of a known male role for slimfast in other insects suggests that aphid slimfast paralogs have been retained as a result of functional divergence to fill multiple novel functional roles in symbiosis and in males. Two biological replicates, four treatments (males, asexual females at long day, asexual females at short day, sexual females), dye flip
