21. Characterizaion of the mechanism underlying auxin-induced seed arrest in Arabidopsis thaliana
Master-uppsats, SLU/Dept. Of Plant BiologySammanfattning : 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
22. Analysis of chlorophyll synthesis mutants xantha-m and xantha-j of Hordeum vulgare L.
Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologiSammanfattning : The xantha phenotype of barley is observable as a yellow plant and caused by an inability to correctly synthesize chlorophyll. Chlorophyll is a tetrapyrrolic pigment containing magnesium, and is integral for photosynthesis in plants. LÄS MER
23. Identifying Genetic Causes of Hybrid Necrosis in Arrabidopsis lyrata
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Deleterious gene interactions due to accumulation of individual genetic variations between different lineages are a cause of population diversification by creating reproductive barriers that ultimately lead to differentiation of species. One type of deleterious interactions is called “hybrid necrosis”, in which epistatic interactions between some plant immunity genes (usually very variable) cause autoimmunities that produce a necrotic and dwarf phenotype.

24. Studying genetics of leaf shape variation in Arabidopsis lyrata
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. LÄS MER
