  1. 1. Olfactory genomics of bark- and ambrosia beetles : Evolution and function of chemoreceptors

    Författare :Twinkle Biswas; Feromongruppen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Curculionidae; functional characterisation; odorant receptors ORs ; gustatory receptors; ionotropic receptors; orthologues; paralogues; olfactory sensory neurons; OR-ligand interaction;

    Sammanfattning : Insect behaviours, such as host and mate selection, are often mediated by chemical cues. The chemical cuesare detected by large and rapidly evolving families of chemoreceptors which include odorant receptors (ORs),gustatory receptors (GRs) and ionotropic receptors (IRs). LÄS MER

  2. 2. Effects of retinoic acid in the mouse olfactory sensory systems

    Författare :Maria Hörnberg; Staffan Bohm; Finn Hallböök; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory; retinoic acid; neuron survival; Molecular biology; Molekylärbiologi;

    Sammanfattning : A common characteristic in neurodegenerative diseases of the brain is death of specific neuronal populations. The lack of neuron proliferation and axon extension in most parts of the central nervous system leads to chronic loss of neurons in the case of injury or disease. LÄS MER

  3. 3. From sequence to function : Comparative studies of insect olfactory receptors

    Författare :Xiaoqing Hou; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Olfactory receptor; Heterologous expression; Pheromone; Plant volatile; Insect;

    Sammanfattning : In insects airborne odors are detected by the odorant receptors (ORs) and ionotropic receptors (IRs), located on the dendritic membrane of the olfactory sensory neurons (OSNs) housed in olfactory sensilla. The OR and IR gene families show high plasticity in lineage expansion and contraction following the birth-and-death evolutionary model. LÄS MER

  4. 4. Molecular and functional anatomy of the mouse olfactory epithelium

    Författare :Viktoria Vedin; Anna Berghard; Urban Lendahl; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory epithelium; odorant receptor; zone; odorant; gene expression; cell specification; c-Fos; dichlobenil; olfactometry; proliferation; Molecular biology; Molekylärbiologi;

    Sammanfattning : The olfactory system is important for social behaviors, feeding and avoiding predators. Detection of odorous molecules is made by odorant receptors on specialized sensory neurons in the olfactory epithelial sheet. LÄS MER

  5. 5. 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
