1. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)
Sammanfattning : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. LÄS MER
2. The art of transcriptome reconstruction : with applications in Picea abies (L.) H. Karst
Sammanfattning : Transcriptome reconstruction is an important component in the bioinformatical part of transcriptome studies. When a reference genome is missing, highly fragmented or incomplete, a de novo transcriptome assembly is the transcriptome reconstruction approach of choice, since in such situations, a simple alignment (or mapping) would not necessarily give all theinformation concerning splice junctions, isoforms or even the full extent of the gene.

3. Analysis of Two Transcriptional Regulators that Affect Meristem Function : Arabidopsis thaliana TERMINAL FLOWER2 and Picea abies APETELA2
Sammanfattning : The aerial plant body is derived from undifferentiated cells in the shoot apical meristem that in Arabidopsis thaliana is active throughout the plant life cycle. Upon transition to flowering the activity of the meristem is altered and the meristem starts to produce secondary inflorescences and floral meristems instead of leaves. LÄS MER
4. A forest dark : an evolutionary history of Norway spruce
Sammanfattning : Embedded within the relationships among species is a dense forest of gene trees, each with a potentially unique and discordant history. Such widespread genealogical heterogeneity is expected, but embracing this hierarchy of discordance while reconstructing the histories of populations and species remains a major challenge. LÄS MER
5. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus
Sammanfattning : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.
