  1. 1. Candidate genes for resistance and susceptibility to the bird cherry-oat aphid (Rhopalosiphum padi L.) in barley (Hordeum vulgare L.)

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Författare :Sara Mehrabi; Lisbeth Jonsson; Inger Åhman; Lisa Beste; Benedicte Riber Albrectsen; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; aphid resistance; aphid susceptibility; Rhopalosiphum padi; Myzus persicae; Hordeum vulgare; växtfysiologi; Plant Physiology;

    Sammanfattning : Bird cherry-oat aphid (Rhopalosiphum padi L.) is an important pest on spring-sown cereals. The aphid reduces yield and can act as a vector of barley yellow dwarf virus. R. LÄS MER

  2. 2. In vitro and in vivo approaches in the characterization of XTH gene products

    Detta är en avhandling från Stockholm : KTH

    Sammanfattning : ABSTRACTThe xyloglucan endo-transglycosylase/hydrolase (XTH) genes are found in all vascular and some nonvascular plants. The XTH genes encode proteins which comprise a subfamily of glycoside hydrolase (GH) family 16 in the Carbohydrate-Active enZYmes (CAZY) classification. LÄS MER

  3. 3. Metabolic engineering of starch synthesis in barley

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Staffan Ahlandsberg; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hordeum vulgare; plant breeding; starch; genetic engineering; transgenic plants; biokemi; Biochemistry;

    Sammanfattning : Starch is an important industrial raw material both for food and non-food purposes. In plants, starch is deposited in the leaf and in the storage tissues such as seed endosperm, roots or tubers. LÄS MER

  4. 4. Infection biology of the plant pathogenic fungus Bipolaris sorokiniana

    Detta är en avhandling från Department of Ecology, Lund University

    Författare :Dace Apoga; Lund University.; Lunds universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microscopy; Hordeum vulgare; barley; virulence; prehelminthosporol; phytotoxins; proteins; adhesion; fimbriae; extracellular matrix; Helminthosporium sativum; Cochliobolus sativus; Plant pathogenic fungi; Bipolaris sorokiniana; two-dimensional gel electrophoresis; mass spectrometry; gas chromatography; Ecology; Ekologi;

    Sammanfattning : Bipolaris sorokiniana is a fungal pathogen causing severe disease mainly in wheat and barley worldwide. In this thesis two aspects of the infection process were investigated: the adhesion mechanism of the fungus and the role of the non-host specific phytotoxin prehelminthosporol (PHL) in the disease.

  5. 5. Barley defense genes against aphids

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Författare :Aleksandra Losvik; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aphid resistance; protease inhibitor; lipoxygenase; induced plant resistance; volatiles; Hordeum vulgare; Rhopalosiphum padi; Myzus persicae; växtfysiologi; Plant Physiology;

    Sammanfattning : Aphids are insect pests with major importance worldwide. By feeding from plant phloem, they directly withdraw nutrients. The feeding injury is often visible in the form of leaf rolling, chlorosis, necrosis or plant deformation. Their pest status is attributed also to vectoring of plant viruses. LÄS MER
