  1. 1. Comparative genomics of the genus Mycobacterium : Genome evolution, phylogeny and diversity

    Författare :Phani Rama Krishna Behra; Leif Kirsebom; Bengt Persson; Mikael Rhen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mycobacterial genomes; core gene phylogeny; tRNA and non-coding RNA; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The genus Mycobacterium includes more than 190 species, and many cause severe diseases such as tuberculosis and leprosy. According to the "World Health Organization", in year 2019 alone, 10 million people developed TB, and 1.4 million died. LÄS MER

  3. 2. Evolution of mate signalling in moths: Biosynthetic gene families and diversification of female sex pheromones

    Författare :Marjorie Liénard; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; duplication; transcriptome; fatty-acyl-CoA reductase; fatty-acyl-CoA desaturase; fatty-acid biosynthesis; odour; insect; Lepidoptera; phylogeny; qPCR; heterologous expression; mutagenesis;

    Sammanfattning : Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. LÄS MER

  4. 3. Molecular systematics of the antbird-ovenbird complex (Aves: Furnariida)

    Författare :Martin Irestedt; Per G. P. Ericson; Richard O. Prum; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systematics phylogeny DNA antbird ovenbird; Biology; Biologi;

    Sammanfattning : This thesis concerns the phylogenetic relationships among suboscine birds with special emphasis on the antbird-ovenbird complex (Aves: Furnariida). The principal aim is to produce a framework for future systematic and comparative studies of suboscines by generating robust phylogenetic hypotheses from DNA-sequence data. LÄS MER

  5. 4. Inferring Ancestry : Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life

    Författare :Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Phylogeny; Phylogenomics; Mitochondria; Eukaryote tree of life; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. LÄS MER

  7. 5. Genome and transcriptome studies of the protozoan parasites Trypanosoma cruzi and Giardia intestinalis

    Författare :Oscar Franzén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Trypanosoma cruzi and Giardia intestinalis are two human pathogens and protozoan parasites responsible for the diseases Chagas disease and giardiasis, respectively. Both diseases cause su ering and illness in several million individuals. LÄS MER
