    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

  4. 2. Regulation of sterol and glycoalkaloid biosynthesis in potato (Solanum tuberosum L.) : identification of key genes and enzymatic steps

    Author : Nurun Nahar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Steroidal glycoalkaloids (SGA) are toxic secondary metabolites present in some members of the Solanaceae family, including potato and tomato. The SGA level in tubers of potato (Solanum tuberosum L.) depends on genetic factors, but can also increase in response to e.g. READ MORE

  5. 3. Modulation of the glycoalkaloid biosynthesis pathway in potato (Solanum tuberosum L.) and development of CRISPR/Cas9 methodology for tomato (Solanum lycopersicum L.)

    Author : Ying Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Steroidal glycoalkaloids (SGAs) are toxic defence substances present in Solanum species, including the tomato and potato. Concerns about SGA toxicity have long been raised regarding table potato cultivars, and more recently regarding starch potato cultivars, where SGAs negatively affect the use of proteins and fibre from starch by-products.

  6. 4. Role of semiochemical in host finding, oviposition and sexual communication in Guatemalan potato moth Tecia solanivora

    Author : Miriam Frida Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Semiochemicals are important cues in the interaction between plant and insects and between conspecific insects. Volatile compounds emitted by plants provide herbivorous insects with cues for host finding, selection and discrimination. In moths, female emitted sex pheromones enable conspecific males to find them for mating. READ MORE

  7. 5. Effect of wounding and light exposure on sterol, glycoalkaloid, and calystegine levels in potato plants (Solanum tuberosum L. group Tuberosum)

    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Steroidal glycoalkaloids (SGA) are neurotoxic substances that are present in some members of the Solanaceae family, including crop species like potato (Solanum tuberosum L.) and tomato. READ MORE
