1. 1. Pharmaceutical And Immunollogical Challenge Of Fungal Pathogens

   Författare :Marios Stylianou; Constantin F. Urban; Christophe d' Enfert; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mast cells; Candida albicans; yeast to hyphal form; antifungal drugs; repurposed drugs; HTS;

   Sammanfattning : Incidences of fungal infections are on the rise in immunosuppressed people. Predominant causative agents for these mycoses are species of the genus Candida, including Candida albicans, Candida glabrata and Candida dublieniensis. Despite a wide range of emerging pathogens, C. albicans remains the leading cause. LÄS MER

3. 2. Spatial and temporal ecology of oak-associated fungal communities

   Författare :Maria Faticov; Ayco Tack; Peter Hambäck; Paula Baptista; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic and biotic forces; climate warming; community ecology; foliar fungal community; host genotype; plant microbiome; powdery mildew; seasonal dynamics; warming-by-genotype interaction; Quercus robur; soil fungal community; spatial patterns; ekologi och evolution; Ecology and Evolution;

   Sammanfattning : Plants host a large diversity of microorganisms, which includes fungi, bacteria and archaea. Among these, fungi are highly diverse, and known to play a vital role in plant health and in regulation of the essential ecosystem functions. LÄS MER

4. 3. Interactions between plants, microbes and insects

   Författare :Laura J. A. van Dijk; Ayco J. M. Tack; Arjen Biere; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aboveground–belowground interactions; Anemone nemorosa; fungal pathogens; insect herbivores; plant–pathogen–insect interactions; pollination; soil microorganisms; spatiotemporal disease dynamics; Quercus robur; ekologi och evolution; Ecology and Evolution;

   Sammanfattning : Plants interact with an astonishing diversity of insects and microorganisms. Both above- and belowground, plants are attacked by herbivores and pathogens, and interact with mutualists such as pollinating insects and beneficial microorganisms. LÄS MER

5. 4. Population biology of the clonal plant Ranunculus lingua

   Författare :Mats E. Johansson; Christer Nilsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; clonal fragmentation; emergent macrophytes; fungal pathogens; hydrochoiy; invertebrate grazing; marginal population; Peronospora gigantea Prasocuris phellandrt regional abundance; rhizome production; size-number trade-off; vegetative reproduction; water-level fluctuation;

   Sammanfattning : The scope of this thesis was to identify, describe and quantify important life-history traits for the pseudoannual aquatic plant Ranunculus lingua in different ecological settings, by comparing populations from geographically marginal vs. central habitats. LÄS MER

7. 5. Systemic fungal diseases in natural plant populations

   Författare :Anders Wennström; Lars Ericson; Peter G. Ayres; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemic diseases; rust; smut; Puccinia minussensis; Lactuca sibirica; Puccinia pulsatillae; Pulsatilla pratensis; lateral growth; abiotic factors; disease transmission; Svampsjukdomar hos växter;

   Sammanfattning : The purpose of this thesis was to study interactions between systemic fungal diseases and perennial plants. Using the systemic rust Puccinia minussensis on the host plant Lactuca sibirica, and the rust Puccinia pulsatillae on the host plant Pulsatilla pratensis, this thesis focused on: (i) the effects of systemic diseases on their hosts (ii) host and pathogen responses to abiotic factors, (iii) the importance of life history strategies for understanding host-pathogen interactions, and (iv) the evolutionary consequences of living in close associations.
