  1. 1. Spray Induced Gene Silencing in Phytophthora infestans : investigating exogenous dsRNA application for the control of potato late blight

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Poorva Sundararajan; [2024]
    Nyckelord :Phytophthora infestans; RNAi; potato late blight; gene silencing; SIGS;

    Sammanfattning : Phytophthora infestans is an oomycete pathogen and the causal agent of late blight disease in potato and tomato. Even today, it causes massive loss to crop and economy worldwide. Current disease control strategies include breeding for resistance and extensive fungicide spray. LÄS MER

    Sammanfattning : Att stoppa utarmning av biologisk mångfald och livsmiljöer är en stor utmaning och en ödesfråga för mänskligheten. Klimatförändringar, exploatering, kalhyggesskogsbruk, intensivt brukad jordbruksmark, invasiva arter och miljögifter medför att jorden är inne i sitt sjätte utdöende. LÄS MER

  4. 3. Exploring the diversity and distribution of Sclerotinia sclerotiorum in oilseed rape through molecular techniques

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Lamiya Tabussum; [2023]
    Nyckelord :;

    Sammanfattning : Sclerotinia sclerotiorum, a fungus with a broad host range, causes plant diseases, while its closely related counterpart, Sclerotinia subarctica, has a more limited host range and prefers colder environments. Sclerotinia stem rot is a disease caused by the fungus, leading to economic losses for farmers. LÄS MER

  5. 4. Effect of Mycorrhizal Inoculation on Growth and Nutrient Uptake by Leek (Allium porrum) fertilized with Inorganic N Combined with Saturated Polonite

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Emmanuel Owusu Boateng; [2023]
    Nyckelord :Phosphorus; Arbuscular Mycorrhiza fungi; Saturated polonite; Nitrogen; Allium porrum; Sustainability; circular economy;

    Sammanfattning : The continuous rise in global population continues to increase the demand for food. Meeting this rise in demand requires an increase in agricultural input, such as applying fertilizers, including phosphorus (P). LÄS MER

  7. 5. Foliar fungal communities of naturally regenerated and nursery-produced Scots pine (Pinus sylvestris) seedlings

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Sara López Fernández; [2023]
    Nyckelord :Endophytes; high-throughput sequencing; foliar fungi; forest nursery; fungal community; fungal pathogens; metabarcoding; mycobiome; Pinus sylvestris; pine seedlings; Scots pine needles;

    Sammanfattning : Endophytic fungal communities living in leaves of trees can have a significant impact on their hosts,showing both beneficial and detrimental effects. Some mutualistic fungal species protect the host against pathogens or herbivores, while pathogenic species can increase the vulnerability of the host against biotic and abiotic stresses. LÄS MER
