    Abstract : In all vertebrate species, reproduction is a hormonally controlled process, important for growth and maturation of gonads and germ cells. Production of functional germ cells is of outmost importance to secure the survival of a species. Fish comprises 50% of the known vertebrates and are found in aquatic habitats all over the world.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gunnar Andersson; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Zoofysiologi; NATURAL SCIENCES Biology Organism biology Animal physiology; NATURVETENSKAP Biologi Organismbiologi 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.

    Abstract : 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. READ MORE
