  2. 1. Plant pathogen defense: Signalling, resistance and cell death

    Author : Oskar N. Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas; cell death; pathogens; plant defense; hypersensitive response; glycolipid; reactive oxygen species; blumeria graminis; erysiphe pisi;

    Abstract : Pathogenic microorganisms are present everywhere in nature and infect both animals and plants. Phytopathogenic microorganisms cause diseases on plants, and are responsible for crop loss amounting in the order billions of dollars annually. READ MORE

  4. 2. Vision Based Perception for Mechatronic Weed Control

    Author : Björn Åstrand; David Slaughter; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vision-based perception; Plant recognition; Row following; Weed Control; Mechatronics in agriculture; Mobile robots;

    Abstract : The use of computer-based signal processing and sensor technology to guide and control different types of agricultural field implements increases the performance of traditional implements and even makes it possible to create new ones. This thesis increases the knowledge on vision-based perception for mechatronic weed control. READ MORE

  5. 3. Studies towards late blight control in potato

    Author : Laith Moushib; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oomycetes; plant induced resistance; sustainable agriculture; plant defence activators; plant innate immunity; potato; late blight;

    Abstract : Abstract The oomycete Phytophthora infestans, which causes the devastating late blight disease of potato, is notorious for developing resistance to conventional control strategies (fungicide application and resistance breeding by introgression of R gene). To increase our tool box of disease management strategies available to combat P. READ MORE

  6. 4. Host organelles and transporters in underground plant-pathogen interactions

    Author : Fredrik Dölfors; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis covers studies of three different soilborne plant pathogens, the two fungi, Rhizoctonia solani and Verticillium longisporum, and the protist Plasmodiophora brassicae, as well as their host responses. Based on genome sequence analysis of the pathogens and their plant hosts, different effectors and plant defence factors were predicted. READ MORE

  7. 5. Studies of genes involved in regulating flowering time in Arabidopsis

    Author : Maria Svensson; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; flowering time; fold recognition; GA biosynthesis; promoter trapping; RNA-binding; T-DNA tagging; Biology; Biologi; Naturvetenskap; Natural sciences;

    Abstract : Transition from a vegetative growth phase to flowering in plants occurs in response to both environmental conditions and endogenous signals. Identification of genes that are involved in regulating the time of flowering is of great importance in agri- and horticulture. READ MORE
