  2. 11. Rates and patterns of genome evolution in Lepidoptera

    Author : Karin Näsvall; Niclas Backström; Simon Martin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromosomal rearrangements; karyotype evolution; recombination rate; Lepidoptera; genome structure; molecular evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : The evolutionary consequences of genome restructuring and chromosomal rearrangements can be significant, but the underlying mechanisms are poorly understood. This thesis explores the relationships between genome restructuring, recombination, and maintenance of genetic diversity in different butterfly species. READ MORE

  4. 12. Birds as a Model for Comparative Genomic Studies

    Author : Axel Künstner; Hans Ellegren; Hanna Johannesson; Chris Ponting; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Birds; Selection; Gene expression; Sequence evolution; Next-generation sequencing; Comparative genomics; Molecular evolution; Genomics; Substitution Rates; Non-coding DNA; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Comparative genomics provides a tool to investigate large biological datasets, i.e. genomic datasets. In my thesis I focused on inferring patterns of selection in coding and non-coding regions of avian genomes. READ MORE

  5. 13. Multi-omics investigation into bacterial evolution

    Author : Karl Dyrhage; Siv Andersson; Dan I. Andersson; Jay Hinton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; bacterial evolution; cellular complexity; comparative genomics; transcriptomics; proteomics; fructophilic lactic acid bacteria; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : The focus of this thesis is the investigation of the evolution and cellular processes of Tuwongella immobilis and Apilactobacillus kunkeei, two bacterial species with different levels of genomic and cellular complexity, using a multi-omics approach.In the first study we examined the proteome of T.

  6. 14. Rates and patterns of molecular evolution in avian genomes

    Author : Paulina Bolívar; Hans Ellegren; Carina F. Mugal; Mikkel Heide Schierup; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; recombination; GC-biased gene conversion; Hill-Robertson interference; effective population size; dN dS; distribution of fitness effects; avian genomes; collared flycatcher; sex chromosomes; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Evolution is the change in inherited characteristics of a population through subsequent generations. The interplay of several evolutionary mechanisms determines the rate at which this change occurs. READ MORE

  7. 15. Ribosomal RNA Modification Enzymes : Structural and functional studies of two methyltransferases for 23S rRNA modification in Escherichia coli

    Author : Avinash S. Punekar; Maria Selmer; Martino Bolognesi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; ribosome biogenesis; ribosome assembly; ribosomal RNA; peptidyltransferase center; domain V; post-transcriptional modification; methyltransferases; S-adenosyl-methionine; RlmM; Cm2498; RlmJ; m6A2030; X-ray crystallography; substrate recognition; substrate specificity; catalytic mechanism; evolution; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biokemi; Biochemistry;

    Abstract : Escherichia coli ribosomal RNA (rRNA) is post-transcriptionally modified by site-specific enzymes. The role of most modifications is not known and little is known about how these enzymes recognize their target substrates. READ MORE
