  1. 1. Evolutionary conservation analysis of sequence variants underlying ecological adaptation in Atlantic herring

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Leyi Su; [2023]
    Keywords : Ecological adaptation; Evolutionary conservation; Atlantic herring;

    Abstract : The Atlantic herring (Clupea harengus) is a model organism for exploring the genetic basis of ecological adaptation on account of its large effective population size which greatly restrains the disturbance of genetic drift. In this project, I conducted an evolutionary conservation analysis of the Atlantic herring genome using conservation scores generated by phastCon, phyloP and GERP++ in order to study the sequence variants related to salinity or spawning-time adaptation in Atlantic herring.

  3. 2. A population genomic approach to investigate potential island effects in the cryptic wood white butterfly (Leptidea juvernica) : Do island populations have lower genetic diversity and less efficient selection than mainland populations?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Xuejing Hu; [2022]
    Keywords : island effect;

    Abstract : Due to limited geographic ranges, island populations, in general, are expected to have smaller population sizes and a limited influx of migrants compared to populations inhabiting continental mainlands. Therefore, island populations are expected to be influenced by genetic drift and natural selection differently from mainland populations. READ MORE

  4. 3. Genomic diversity analysis in the Swedish Landrace Goat

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Bernadett Hegedüs; [2022]
    Keywords : Swedish Landrace Goat; genetic diversity; inbreeding; runs of homozygosity; ; population structure;

    Abstract : There are four goat breeds present in Sweden. However, no genetic studies were dedicated to investigating the genetic diversity in these breeds. This thesis therefore aims to describe the population structure and the level of inbreeding in the goat breed with the largest population number, the Swedish Landrace goat. READ MORE

  5. 4. Developing a Method to Study the Impact of Microbial DNA on the Brain Related to Alzheimer’s Disease – Can Food Make a Change?

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Fuh-Tzu Yang; [2022]
    Keywords : DNA extraction; Microbiome DNA enrichment; Host DNA depletion; 16S rRNA sequencing; Alzheimer’s disease; Gut-brain axis; Microbiota; Microbial DNA; Black currant; Applied Nutrition and Food Chemistry; Medicine and Health Sciences;

    Abstract : Understanding the gut-brain-microbiota axis can help us provide a new tool to manage conditions such as Alzheimer’s. However, a major challenge is selectively amplifying the bacterial DNA which is present at a much lower level than the host DNA. READ MORE

  6. 5. Advanced Detection Methods of Genomic Barcodes for Genotyping Escherichia coli Libraries

    University essay from Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Nicole Eger; [2021]
    Keywords : Genotyping; Genomic barcodes; LAMP; PNA; RCA; FISH;

    Abstract : Pooled cell strain libraries are a powerful tool allowing to investigate the influence of genetic modifications on phenotypes in high throughput single-cell assays. To link the genotype to phenotype in each cell of the library, unique 20 base pairs (bp) long barcodes are used to allow in situ genotyping after phenotyping via fluorescence microscopy. READ MORE
