  2. 6. Cellulose Biosynthesis in Oomycetes

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

    Abstract : 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. READ MORE

  4. 7. Insights into population structure and epidemiology of Phytophthora infestans from Nicaragua

    Author : Jorge Ulises Blandón-Díaz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Late blight caused by Phytophthora infestans (Mont) de Bary is a constraint to both potato and tomato crops in the northern highlands of Nicaragua. This thesis describes studies on population structure and epidemiology of P. infestans from Nicaragua. The genotypic and phenotypic variation in isolates of P. READ MORE

  5. 8. 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. 9. Little strokes fell great oaks : small RNA in potato and Phytophthora infestans interactions

    Author : Kristian Persson Hodén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Small RNAs (sRNAs) are non-coding RNAs of approximately 20-30 nucleotides in length. sRNAs bind to Argonaute proteins (AGOs) an integrated partner of the RISC complex. sRNAs act as templates for RISC to recognize complementary mRNA transcripts which can be cleaved by AGOs and thereby cause gene inactivity.

  7. 10. The late blight pathogen, Phytophthora infestans : interaction with the potato plant and inoculum sources

    Author : Anna-Karin Widmark; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The oomycete, Phytophthora infestans, is one of the most important plant pathogens worldwide. This thesis focuses on the late blight pathogen and its host, potato (Solanum tuberosum), and the interaction between these two organisms. Resistance to P. READ MORE
