  2. 1. Microbotryum violaceum on Silene dioica : understanding traits that influence plant-pathogen interactions

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

    Abstract : 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. READ MORE

  4. 2. Interactions between natural enemies and the dioecious herb Silene dioica

    Author : Viktoria Pettersson; Barbara E. Giles; Lars Ericson; Pia Mutikainen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Delia criniventris; Caryocolum viscariella; Microbotryum violaceum; plant-herbivore interactions; plant -pathogen interactions; sex bias; sex rato; successional gradients; fitness effects; Skeppsvik Archipelago; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Abstract : About 6% of all angiosperms are dioecious. This separation of sexual function to male and female individuals, and the fundamentally different patterns of reproductive resource allocation that follows that separation, are thought to have important ecological and evolutionary consequences for plant enemy interactions.

  5. 3. Non-target Effects of Genetically Modified Trees

    Author : Patrik Blomberg; Anders Wennström; Jan Stenlid; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetically modified; GM trees; secondary metabolism; phytochemistry; Populus; transgenic; non-target effects; natural enemies; plant-pathogen herbivore interaction; environmental effects; parasitic fungi; herbivorous insect; Terrestrial ecology; Terrestisk ekologi;

    Abstract : To date, few studies have focused on the effects of genetically modified trees (GM trees) on the environment. One concern with GM trees is that they may have unanticipated effects on non-target organisms, i.e. effects on organisms that are not direct targets of the genetically modified trait. READ MORE

  6. 4. Symbiotic and pathogenic factors in plant-microbe interaction: Structural basis of C-glycoside metabolism and lipoprotein transport in bacteria

    Author : Valentina Furlanetto; Christina Divne; Mats Sandgren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plant-Bacteria Interaction; Symbiotic Communication; C-Glycosylated Compounds; Enzymatic Deglycosylation; Pathogenic Interactions; Lipoprotein Localization; Lol System; Biotechnology; Bioteknologi;

    Abstract : The communication between plants and bacteria involves a complex chemical signaling network that mediates responses to various biotic and abiotic stresses, as well as establishing symbiotic relationships between different organisms.The first part of the thesis focuses on a mechanism for symbiotic communication between plants and bacteria and more specifically on how C-glycosylated aromatic polyketide compounds produced by plants can be used as a mechanism for plants to communicate with beneficial bacteria.

  7. 5. Defence and signalling in Potato-Phytophthora infestans interactions

    Author : Ashfaq Ali; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytophthora infestans; Plant defence; hypersensitive response; resistance; susceptibility;

    Abstract : Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. READ MORE
