  1. 1. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology

    Author : Jothi Kumar Yuvaraj; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; pheromone receptors; olfaction; chemosensory; sensillum; HEK 293 cells;

    Abstract : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).

  2. 2. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus

    Author : Jun Chen; Martin Lascoux; Ulf Lagercrantz; Matt Olson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Speciation; Demographics; clinal variation; convergent evolution; transcriptome; small regulatory RNA; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.

  3. 3. Evolution of Lycopodiaceae (Lycopsida) : Relationships and Patterns of Diversification

    Author : Niklas Wikström; Anders Tehler; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; systematisk botanik; Systematic Botany;

    Abstract : A series of phylogenetic analyses using nucleotide sequence data resolves many aspects of the relationships in a group of land plants that until now have received comparatively little attention, the homosporous lycopsids or Lycopodiaceae. Although the group has evolved as an isolated lineage ever since the Late Devonian (more than 470 Myr ago), little is known about how modern species diversity relate to this ancient history.

  5. 5. Hematopoietic Serine Proteases from the Mast Cell Chymase and Tryptase Loci - a Functional and Evolutionary Analysis

    Author : Jenny Reimer; Lars Hellman; Gunnar Nilsson; Sara Wernersson; Göran Andersson; Uppsala universitet; []
    Keywords : Cell and molecular biology; immune system; mast cell; basophil; mast cell chymase locus; multigene tryptase locus; serine protease; evolution; Cell- och molekylärbiologi;

    Abstract : Mast cells are key effector cells in allergic and inflammatory diseases. However, their primary role is most likely in host defence against parasitic and bacterial infections. Mast cells are a particularly rich source of serine proteases. READ MORE
