  2. 1. Drivers of evolutionary change in Podospora anserina

    Author : Sandra Lorena Ament-Velásquez; Hanna Johannesson; Bengt Olle Bengtsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Podospora; Meiotic drive; Spore killing; vegetative incompatibility; heterokaryon incompatibility; allorecognition; speciation; Transposable elements; selfish genetic elements; fungi; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Genomic diversity is shaped by a myriad of forces acting in different directions. Some genes work in concert with the interests of the organism, often shaped by natural selection, while others follow their own interests. The latter genes are considered “selfish”, behaving either neutrally to the host, or causing it harm. READ MORE

  4. 2. Catching the Spore killers : Genomic conflict and genome evolution in Neurospora

    Author : Jesper Svedberg; Hanna Johannesson; Mark A. Kirkpatrick; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genomics; genomic conflict; genome evolution; meiotic drive; spore killer; suppression of recombination; inversions; fungi; Neurospora; Biologi; Biology;

    Abstract : A genome is shaped by many different forces. Recombination can for instance both create and maintain genetic diversity, but the need to locally reduce recombination rates will also leave specific signatures. READ MORE

  5. 3. The role of the cohesin loader in genome stability : a journey from yeast to human

    Author : Fosco Giordano; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Structural Maintenance of Chromosome (SMC) complexes, as their name suggests, have a central role in maintaining the higher structure of genomes, from bacteria to human, and in doing so protecting their integrity. Cohesin, one of three SMC complexes, is required to hold sister chromatids together until anaphase, and for homologous recombination-based DNA repair. READ MORE

  6. 4. Structural variants in the great tit genome and their effect on seasonal timing

    Author : Vinicius Henrique da Silva; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The biodiversity of our planet has been increasingly endangered by human actions. This nature biodiversity is strictly correlated with genomic diversity of all the species in the ecosystem. READ MORE
