  1. 6. Seasonal flight patterns of the Spruce bark beetle (Ips typographus) in Sweden : phenology, voltinism and development

    Författare :Petter Öhrn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The major bark beetle threat to Norway spruce (Picea abies (L.) Karst.) in Eurasia is the spruce bark beetle Ips typographus. Beetles cause damage after population build-up in defenseless trees. LÄS MER

  3. 7. Potential impact of climate change on European agriculture: a case study of potato and Colorado potato beetle

    Författare :Bakhtiyor Pulatov; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colorado potato beetle; climate change; day length; degree day model; frost damage; distribution; temperature; potato; regional climate model; synchrony;

    Sammanfattning : European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. LÄS MER

  4. 8. Streptococcus pyogenes and its interactions with the human host

    Författare :Ulrika Ringdahl; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; mykologi; virologi; bakteriologi; M protein; Streptococcus pyogenes; plasminogen; fibrinogen; phagocytosis; platelet; Microbiology; bacteriology; virology; Mikrobiologi; mycology; Infektioner; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : We have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a common 13 amino acid internal repeated sequence located in the NH2-terminal surface-exposed portion of these M proteins. LÄS MER

  5. 9. The life and death of the notch intracellular domain

    Författare :Camilla Öberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The Notch signaling pathway is an evolutionarily conserved way of communicating between cells that contact each other. Notch is a single-transmembrane spanning receptor that interacts with single-transmembrane spanning ligands on adjacent cells. In vertebrates the Notch family of receptor consists of four members: Notch1 to Notch4. LÄS MER

  7. 10. Controlling Fusarium Head Blight in oat

    Författare :Alfia Khairullina; Tillämpad biokemi; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; FHB; oat; UDP-glucosyltransferase; deoxynivalenol; mycotoxins; biocontrol; Clonostachys rosea; Fusarium head blight; Fusarium graminearum; endophytes;

    Sammanfattning : Oats (Avena sativa) is a versatile crop grown worldwide for animal feed and human consumption. Humanoat consumption has recently risen due to its various health benefits. However, oats are susceptible toFusarium head blight (FHB) caused by various Fusarium fungi. FHB reduces yield and leads to mycotoxinaccumulation. LÄS MER
