  1. 6. Evolution of Vertebrate Endocrine and Neuronal Gene Families : Focus on Pituitary and Retina

    Författare :Daniel Ocampo Daza; Dan Larhammar; Marc Robinson-Rechavi; Uppsala universitet; []
    Nyckelord :phylogenetics; evolution; molecular evolution; gene family evolution; genome duplication; gene duplication; oxytocin receptor; vasopressin receptor; visual opsin; transducin; growth hormone; prolactin; somatolactin; growth hormone receptor; prolactin receptor; somatostatin receptor; SSTR; IGFBP; evolution; molekylär evolution; fylogeni;

    Sammanfattning : The duplication of genes followed by selection is perhaps the most prominent way in which molecular biological systems gain multiplicity, diversity and functional complexity in evolution. Whole genome duplications (WGDs) therefore have the potential of generating an extraordinary amount of evolutionary innovation. LÄS MER

  3. 7. Mitochondrial Evolution : Turning Bugs into Features

    Författare :Olof Karlberg; Siv Andersson; Michael Gray; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi;

    Sammanfattning : The bacterial origin of mitochondria from an ancient endosymbiosis is now widely accepted and the mitochondrial ancestor is generally believed to belong to the bacterial subdivision α-proteobacteria. The high fraction of mitochondrial proteins encoded in the nucleus has commonly been explained with a massive transfer of genes from the genome of the ancestral mitochondrion. LÄS MER

  4. 8. Genome evolution of a bee-associated bacterium

    Författare :Andrea García-Montaner; Siv Andersson; Matthias Horn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial evolution; Genomics; Symbiosis; Honeybees; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : The use of large-scale comparative genomics allows us to explore the genetic diversity and mechanisms of evolution of related organisms. This thesis has focused on the application of such approaches to study Lactobacillus kunkeei, a bacterial inhabitant of the honeybee gut.We produced 102 novel complete genomes from L. LÄS MER

  5. 9. Function and Evolution of Small Regulatory RNAs and their Associated Proteins : A Journey from Genome to Proteome

    Författare :Bart Edelbroek; Fredrik Söderbom; Jonathan R. Chubb; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microRNAs; non-coding RNAs; Evolution; Whole Genome Sequencing; Transcriptomics; Proteomics; small RNAseq; Amoebozoa; Multicellular development; Social amoebae; Comparative genomics; Genome annotation; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Organisms throughout the tree of life have evolved distinct ways to regulate gene expression. Some of these processes involve non-coding RNAs (ncRNAs), which are not translated but functional nonetheless. These ncRNAs are of utmost importance, with dysregulation of some causing severe developmental effects or even being lethal. LÄS MER

  7. 10. Dynamics of Microbial Genome Evolution

    Författare :Sean Hooper; Guy Perriére; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik; molekylärbiologi; Molecular Biology;

    Sammanfattning : The success of microbial life on Earth can be attributed not only to environmental factors, but also to the surprising hardiness, adaptability and flexibility of the microbes themselves. They are able to quickly adapt to new niches or circumstances through gene evolution and also by sheer strength of numbers, where statistics favor otherwise rare events. LÄS MER
