  1. 1. Evaluation of GM trees expressing a fungal enzyme : investigating the effects of the fungal enzyme on activation of jasmonate signaling using JAZ10:GUS reporter lines of Arabidopsis

    Kandidat-uppsats, SLU/Dept. of Forest Genetics and Plant Physiology

    Författare :Elin Bäckström; Therese Thalin; [2019]
    Nyckelord :cell wall formation; cell wall composition; genetic modification; genetic improvement; ; GUS;

    Sammanfattning : The fungi enzyme glucuronoyl esterase can be used to change the cell wall composition in plants for easier extraction of cellulosic biomass compounds for the production of biomaterials and biofuels. However, previous studies have shown that expression of glucuronoyl esterase in plants causes stress response, mediated by jasmonate signaling, and growth penalty. LÄS MER

  2. 2. Photosynthesis response to temperatures – A study of fertilized and unfertilized Picea abies : Fotosyntes i respons till temperatur – En studie av gödslad och ogödslad Picea abies

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Anna Schyman; [2018]
    Nyckelord :photosynthesis; CO2; nitrogen; Picea abies; Rubisco;

    Sammanfattning : The effect climate change has on forest trees is a large scaled topic. It is to believe that one of the largest threat to the environment today is global warming (IPPC, 2007). The use of fossil fuels seems to be the big threat with its greenhouse gas (GHG) emission and therefore forest is of interest. Forest contributes in several ways. LÄS MER

  3. 3. A search for novel functions in the auxin metabolic pathway

    Master-uppsats, SLU/Dept. of Forest Genetics and Plant Physiology

    Författare :Ilias El Houari; [2016]
    Nyckelord :molecular biology; plant physiology; auxin; phytohormones; genetic screening; ethyl methanesulfonate; mapping-by-sequencing; CRISPR Cas9; confocal microscopy;

    Sammanfattning : Auxins are one of the oldest phytohormones known to us, as studies on its physiological effects date back to the end of the nineteenth century. The cardinal auxin in plants is IAA, and attempts have been made to elucidate its biosynthesis and activity for over 70 years. LÄS MER

  4. 4. Development and Validation of Yeast Biosensors for Signaling Pathways

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik; Lunds universitet/Fysiska institutionen

    Författare :Felipe Gonzalo Tueros Farfan; [2016]
    Nyckelord :Xylose; yeast; signaling; Snf3 Rgt2; Snf1 Mig1; cAMP PKA; flow cytometry; high-throughput; GFP; Technology and Engineering;

    Sammanfattning : Efficient bioconversion of the pentose xylose is vital for the development of competent lignocellulose biorefineries. Although many proper attempts of metabolic engineering for recombinant xylose utilization have been made in Saccharomyces cerevisiae, growth on xylose is still far from being optimal. LÄS MER

  5. 5. Potential för odling av energiskog i Europas klimatzoner : En modelleringsstudie av hydrologiska konsekvenser vid introduktion av energiskog över stora arealer

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Jenny Svensson; [2013]
    Nyckelord :;

    Sammanfattning : De ökade globala utsläppen är ett resultat av storskalig användning av fossila bränslen som måste minska för att få till stånd en hållbar energianvändning. Åtgärder som energieffektivisering och en omställning från fossila bränslen till förnyelsebara bränslen är därför nödvändig. LÄS MER
