Research

Cornelia Spetea performs research on regulation of photosynthesis in plants with focus on biogenesis and dynamics of photosystem II complex. This photosystem uses water and sunlight energy to produce oxygen via a unique and extremely difficult chemical reaction, which in nature can only be performed by photosystem II. The complex contains a special protein, D1, with a very high turnover (30-60 min), specially when plants are exposed to sunlight of high intensity. D1 is degraded proteolytically and replaced with a new copy. As a postdoctor in the group of Prof. Bertil Andersson at Stockholm University, Cornelia Spetea has discovered that D1 protein degradation requires guanosine triphosphate (GTP), a signal molecule in many cell types, but which was not previously known to affect photosynthesis.
Her own research group at LiU has identified novel nucleotide-dpendent processes related to photosynthesis. The group has also identified a thylakoid ATP/ADP carrier and a phosphate transporter.
The research group has moved to GU in February 2011. The ongoing projects at GU are to study ATP transport and GTP signaling during high light stress in plants, when photosystem II must be repaired, and also to identify various types of thylakoid transporters in Arabidopsis thaliana. A recently initaited project is to study how photosynthesis is affected by mycorrhiza symbiosis in Medicago truncatula. For more info, see Ongoing Projects.

Teaching

Cornelia Spetea has participated and been responsible for courses in basic education within medical bioogy and biology between 2000-2010 at LiU. Since 2011, she gives lectures in the course Plant Molecular biology and technology at GU.
