1. The Small Cab-like Proteins in the cyanobacterium Synechocystis sp. PCC 6803
Sammanfattning : The Small Cab-like Proteins (SCPs) in the cyanobacterium Synechocystis sp. PCC 6803 accumulate in cells grown under different stress conditions. Genes coding for SCPs have been found in all sequenced organisms performing oxygenic photosynthesis and even in the genomes of cyanophages. LÄS MER
2. Investigating the molecular mechanism of photoprotection, qH, in Arabidopsis thaliana
Sammanfattning : Photoprotection mechanisms in plants play a crucial role in maintaining photosystem integrity and preventing photooxidative damage. In this study, we aimed to identify new molecular players involved in the qH process, a sustained photoprotective mechanism. LÄS MER
3. Beyond carbon-limitation : A re-evaluation of the ecological role of photorespiration and direct oxygen photoreduction in seagrasses
Sammanfattning : Seagrasses living in shallow coastal waters are regularly subjected to changes in environmental conditions including the two essential factors for photosynthesis: dissolved inorganic carbon (DIC) and irradiance. This thesis focuses on the photosynthetic responses of seagrasses to carbon limitation induced by community metabolism and/or high light intensities. LÄS MER
4. Violaxanthin De-epoxidase and the Xanthophyll Cycle
Sammanfattning : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. LÄS MER
5. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae
Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER
