  1. 1. 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

  3. 2. Plants as Factories for Insect Pheromone Production : Deciphering and Reconstructing Sex Pheromone Biosynthetic Pathways of Female Moths

    Författare :Yihan Xia; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pheromones biosynthesis; desaturases; elongases; reductases; plant factories;

    Sammanfattning : Compared to other organisms in which the fatty acyl desaturases (FADs) are mostly involved in normal cellular lipid metabolism, moth FADs have evolved extent functions in the biosynthesis of sex pheromones. Female moths releasespecies-specific sex pheromones to attract conspecific males over a long distance for mating. LÄS MER

  4. 3. Pheromone production in the butterfly Pieris napi L

    Författare :Rushana Murtazina; Raimondas Mozuraitis; Joop van Loon; KTH; []
    Nyckelord :Pieris; Lepidoptera; pheromone; aphrodisiaca; antiaphrodisiaca; biosynthesis; flower volatiles; stable isotopes; incorporation; neral; geranial; methyl salicylate; benzyl cyanide; L - phenylalanine;

    Sammanfattning : Aphrodisiac and anti-aphrodisiac pheromone production and composition in the green-veined white butterfly Pieris napi L. were investigated.Aphrodisiac pheromone biosynthesis had different time constraints in butterflies from the diapausing and directly developing generations.

  5. 4. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

    Författare :Åsa Hagström; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

    Sammanfattning : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.

  7. 5. Evolution of mate signalling in moths: Biosynthetic gene families and diversification of female sex pheromones

    Författare :Marjorie Liénard; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; duplication; transcriptome; fatty-acyl-CoA reductase; fatty-acyl-CoA desaturase; fatty-acid biosynthesis; odour; insect; Lepidoptera; phylogeny; qPCR; heterologous expression; mutagenesis;

    Sammanfattning : Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. LÄS MER
