  2. 1. Constraint-based modeling of yeast metabolism and protein secretion

    Author : Feiran Li; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein secretion; metabolism; yeast evolution; genome-scale metabolic model; phenotype diversity;

    Abstract : Yeasts are extensively exploited as cell factories for producing alcoholic beverages, biofuels, bio-pharmaceutical proteins, and other value-added chemicals. To improve the performance of yeast cell factories, it is necessary to understand their metabolism. READ MORE

  4. 2. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics

    Author : Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptation; divergence; selection; experimental evolution; genomics; genome evolution; population genetics; fission yeast; phenotypic variation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. READ MORE

  5. 3. Bioreduction of Carbonyl Compounds to Chiral Alcohols by Whole Yeast Cells: Process Optimisation, Strain Design and Non-Conventional Yeast Screening

    Author : Michael Katz; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bicyclic diketone; carbonyl; yeast; candida; cerevisiae; reductase; ketone; reduction; whole cell; YMR226c; YDR368w; Microbiology; bacteriology; virology; mycology; Biokemisk teknik; Biochemical technology; mykologi; virologi; Mikrobiologi; bakteriologi;

    Abstract : Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. READ MORE

  6. 4. Hopeful monsters: The role of hybrids in adaptation : The impact of hybridisation and genetic diversity on adaptation to stressful and novel environments

    Author : Ciaran Gilchrist; Rike Stelkens; Christopher Wheat; Linda Laikre; Mathilde Cordellier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Saccharomyces cerevisiae; population genetics; hybridisation; adaptation; aneuploidy; comparative genomics; evolve-and-resequence; de novo mutations; evolutionary parallelism; populationsgenetik; Population Genetics;

    Abstract : Adaptation to novel environments can only occur if natural selection has the raw material to act upon. But small, endangered populations are often genetically depleted, and the acquisition of beneficial de novo mutations often takes too long when population face quick and extreme environmental change.

  7. 5. The evolution of the nuclear envelope

    Author : Nadja Neumann; Anthony Poole; Gáspár Jékely; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear pore complex; bouquet; meiosis; nucleus; eukaryote evolution; nucleoporin; tree of life; stem group; recombination; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : The nucleus is one of the defining features of eukaryotes and the question of its origin is intimately linked to the evolution of the eukaryotic cell. It is delimited by a double lipid bilayer called the nuclear envelope, which separates the nuclear interior from the cytoplasm. READ MORE
