  1. 1. Regulation of Plant Defense Genes Against Bacterial Pathogens

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Jenny Sjöström; [2021]
    Nyckelord :plant defense; PTI; FLS2; SERK1; regulation; växtförsvar; PTI; FLS2; SERK1; reglering;

    Sammanfattning : Sjukdom på grödor orsakad av bakterier kan bidra till ekonomiska förluster för bönder samt brist på mat, därför är det viktigt att utveckla nya hållbara sätt att motverka och behandla grödor mot bakterier. Idag är det mest vanliga tillvägagångssättet antibiotika men detta är inte hållbart p.g.a uppkomst av antibiotikaresistens. LÄS MER

  3. 2. Endosperm-based postzygotic hybridization barriers in Arabidopsis and Capsella

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Mohammad Foteh Ali; [2021]
    Nyckelord :Endosperm development; Parental conflict; Genetic diversity; Auxin;

    Sammanfattning : In Arabidopsis, endosperm development is very important for viable seed development. Especially, endosperm cellularization is a crucial event for embryo survival and if it fails, can lead to embryo arrest, as observed in seeds derived from interploidy and interspecies hybridization.

  4. 3. Characterizaion of the mechanism underlying auxin-induced seed arrest in Arabidopsis thaliana

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Sowmiya Devi Venkatesan; [2020]
    Nyckelord :endosperm; hybridization barriers; triploid block; auxins; RNA Polymerase IV; RNA silencing;

    Sammanfattning : In flowering plants, seeds are produced as a result of double fertilization, whereby the haploid egg cell and the diploid central cell fuse with one of the two haploid sperm cells giving rise to a diploid embryo and a triploid endosperm, respectively. The endosperm serves as the major nutrient source for the developing embryo yet the molecular mechanisms pertaining to its development are not fully understood. LÄS MER

  5. 4. How low levels of glucose and tryptophan may signal changes in development and symbiotic potential of ectomycorrhizal fungus Laccaria bicolor

    Master-uppsats, Umeå universitet/Institutionen för fysiologisk botanik

    Författare :Alexandra Goetsch; [2020]
    Nyckelord :;

    Sammanfattning : Symbiosis between tree species and ectomycorrhizal fungi is a fundamental relationship that promotes the overall health of boreal and temperate forests. Nutrient exchange between the two organisms is mutualistic in nature however establishment of this relationship is still not fully understood. LÄS MER

  7. 5. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients

    Master-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Kristina Weimers; [2020]
    Nyckelord :Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

    Sammanfattning : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. LÄS MER
