  1. 1. 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

  3. 2. Regulators of chromatin and transcription in Drosophila

    Författare :Filip Crona; Mattias Mannervik; Fernando Azorin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcription; chromatin; co-regulators; CBP; lysine demethylase; KDM4A; Brakeless; Drosophila; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Development of multicellular organisms is achieved by organized temporal and spatial patterns of gene expression leading to cell differentiation. Chromatin regulators control how the DNA is utilized by altering access of proteins to DNA and thereby function as co-factors in transcription. LÄS MER

  4. 3. Midgut and muscle development in Drosophila melanogaster

    Författare :Margret Shirinian; Ruth Palmer; Anne Uve; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; visceral mesoderm; endoderm; somatic muscles; Alk; C3G; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The fully developed and functional Drosophila midgut comprises two layers, the visceral mesoderm and the endoderm. The visceral muscle of the midgut is formed by the fusion of founder cells with fusion competent cells to form the muscle syncytia. LÄS MER

  5. 4. Functions of Transcriptional Co-regulators in Drosophila development

    Författare :Tobias Lilja; Mattias Mannervik; Ze'ev Paroush; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcription; Co-regulator; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : During Drosophila development, regulation of gene expression through interplay between transcriptional activators and repressors is generating complex patterns of gene expression that leads to cell differentiation. For proper control of transcription, transcription factors bind to DNA at control regions, so called Cis Regulatory Modules (CRM). LÄS MER

  7. 5. Chromatin regulators and transcriptional control of Drosophila development

    Författare :Qi Dai; Mattias Mannervik; Albert J. Courey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatin; Co-factors; Transcription; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The development of a multicellular organism is programmed by complex patterns of gene expression. In eukaryotic cells, genes are packaged by histone proteins into chromatin. Chromatin regulators often function as transcription co-factors. LÄS MER
