  2. 1. Mapping the Golgi retention signal in the G1 membrane glycoprotein of Uukuniemi virus, a member of the Bunyaviridae family

    Author : Agneta M Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Golgi complex; retention signal; protein transport; virus membrane glycoproteins; virus budding; Uukuniemi virus; Phlebovirus; Bunyaviridae;

    Abstract : Newly synthesized secretory and integral membrane proteins destined for the plasma membrane are transported along the exocytic pathway from the endoplasmic reticulum (ER) via the Golgi complex (GC) to the cell surface. Some of the transported proteins contain information, which target them to their correct intracellular locations. READ MORE

  4. 2. Food web structures and carbon transfer efficiencies in a brackish water ecosystem

    Author : Kristin Dahlgren; Ulf Båmstedt; Agneta Andersson; Marja Koski; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon transfer efficiency; Food web efficiency; zooplankton; production; pelagic; benthic; fatty acids; wax esters; Marine ecology; Marin ekologi;

    Abstract : Two differently structured food webs can be distinguished in the pelagic habitat of aquatic systems; the classical one (autotrophic) with phytoplankton as a base and the microbial food web (heterotrophic) with bacteria as a base. Energy (produced at the basal trophic level) reaches higher trophic levels, i.e. READ MORE

  5. 3. Molecular evidence for metazooplankton feeding on filamentous cyanobacteria and picocyanobacteria in the Baltic Sea

    Author : Nisha Motwani; Elena Gorokhova; Agneta Andersson; Jakob Walve; Karolina Ininbergs; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marin ekologi; Marine Ecology;

    Abstract : Interactions between zooplankton and cyanobacteria are complex and system-specific. They play an important role in mediating responses of phytoplankton to changes in nutrient regime and top-down manipulations. READ MORE

  6. 4. Significance of N2 fixing planktonic symbioses for open ocean ecosystems

    Author : Marcus Stenegren; Rachel A. Foster; Agneta Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen fixation; diazotrophs; symbiosis; DDA; cyanobacteria; qPCR; piecewise SEM; microarray; tropics; subtropics; marine; open ocean; Richelia; Calothrix; Marine Ecology; marin ekologi;

    Abstract : Di-nitrogen (N2) fixers, also called diazotrophs, are able to reduce atmospheric N2 into bioavailable nitrogen, giving them an advantage in open ocean regions with low dissolved inorganic nitrogen concentrations. The focus of this thesis are three lineages of symbiotic heterocystous filamentous types (het-1, het-2 and het-3), that associate with several genera of microalgae called diatoms (collectively referred to as Diatom Diazotroph Associations, DDAs).
