  1. 1. Skillnader mellan granindivider gällande initieringsfrekvens för somatisk embryogenes

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Josefine Björs; Jonathan Sjögren; [2023]
    Nyckelord :skogsträdsförädling; Picea abies; fröklonförökning;

    Sammanfattning : Gran (Picea abies) har länge varit ett viktigt trädslag för den svenska skogsnäringen. Skogsbruket står inför en oviss framtid och med ett alltmer ostadigt klimat behövs ett genetiskt material som kan klara dessa nya prövningar. LÄS MER

  3. 2. CRISPR-Drawr, a tool to design mutagenic primer

    Magister-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Larsson Torbjörn; [2023]
    Nyckelord :Integrated CRISPR design; new score method; short open reading frames; functional screening; bioinformatics;

    Sammanfattning : Short open reading frames (sORFs) are codon sequences with a start and stop codon within atmost 100 codons. Cells produce many transcripts from them and some sORFs have been found to have function. sORFs have been associated with embryogenesis, myogenesis, immunity and various diseases including cancers.

  4. 3. Assessing the relationship between hypoxia and life on Earth, and implications for the search for habitable exoplanets

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Thomas Evan Smith; [2022]
    Nyckelord :hypoxia; hypoxia-inducible factors; atmospheric oxygen; multicellularity; embryogenesis; exoplanets; white dwarfs; oxygen fugacity; Earth and Environmental Sciences;

    Sammanfattning : Atmospheric oxygen at the level of present-day Earth (21%) is generally regarded as permissive for the development and survival of complex multicellular life, such as animals. The hypothesis that oxic conditions are conducive for multicellular life has subsequently been applied to the search for life elsewhere in the universe, with planets exhibiting atmospheric oxygen of a similar level to Earth being considered as candidates for habitability.

  5. 4. The use of tissue culture methods for producing resistant material of Aesculus hippocastanum : a literature study

    Kandidat-uppsats, SLU/Dept. Of Plant Breeding

    Författare :Johan Pettersson; [2020]
    Nyckelord :Aesculus hippocastanum; resistance; tissue culture; micropropagation; somatic embryogenesis; mikroförökning; somatisk embryogenes;

    Sammanfattning : The horse chestnut Aesculus hippocastanum is a European species of broadleaf trees classified as vulnerable. The species is subjected to many pathogens and pests threatening its survival. Resistance to some pathogens of horse chestnut has been investigated and tissue culture methods such as somatic embryogenesis have been successful. LÄS MER

  7. 5. Effekter av inkuberingstemperatur hos juvenil atlantlax (Salmo salar L.)

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Oscar Adolfsson; [2018]
    Nyckelord :Climate change; salmon; body shape; parr; Lax; Klimatförändringar; kroppsform; parr;

    Sammanfattning : Rising temperatures, because of climate change, will have major consequences for the world's fish populations, including the Atlantic salmon Salmo salar L. The greatest temperature changes are expected to occur during winter, which will affect S. salar since the eggs are developing during this time of year. LÄS MER
