11. Insights into biotic stress response in Arabidopsis thaliana : the roles of epigenetics and RNA silencing
Sammanfattning : Plants live in fluctuating environments that can lead to stressful conditions that threat their survival. To deal with these disturbances, plants have developed a fascinating genome plasticity that enables them to reprogram their gene expression and adapt to the new conditions. LÄS MER
12. Finding fitness : empirical and theoretical explorations of inferring fitness effects from population-level SNP data
Sammanfattning : The distribution of fitness effects (DFE) describes the likelihood that a new mutation has a specific effect on the fitness of an individual in a given population. The shape of the DFE is a result of several factors such as population size, mating system and selective environment, and can in turn influence the evolutionary potential of a species. LÄS MER
13. Functional analyses of growth and development in the liverwort Marchantia polymorpha
Sammanfattning : Land plants developed from a freshwater charophycean algae about 500 million years ago. Today, they consist of two main clades, the vascular plants and the non-vascular bryophytes including hornworts, liverworts and mosses. LÄS MER
14. New insights into the regulation of stomatal movements by red light, carbon dioxide and circadian rhythms
Sammanfattning : Stomata are small adjustable pores formed by pairs of guard cells that enable gas exchange between leaves and the atmosphere, thus directly affecting water loss and CO₂ uptake in plants. The current work focuses on the regulation of stomatal movements by red light, carbon dioxide and the circadian system and attempts to uncover molecular mechanisms that control guard cell function.

15. Functional studies of plant hexokinases and development of genetic methods in the moss Physcomitrella patens
Sammanfattning : In the field of biology, model systems are frequently used for practical reasons. Model organisms possess several features that make them easy to work with in a laboratory setting. In addition they usually have a host of established genetic tools that have been developed by the research community. LÄS MER
