  1. 21. Temperature and the synchrony of plant-insect interactions

    Författare :Tenna Toftegaard; Johan Ehrlén; Karl Gotthard; Christer Wiklund; Annette Menzel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brassicaceae; Anthocharis cardamines; climate change; development; oviposition; phenology; species interactions; herbivory; synchrony; timing; phenotypic plasticity; local adaptation; Plant Ecology; växtekologi;

    Sammanfattning : Increasing temperatures resulting from climate change have within recent years been shown to advance phenological events in a large number of species worldwide. Species can differ in their response to increasing temperatures, and understanding the mechanisms that determine the response is therefore of great importance in order to understand and predict how a warming climate can influence both individual species, but also their interactions with each other and the environment.

  3. 22. Host organelles and transporters in underground plant-pathogen interactions

    Författare :Fredrik Dölfors; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  5. 24. Microbotryum violaceum on Silene dioica : understanding traits that influence plant-pathogen interactions

    Författare :Åsa Granberg; Barbara E. Giles; Ulla Carlsson-Granér; Arjen Biere; Umeå universitet; []
    Nyckelord :plant-pathogen interaction; biochemical resistance; breeding system; automixis; race specific resistance; extinction-colonisation dynamics; Silene dioica; Microbotryum violaceum;

    Sammanfattning : The dynamics of a plant-pathogen interaction vary both within and among species. Both spatial structuring and specific genetic and life-history characteristics will affect the interaction and the outcome of a potential co-evolution between the two organisms. LÄS MER

  7. 25. Studies towards late blight control in potato

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

    Sammanfattning : 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. LÄS MER
