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

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

   Sammanfattning : 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. 2. Molecular biology of barnacle Balanus improvisus settlement

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

   Författare :Matthew Lukenge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : 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.
