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

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

    Abstract : 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. READ MORE

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

    Author : Nomchit Kaewthai; Harry Brumer; Jocelyn Rose; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabiodopsis thaliana; Hordeum vulgare; plant cell wall; xyloglucan; glycoside hydrolase family 16; xyloglucan endo-transglycosylase hydrolase gene family; xyloglucan endo-hydrolase; heterologous protein expression; Pichia pastoris; T-DNA insertion; in situ XET XEH assay; high-througput screening; Plant physiology; Växtfysiologi; Biochemistry; Biokemi; Functional genomics; Funktionsgenomik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : ABSTRACT The 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. READ MORE

  5. 3. Metabolic engineering of starch synthesis in barley

    Author : Staffan Ahlandsberg; Sadequr Rahman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hordeum vulgare; plant breeding; starch; genetic engineering; transgenic plants; biokemi; Biochemistry;

    Abstract : 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. READ MORE

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

    Author : Dace Apoga; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. Adhesion of B. READ MORE

  7. 5. Barley defense genes against aphids

    Author : Aleksandra Losvik; Lisbeth Jonsson; Ulla Rasmussen; Robert Glinwood; Bogumił Leszczyński; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aphid resistance; protease inhibitor; lipoxygenase; induced plant resistance; volatiles; Hordeum vulgare; Rhopalosiphum padi; Myzus persicae; Plant Physiology; växtfysiologi;

    Abstract : 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. READ MORE
