  1. 21. Hur påverkas daggmaskar av markpackning?

    University essay from SLU/Dept. of Ecology

    Author : Kifilo Oumar; [2022]
    Keywords : daggmask; markpackning; vetesort; anecisk; endogeisk; epigeisk;

    Abstract : Det här arbetet gjordes med ett färdigställt dataset över antal och biomassa av daggmaskar från ett fältförsök med markpackning. Målet med arbetet har varit att undersöka om daggmaskarna har påverkats negativt av markpackning, i kombination med andra abiotiska faktorer som förekommer under varje växtsäsong. READ MORE

  3. 22. Dietary fiber content and composition in heritage wheat

    University essay from SLU/Department of Molecular Sciences

    Author : Lisa Andersson; [2022]
    Keywords : Heritage cereals; wheat; dietary fiber; fructan; Dacke; Dala Lantvete; Källunda; Ölandsvete;

    Abstract : Wheat is the main food source in the world. A secured production has however been threatened by environmental changes in combination with the need of producing more food for a growing population. As a result, there has been an increasing interest in finding new crop varieties susceptible to abiotic stress. READ MORE

  4. 23. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joseph Asanbe; [2022]
    Keywords : late Miocene; biogenic bloom; nannofossil biostratigraphy; paleo-productivity; Reticulofenestra size variation;

    Abstract : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. READ MORE

  5. 24. Application of machine learning for the clustering of wheat transcription factor proteins into families and sub-families

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Haleemath Sameena Sameer; [2022]
    Keywords : Global food security; Machine learning; Transcription factor proteins; K Mean WRKY; Clustering; Salinity;

    Abstract : Wheat plays an important role in ensuring the global food security. Salinity of soil and water poses a major threat to its production and it affects both growth and development of wheat in a negative way. Wheat plants uses certain molecular mechanisms to adapt themselves under the salt stress. READ MORE

  6. 25. Finding the physiological function of the enzyme GPCAT. : a gene expression study using Arabidopsis plants with silenced GPCAT gene

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Ida Hallström; [2022]
    Keywords : enzyme GPCAT; gene expression; glycerophosphocholine acyltransferase; GPCAT; PC recycling pathway; physiological function; sphingolipids;

    Abstract : The aim of this project was to study the enzyme Glycerophosphocholine Acyltransferase (GPCAT) and try to find its physiological function. The biochemical reaction that the enzyme GPCAT catalyses is known, but its physiological function, e.g. why and when plants need the enzyme GPCAT, is unknown. READ MORE
