  2. 11. Evolution of sex chromosomes in Sylvioidea songbirds

    Author : Hanna Sigeman; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome; neo-sex chromosome; Birds; vertebrates; Genomics; Bioinformatics;

    Abstract : Sex chromosomes were discovered more than 100 years ago. They have been studied intensely from a theoretical perspective since then, giving rise to a large body of testable predictions about their evolution from autosomes. READ MORE

  4. 12. Genome dynamics and virulence in the human pathogen Candida glabrata

    Author : Khadija Mohamed Ahmad; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pathogenic yeast; Candida glabrata; small chromosomes; Genome rearrangement; Haploid and diploid yeast; RNA interference.;

    Abstract : Although the yeast Candida glabrata is considered to be a part of the commensal microflora in healthy individuals, during the last years it has been frequently isolated from patients with mucosal and systemic fungal infections. Now it is considered as the second most frequently isolated pathogenic yeast after Candida albicans. Despite its name, C. READ MORE

  5. 13. The genetic architecture of sexual dimorphism

    Author : Robert Griffin; Urban Friberg; Alexei Maklakov; Jon Ågren; Russell Bonduriansky; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; evolution; intralocus sexual conflict; sex chromosomes; sexually antagonistic selection; sexual dimorphism;

    Abstract : Phenotypic differences between the sexes evolve largely because selection favours a different complement of traits in either sex. Theory suggests that, despite its frequency, sexual dimorphism should be generally constrained from evolving because the sexes share much of their genome. READ MORE

  6. 14. The exploration and evolution of the avian genomic dark matter

    Author : Valentina Peona; Alexander Suh; Hanna Johannesson; Rachel O'Neill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genomics; genome assembly; sex chromosomes; birds; satellite DNA; transposable elements; endogenous retroviruses; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : The development and improvement of genome sequencing technologies in the last decade revolutionised the entire field of biology with genome assemblies of virtually any organism. Despite this tremendous progress, complex genomic regions are systematically missing from genome assemblies and form the so-called "genomic dark matter". READ MORE

  7. 15. Chromosome-specific adaptations of RNA stability and the roles of the roX RNAs in dosage compensation

    Author : Marie-Line Faucillion; Jan Larsson; Jean-Yves Roignant; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; dosage compensation; buffering; RNA stability; RNA decay; RNA half-life; RNA-seq; genome-wide; sex chromosomes; evolution; roX1; roX2; POF; MSL; molekylärbiologi; Molecular Biology;

    Abstract : Sex chromosomes evolved from an ancient pair of autosomes and the Y chromosome lost most of its genetic information in the process. This created two kinds of genomic imbalances: the first one between males (XY) and females (XX) and the second one between the sex chromosomes and the autosomes (X:AA). READ MORE
