1. Plastidial phosphate transport in plants
Sammanfattning : Phosphorus is an essential element for all living organisms and is central to the genetics and energetics of life. Inorganic phosphate (Pi) is recurrently involved in protein regulation and signal transduction but also in energy transfer as a component of the ATP-molecule. LÄS MER
2. FtsH metalloproteases and their pseudo-proteases in the chloroplast envelope of Arabidopsis thaliana
Sammanfattning : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. LÄS MER
3. Interplay Between Phospholipids and Digalactosyldiacylglycerol in Phosphate Limited Oats
Sammanfattning : Phosphate is an essential nutrient. In most soils it is limiting, which has resulted in that phosphate is supplied as fertilizer to increase crop yield. Through evolution, plants have adapted several mechanisms to increase phosphate uptake from the soil and to household with acquired phosphate. LÄS MER
4. The tRNALeu (UAA) Intron of Cyanobacteria : Towards Understanding a Genetic Marker
Sammanfattning : The tRNALeu (UAA) intron has been recorded in the plastid genome of many algae and land plants and was the first intron to be discovered in cyanobacteria. In all known cases it interrupts the tRNALeu anticodon loop at a conserved position (U-intron-AA). LÄS MER
5. Phylogeny of Selaginellaceae
Sammanfattning : The phylogeny of Selaginellaceae, a small, but historically important family of heterosporous lycopods, has been the focus of this thesis. The approximately 700 extant species are herbaceous and distributed all over the world, with most species in the tropics and subtropics. LÄS MER
