  1. 6. The role of WRKY 15 in xylem development and salt response in Arabidopsis thaliana

    University essay from SLU/Dept. Of Plant Biology

    Author : Johanna Karlsson; [2023]
    Keywords : WRKY15; VND; xylem; salinity; water availability;

    Abstract : Xylem is a water-conducting tissue in vascular plants, that absorbs water from the roots and distributes it throughout the compartments, providing the plant with essential water and nutrients for its cellular processes. The xylem, divided into protoxylem and metaxylem, develops differently according to the various abiotic circumstances, in which transcription factors have a crucial role. READ MORE

  3. 7. Foliar fungal communities of naturally regenerated and nursery-produced Scots pine (Pinus sylvestris) seedlings

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Sara López Fernández; [2023]
    Keywords : Endophytes; high-throughput sequencing; foliar fungi; forest nursery; fungal community; fungal pathogens; metabarcoding; mycobiome; Pinus sylvestris; pine seedlings; Scots pine needles;

    Abstract : Endophytic fungal communities living in leaves of trees can have a significant impact on their hosts,showing both beneficial and detrimental effects. Some mutualistic fungal species protect the host against pathogens or herbivores, while pathogenic species can increase the vulnerability of the host against biotic and abiotic stresses. READ MORE

  4. 8. Modelling the effects of substituting pollinators in decline

    University essay from Lunds universitet/Matematik LTH

    Author : Axel Eriksson; [2023]
    Keywords : pollinators; plants; mutualism; competition; equilibrium populations; Mathematics and Statistics;

    Abstract : While pollination is essential for many plant species and ecosystem functions, pollinator populations worldwide are declining. This decline is largely due to abiotic changes in the environment: climate change and other anthropogenic impacts, such as pesticides and land use change. READ MORE

  5. 9. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Robert Pim; [2023]
    Keywords : tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Abstract : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. READ MORE

  6. 10. Nitrogen fixation in wheat (Triticum aestivum) : effect of Azotobacter salinestris CECT 9690 on N-accumulation

    University essay from SLU/Dept. of Soil and Environment

    Author : John Pålsson; [2023]
    Keywords : Biostimulants; Vixeran; N-uptake; N-concentration; yield; cereals;

    Abstract : Biostimulants are products that can improve nutrient availability, nutrient uptake, nutrient use efficiency and tolerance to abiotic stress with the aim to increase plant growth and yield. During the last decades, the interest in, and market for biostimulants has grown and is expected to have a large compound annual growth rate. READ MORE
