1. 1. Comparative Genomics of Endosymbiotic Bacteria

   Författare :Ivica Tamas; Paul Baumann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; comparative genomics; endosymbiotic bacteria; Buchnera; reductive evolution; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : Genomes of intracellular bacteria are thought to be the products of reductive evolution. They have evolved from ancestral genomes of free-living bacteria through a process of massive gene loss. LÄS MER

3. 2. Evolutionary Processes and Genome Dynamics in Host-Adapted Bacteria

   Författare :Björn Nystedt; Siv Andersson; David Guttman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; pathogen; secretion system; Bartonella; Buchnera; Blochmannia; Helicobacter; Bioinformatics; Bioinformatik; Evolutionary Genetics; evolutionär genetik;

   Sammanfattning : Many bacteria live in close association with other organisms such as plants and animals, with important implications for both health and disease. This thesis investigates bacteria that are well adapted to live inside an animal host, and describes the molecular evolutionary processes underlying host-adaptation, based on bacterial genome comparisons.

4. 3. Genome Evolution in Maternally Inherited Insect Endosymbionts

   Författare :Lisa Klasson; Siv Andersson; Jonas Sandström; George Weinstock; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi;

   Sammanfattning : Symbiosis is a widely common phenomenon in nature and has undoubtedly contributed to the evolution of all organisms on earth. Symbiotic associations can be of varying character, such as parasitic or mutualistic, but all imply a close relationship. LÄS MER

5. 4. In silico Studies of Early Eukaryotic Evolution

   Författare :Björn Canbäck; Martin Embley; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : A question of great interest in evolutionary biology is how and why the eukaryotic cell evolved. Several hypotheses have been proposed, ranging from an early emergence of a primitive eukaryotic cell, to various fusion models like the hydrogen hypothesis. Within this context, relevant bacterial gene families and genomes are examined in this thesis. LÄS MER
