  1. 1. Drosophila Sensory Neuroethology

    Författare :Suzan Mansourian; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Vinegar Fly; olfactory system; hygrosensation; receptor; ancestral habitat;

    Sammanfattning : Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats.

  3. 2. Genomic and transcriptomic investigation of reproductive incompatibility in Drosophila

    Författare :Guilherme Costa Baião; Lisa Klasson; Alistair Darby; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wolbachia; Drosophila; Drosophila paulistorum; Differential Gene Expression; Reproductive Incompatibility; Reproductive Isolation; Comparative Genomics; Transcriptomics; RNA-Seq; Heteroplasmy; Mitochondria; Genomic conflict; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Both nuclear and cytoplasmic elements can contribute to the emergence of reproductive incompatibilities that influence evolution and speciation. In the projects that compose this thesis, we use genomics and transcriptomics to study some of those elements in Drosophila. LÄS MER

  4. 3. Peptidoglycan recognition proteins in Drosophila melanogaster

    Författare :Thomas Werner; Dan Hultmark; Bruno Lemaitre; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Drosophila; PGRP; peptidoglycan; pattern recognition; imd; Relish; isoform; RNAi; mbn-2; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The fruit fly Drosophila melanogaster is an excellent model organism to study the innate immune response, because insects and mammals share conserved features regarding the recognition and destruction of microorganisms and Drosophila is easily accessible to genetic manipulation. In my present study, I identified a new family of pattern recognition molecules for bacterial peptidoglycan in Drosophila, the Peptidoglycan Recognition Proteins (PGRP). LÄS MER

  5. 4. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors

    Författare :Lina E. Enell; Dick Nässel; Jonathan Bacon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insect nervous system; Drosophila; GABA; sNPF; GPCR; ion channel receptor; feeding; metabolic stress; olfaction; antennal; lobe; mushroom body; Morphology; Morfologi; funktionell morfologi; Functional Zoomorphology;

    Sammanfattning : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

  7. 5. Nucleoporins and Protein Transport in Drosophila

    Författare :Peggy Roth; Christos Samakovlis; Volker Cordes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NPC; Nucleoporin; Nup88; Nup214; CRM1; Dorsal; Drosophila; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Many biological responses rely on the selective translocation of transcriptional regulators in and out of the nucleus through nuclear pore complexes (NPC). More than one million macromolecules per minute pass through the NPC and an important challenge is to understand the coordination of nucleocytoplasmic trafficking. LÄS MER
