  1. 1. Parasite on Crayfish : Characterisation of Their Pathogenesis, Host Interactions and Diversity

    Författare :Eakaphun Bangyeekhun; Anders Tunlid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Crayfish; Parasite; Oomycete; Prophenoloxidase; Peroxinectin; Aphanomyces astaci; Psorospermium haecheli; White spot syndrome virus; Zoofysiologi; Animal physiology; Zoofysiologi; biologisk beroendeforskning; Biological Research on Drug Dependence;

    Sammanfattning : The crayfish plague refractory crayfish, Pacifastacus leniusculus, which can harbour the fungal parasite within melanotic sheath, are found to constitutively express the gene encoding for prophenoloxidase (proPO) after mimicking parasite attack. In contrast, the susceptible crayfish, Astacus astacus, responds to the parasite by increased levels of proPO transcript, particularly in the semigranular haemocytes. LÄS MER

  3. 2. Host-pathogen interactions in root infecting oomycete species

    Författare :Sara Hosseini; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The oomycetes include some of the most devastating pathogens on both cultivated crops and wild plants. In the genus Phytophthora some closely related species have a broad host range, while others are very host specific. LÄS MER

  4. 3. Cell wall biosynthesis in the pathogenic oomycete Saprolegnia parasitica

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

    Sammanfattning : 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. LÄS MER

  5. 4. Cellulose Biosynthesis in Oomycetes

    Författare :Johanna Fugelstad; Vincent Bulone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose biosynthesis; cellulose synthase genes; Oomycetes; Phytophthora infestans; Saprolegnia monoica.; Other bioengineering; Övrig bioteknik;

    Sammanfattning : Oomycetes have long been considered as a separate class within the kingdom Fungi, but they are in fact closer to brown algae. They are currently classified in the Stramenopile eukaryotic kingdom, which includes heterokont algae and water molds. LÄS MER

  7. 5. Functional characterization of cellulose and chitin synthase genes in Oomycetes

    Författare :Johanna Fugelstad; Vincent Bulone; Carol Munro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellulose biosynthesis; chitin biosynthesis; cellulose synthase gene; chitin synthase gene; Oomycetes; Phytophthora infestans; Saprolegnia monoica; pleckstrin homology domain; Microbiology; Mikrobiologi;

    Sammanfattning : Some species of Oomycetes are well studied pathogens that cause considerable economical losses in the agriculture and aquaculture industries. Currently, there are no chemicals available that are environmentally friendly and at the same time efficient Oomycete inhibitors. LÄS MER
