    Abstract : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. READ MORE

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

    University dissertation from Uppsala, Sweden : Acta Universitatis Upsaliensis

    Author : Kuk-ki Hong; [2012]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations a continuum of integration and diversification through geological time

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Andrea Caputo; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; diatoms; cyanobacteria; diazotrophs; symbiosis; evolution; phylogenetics; confocal microscopy; qPCR; CARD-FISH; tropics; sub-tropics; marin ekologi; Marine Ecology;

    Abstract : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

  4. 4. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

    University dissertation from Lund University, Faculty of Science, Department of Biology

    Author : Anna Nordén; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2017-11]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Hermaphrodite; Inter-sexual genetic correlation; Quantitative genetics; Macrostomum lignano; Experimental evolution; Sexual conflict;

    Abstract : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. READ MORE
