1. 11. Comparative Genomics of Obligate and Facultative Intracellular Parasites

   Författare :Cecilia Alsmark; Russell Regnery; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : The α-proteobacteria Rickettsia prowazekii and Bartonella henselae are the causative agents of epidemic typhus and cat scratch disease respectively. Whereas R. prowazekii is an obligate intracellular parasite, B. henselae can live and proliferate both outside and inside the eukaryotic host cell. LÄS MER

3. 12. Biology of a small RNA virus that infects Drosophila melanogaster

   Författare :Sajna Anand Sadanandan; Dan Hultmark; Francis Jiggins; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nora virus; Drosophila melanogaster; virus biology; host-pathogen interaction; molekylärbiologi; Molecular Biology;

   Sammanfattning : Drosophila melanogaster has been extensively used as a model organism to study diverse facets of biology, including host-pathogen interactions and the basic biology of its pathogens. I have used the fruit fly as a model to study elementary aspects of Nora virus biology, such as the role of the different proteins encoded by the virus genome. LÄS MER

4. 13. Comparative Genomics in Diplomonads : Lifestyle Variations Revealed at Genetic Level

   Författare :Feifei Xu; Jan O. Andersson; Staffan G. Svärd; Matt Berriman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; comparative genomics; Giardia intestinalis; Spironucleus salmonicida; Trepomonas; diplomonad; intestinal parasite; free-living; sexual recombination; hydrogenosome; horizontal gene transfer; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

   Sammanfattning : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. LÄS MER

5. 14. Studies of the Carbon and Energy Metabolism in the Moss Physcomitrella patens

   Författare :Anders Nilsson; Hans Ronne; Leszek Kleczkowski; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hexokinase; SnRK1; sugar signaling; carbon metabolism; Physcomitrella patens; shuttle vector; subcellular localization; model organism; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

   Sammanfattning : Since a proper balance between anabolic and catabolic reactions is essential for all eukaryotes, the basic mechanisms for regulation of the energy and carbon metabolism have been conserved throughout evolution. The moss Physcomitrella patens, which belongs to one of the basal clades among land plants, has many unique properties that make it an excellent plant model system. LÄS MER

7. 15. Ancient roles of non-coding RNAs in eukaryotic evolution : contributions from social amoebae and other protists

   Författare :Lotta Avesson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : RNAs not coding for proteins, non-coding RNAs (ncRNAs) have many important roles in all kingdoms of life. Especially in eukaryotes, the regulatory functions of ncRNAs have been suggested as a major force in the evolution of complex traits. LÄS MER
