  1. 1. Structure and Function of Odorant Binding Proteins and Chemosensory Proteins in Moths

    Author : Severine Jansen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR structure; Ecology; Ekologi; Development; Lepidoptera; Odorant Binding Proteins; Chemosensory Proteins;

    Abstract : Odorant Binding Proteins (OBPs) and Chemosensory Proteins (CSPs) are small soluble proteins found in the lymph of insect sensillae located on insect antennae. Odorant Binding proteins are implied in olfaction, by binding hydrophobic odorant molecules and transporting them to the olfactory receptor located on the dendrite of the olfactory neurons.

  2. 2. 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; 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).

  3. 3. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses

    Author : Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; GPCRs; G proteins; Sensory system; Signal transduction; Olfaction; Chemosensation; Hemichordates; Sponges; Porifera; Bilaterians; Holozoans; Fungi; Opisthokonts; Bioinformatics; Bioinformatik;

    Abstract : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. READ MORE

  4. 4. Pheromones, genes & transcriptomes. A molecular analysis of moth sex pheromone production

    Author : Maria Strandh; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Female moths emit sex pheromones to lure a mate. In this thesis I examined the transcriptomes of female moth pheromone glands in order to identify genes encoding proteins involved in pheromone production. Two cDNA-libraries were constructed from Agrotis segetum (Noctuidae) pheromone glands and the remaining body tissue, respectively. READ MORE

  5. 5. The control of growth and metabolism in Caenorhabditis elegans

    Author : Josefin Friberg; Simon Tuck; Cathy Savage-Dunn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TGFβ; insulin; collagen; p70 S6K; metabolism; growth; dauer; Caenorhabditis elegans; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The control of growth is a poorly understood aspect of animal development. This thesis focuses on body size regulation in Caenorhabditis elegans, and in particular, how worms grow to a certain size. In C. elegans, a key regulator of size is the TGFβ homologue DBL-1. READ MORE
