2. 1. Cell wall biosynthesis in the pathogenic oomycete Saprolegnia parasitica

   Author : Elzbieta Rzeszutek; Vincent Bulone; Carol Munro; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose biosynthesis; chitin biosynthesis; cellulose synthase genes; chitin synthase genes; oomycetes; Saprolegnia parasitica; Biotechnology; Bioteknologi;

   Abstract : The oomycete Saprolegnia parasitica is a fungus-like microorganism responsible for the fish disease saprolegniosis, which leads to important economic losses in aquaculture. Currently, there is no efficient method to control the infection and therefore methods for disease management are urgently needed. READ MORE

4. 2. Differentiation and Pathogenicity within the Saprolegniaceae : Studies on Physiology and Gene Expression Patterns in Saprolegnia parasitica and Aphanomyces astaci

   Author : Gunnar Andersson; Michael J. Bidochka; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Zoofysiologi; Animal physiology; Zoofysiologi; fysiologisk mykologi; Physiological Mycology;

   Abstract : Saprolegnia parasitica and Aphanomyces astaci are parasitic water moulds belonging to the Oomycetes. Despite their importance as parasites they are very little studied at the molecular level and the work described in this thesis was aimed at increasing the molecular knowledge of these organisms by cloning and characterising genes of potential importance for reproduction and pathogenicity.

5. 3. Analysis of sterol metabolism in the pathogenic oomycetes Saprolegnia parasitica and Phytophthora infestans

   Author : Paul Dahlin; Vincent Bulone; Lisbeth Jonsson; Katharina Pawlowski; Lauren Mckee; Sophia Ekengren; Folke Sitbon; Steven Kelly; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

   Abstract : The primary objective of this thesis was to investigate the sterol metabolism of two pathogenic oomycetes, specifically the processes of sterol synthesis and sterol acquisition in the fish pathogen Saprolegnia parasitica (Saprolegniales) and the plant pathogen Phytophthora infestans (Peronosporales). Furthermore, the effects of steroidal glycoalkaloids from Solanaceous plants, on P. READ MORE

6. 4. Characterization of specific domains of the cellulose and chitin synthases from pathogenic oomycetes

   Author : Christian Brown; Vincent Bulone; Carol Munro; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose biosynthesis; chitin biosynthesis; cellulose synthase genes; chitin synthase genes; oomycetes; Saprolegnia monoica; Microtubule Interacting and Trafficking MIT domain; Pleckstrin Homology PH domain; Biotechnology; Bioteknologi;

   Abstract : Some oomycetes species are severe pathogens of fish or crops. As such, they are responsible for important losses in the aquaculture industry as well as in agriculture. Saprolegnia parasitica is a major concern in aquaculture as there is currently no method available for controlling the diseases caused by this microorganism. READ MORE

7. 5. Identification and characterisation of chitin and cellulose synthases in oomycetes : New tools for biochemical studies and structure determination

   Abstract : Despite resembling ‘true’ fungi in terms of morphological features, oo­mycetes form a distinct eukaryotic lineage of filamentous microorganisms that belongs to the stramenopiles, a group of protists also comprising the closely-related brown algae and diatoms. Many oomycetes are devastating pathogens of plants and animals, globally causing significant economic los­ses in the agriculture and aquaculture industries, and posing considerable environmental damage to natural ecosystems.
