1. 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
2. Light, stress and herbivory : from photoprotection to trophic interactions using Arabidopsis thaliana as a model organism
Sammanfattning : Photosynthesis is the most important process for nearly all life on earth. Photosynthetic organisms capture and transfer light energy from the sun into chemical energy which in turn provides a resource base for heterotrophic organisms. Natural light regimes are irregular and vary over magnitudes. LÄS MER
3. The xanthophyll cycle, its enzymes, pigments and regulation
Sammanfattning : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.

4. Antioxidant Activity of Bolivian Plant Secondary Metabolites
Sammanfattning : Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. LÄS MER
5. Functional studies on the Light-harvesting-Like (LiL) Proteins in Cyanobacteria and Cryptophytes
Sammanfattning : The light-harvesting like (LiL) proteins are a widely spread group of proteins within photosynthetic organisms. They are membrane proteins composed of one to four transmembrane helices and – in homology to the light-harvesting complexes of algae and higher plants – at least one of these transmembrane helices contains the chlorophyll a/b-binding (CAB) domain.
