  2. 1. HDZip I Transcription Factors in Arabidopsis thaliana : Expression and Function in Relation to Environmental Stress Conditions

    Author : Anna S. B. Olsson; Peter Engström; Eva Söderman; Pieter B. F. Ouwerkerk; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; homeodomain leucine zipper; ABA; transcription factor; water deficit; Arabidopsis thaliana; Biologi; Biology; Biologi;

    Abstract : The homeodomain leucine zipper (HDZip) proteins constitute a plant-specific family of transcription factors, that based on sequence criteria have been grouped into four classes, HDZip I-IV. This thesis describes the phylogeny, function, expression patterns and regulation of the HDZip class I genes in the model species Arabidopsis thaliana. READ MORE

  4. 2. Approaches to Species Delineation in Anamorphic (mitosporic) Fungi : A Study on Two Extreme Cases

    Author : Olga Vinnere; Siv Andersson; Jamshid Fatehi; Berndt Gerhardson; Stephen B. Goodwin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; fungal taxonomy; Colletotrichum acutatum; Mycelia Sterilia; Phoma; Campanella; phylogeny; species concept in fungi; Biologi; Biology; Biologi;

    Abstract : Since the beginning of mycology, studies of species concept in fungi have been mainly based on morphology, partially due to the history of mycology as part of botany. Current advances in biochemical and molecular research have provided mycologists with powerful tools that can be used for delineation of fungal taxa. READ MORE

  5. 3. Cellular receptors for species B adenoviruses

    Author : Marko Marttila; Niklas Arnberg; Göran Wadell; Tomas Bergström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; CD46; CD80; CD86; Species B; Receptor; Internalization; Infection; Tropism; Virology; Virologi;

    Abstract : Adenoviruses belong to the most common human pathogens. The severity of infection varies greatly, from subclinical to lethal, depending on the virus type and immune status of the infected host. The 51 known human adenovirus serotypes are divided into six species (A-F) based on characteristics such as tropism. READ MORE

  6. 4. Trophic interactions and behaviour : Studies relevant to a Baltic Sea biomanipulation

    Author : Per B. Holliland; Sture Hansson; Elena Gorokhova; Peter Tiselius; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zooplankton; non-indigenous species; selectivity; food web; rearing environment; fish stocking; Sander lucioperca; diel vertical migration; ontogeny; ovigerous; Marine Ecology; marin ekologi;

    Abstract : The main theme of this thesis is the interactions of animals with the environment and each other. The thesis was written within the framework of a biomanipulation project “Pikeperch in Himmerfjärden”. READ MORE

  7. 5. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations

    Author : Mårten B. Hjernquist; Lars Gustafsson; Marcel Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary ecology; competition; sex allocation; paternity; EPP; inadvertent social information; migration; breeding density; territory quality; territory availability; great tit; blue tit; Ficedula albicollis; Biology; Biologi; Animal Ecology; zooekologi;

    Abstract : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. READ MORE
