  1. 21. Population Genetics and Genome Organization of Norway Spruce

    Författare :Hanna Larsson; Martin Lascoux; Bruno Fady; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Picea abies; demographic history; linkage disequilibrium; HMPR; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics;

    Sammanfattning : Understanding the underlying genetic causes of adaptation to local conditions is one of the main goals of population genetics. A strong latitudinal cline in the phenotypic trait of bud set is observed in present day populations of Norway spruce (Picea abies (L.) Karst). LÄS MER

  3. 22. Advancing Metabolic Engineering through Combination of Systems Biology and Adaptive Evolution

    Författare :Kuk-ki Hong; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; galactose utilization; systems biology; Ras PKA signaling pathway; evolutionary engineering; pleiotropy of evolutionary strategies;

    Sammanfattning : Understanding evolutionary strategies of microorganisms may provide opportunities foradvanced strain development with the aim to produce valuable bio-products from renewablebiomass resources. Through evolutionary processes, microorganisms can attain new traitsassociated with genetic changes that may be useful for the construction of improved strains. LÄS MER

  4. 23. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana

    Författare :Mattias Jakobsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; Genetik; cytogenetics; Genetics; sequence polymorphism; microsatellites; population structure; polyploidy; single origin; Arabidopsis thaliana; Arabidopsis suecica; genome evolution; evolutionary history; Plant genetics; Växtgenetik;

    Sammanfattning : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. LÄS MER

  5. 24. A Genetic Survey of the Pathogenic Parasite Trypanosoma cruzi

    Författare :Anh-Nhi Tran; Lena Åslund; John Kelly; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Trypanosoma cruzi; Chagas ; gene discovery; EST; sequencing; DGC3; repeats; gene family; CL Brener; trypanothione synthetase; TcTRS locus; alleles; polymorphism; RNA-binding protein; TcPTB; stage-specific expression; Genetik; Genetics; Genetik; medicinsk genetik; Medical Genetics;

    Sammanfattning : Trypanosoma cruzi, the causative agent of Chagas´ disease, is an evolutionarily ancient species with distinct biological and immunological characteristics. A fundamental understanding of the basic biology of the parasite is necessary in order to develop reliable therapeutic and prophylactic agents against T. cruzi. We have, as a part of the T. LÄS MER

  7. 25. Divergence, admixture and continuity in the human past : Demographic inference using ancient and modern genomes

    Författare :James McKenna; Mattias Jakobsson; Per Sjödin; Ida Moltke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human evolution; population genetics; ancient genomes; population continuity; divergence; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : Demographic forces shaping the genetic variation we observe today can include population divergences, admixture events and continuity through time. The advancement of high-throughput sequencing technologies, together with developments in molecular and bio-informatics methods, mean the number of ancient genomes available for inference has risen steeply.
