  2. 1. Past demography and local adaptation in forest trees : Insights from natural populations and breeding programs of Norway spruce

    Author : Lili Li; Martin Lascoux; Brunno Fady; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clines; demographic history; local adaptation; Picea abies; Picea obovata; population genetic structure; Swedish breeding program; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Spatial changes in natural selection patterns can give rise to local adaptation and genetic differentiation between populations. Local adaptation for phenological traits is pronounced in many forest tree species. READ MORE

  4. 2. A forest dark : an evolutionary history of Norway spruce

    Author : Alexis R. Sullivan; Xiao-Ru Wang; Nathaniel Street; María Rosario García-Gil; Bengt Oxelman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phylogenetics; genome assembly; recombination; Picea; hybridization; mitogenome; Norway spruce; phylogeography; phylogenetic networks; plastome;

    Abstract : 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. READ MORE

  5. 3. Proteomics and metabolomics in biological and medical applications

    Author : Liudmila Shiryaeva; Wolfgang P. Schröder; Pernilla Wikström; Peter Roepstroff; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2D-DIGE; biomarkers; cold-acclimation; conifer; freezing tolerance; GC-MS; metabolomics; multiple hypothesis test; multivariate analysis; OPLS-DA; Picea obovata; plasma; prostate cancer; proteomics; ProteoMiner; Siberian spruce;

    Abstract : Biological processes in living organisms consist of a vast number of different molecular networks and interactions, which are complex and often hidden from our understanding. This work is focused on recovery of such details for two quite distant examples: acclimation to extreme freezing tolerance in Siberian spruce (Picea obovata) and detection of proteins associated with prostate cancer.

  6. 4. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus

    Author : Jun Chen; Martin Lascoux; Ulf Lagercrantz; Matt Olson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Speciation; Demographics; clinal variation; convergent evolution; transcriptome; small regulatory RNA; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : 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.
