1. 1. Winter wheat exudates : Improving wheats resilience to drought

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Freja Haverland; [2024]
   Keywords : drought; PGPR; exudates; agriculture; food security;

   Abstract : Wheat (Triticum aestivum) is a crop that dominates the diets of about 35% of the world's human population. But wheat yields can be severely affected by drought. Therefore, in this experiment, root exudation of winter wheat was compared to find out how exudation changes during drought stress. READ MORE

3. 2. An agroecological perspective for improving drought tolerance of wheat cultivars for Sweden

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Marwan Mohammed Ismael Alamrani; [2020]
   Keywords : wheat production; drought stress; phenotyping and new technologies;

   Abstract : Drought stress is one of the major abiotic stresses that cause losses in cereal production around the world. Drought stress causes several morphological, physiological, biochemical and molecular transformations in plants. READ MORE

4. 3. 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

   University essay from SLU/Dept. of Forest Genetics and Plant Physiology

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

   Abstract : 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. READ MORE

5. 4. 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

   University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

   Author : Anna Schyman; [2018]
   Keywords : photosynthesis; CO2; nitrogen; Picea abies; Rubisco;

   Abstract : 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. READ MORE

6. 5. A search for novel functions in the auxin metabolic pathway

   University essay from SLU/Dept. of Forest Genetics and Plant Physiology

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

   Abstract : 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. READ MORE
