  2. 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; 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).

  4. 2. Molecular biology of barnacle Balanus improvisus settlement

    Author : Anna Abramova; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; barnacles; settlement; transcriptomics; ecdysone cascade; chemosensory receptors; waterborne pheromones;

    Abstract : The aim of this thesis was to investigate molecular mechanisms of various aspects of barnacle settlement, using the acorn barnacle Balanus improvisus. This barnacle is a common fouling species and a model organism for studies in settlement biology, in particular in relation to antifouling research. READ MORE

  5. 3. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

    Author : Jean-Marc Lassance; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biosynthetic enzymes; evolution; Ostrinia nubilalis; mate choice; mate finding; olfaction; biosynthesis; speciation; moth; pheromone; olfactory receptors.;

    Abstract : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. READ MORE

  6. 4. 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

  7. 5. Phagostimulatory dynamics of adenine nucleotides in mosquitoes : advancing a taste-based delivery method for vector control agents

    Author : Matthew Lukenge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The mosquitoes Aedes aegypti and Anopheles gambiae are vectors of major medical importance, incriminated in over half a million lives lost annually. While there has been significant focus on understanding the olfaction mechanisms underlying host-seeking in mosquitoes for the development of odour-based control tools, little is known about the mechanisms underlying gustation in blood feeding, the ultimate behaviour in the change of events leading up to disease transmission.
