Background

Harvesting and transduction of light into chemical energy, with concomitant splitting of water molecules, are unique for oxygenic photosynthetic membranes composed of structurally and functionally highly differentiated membrane protein complexes. Our research from one hand aims at understanding the regulatory pathways that govern the biogenesis, performance and acclimation of the photosynthetic protein complexes in the thylakoid membrane. From the other hand, we also resolve signaling pathways initiated by chloroplast photosynthetic reactions and relayed into the nucleus to regulate the growth and development of plants. Knowledge gained on photosynthetic reactions is used for applied research aiming at solar fuel production.

 

Research

Most attention so far has been put on Photosystem (PS) II composed of nearly 30 different protein subunits and more recently also on the NDH complex, both complexes being composed of subunits encoded by the chloroplast and the nuclear genomes. Identification and role of translocon components, molecular chaperones and other folding factors in the thylakoid membrane, in stroma and in the thylakoid lumen during translation, insertion and assembly of chloroplast-encoded thylakoid membrane proteins are being addressed. As chloroplasts have developed from prokaryotic progenitors, we investigate in parallel the regulation and assembly of both the cyanobacterial and chloroplast thylakoid membrane complexes. PS II repair cycle and the turnover of the D1 protein, regulated by PSII core protein phoshorylation in chloroplasts, are under thorough investigation as well as the distribution of excitation energy between PSII and PSI as regulated by chloroplast thylakoid kinases. Cyanobacterial NDH-1 complexes were shown to be particularly versatile. We have identified two distinct NDH-1 complexes, NDH-1L and NDH-1MS and showed the functional roles for these complexes in respiration, cyclic electron flow around PSI and carbon acquisition. Also a huge dynamics in the expression of these complexes was demonstrated according to different environmental cues. The structure of the NDH-1 complexes has recently been addressed in collaboration with Prof. E. Boekema group. Most recent experiments also focus on flavodiiron proteins (Flv 1-4) in cyanobacterial membranes and their role in regulation of electron transfer and/or carbon acquisition.

In addition to the harvesting of sunlight, the chloroplasts also function as "receptors" of environmental signals. We aim at system biology view on the chloroplast-derived regulation of nuclear gene expression by environmental cues, including redox and metabolite signaling. Redox signaling from chloroplasts to the nucleus is likely to be an important component in various stress responses and acclimation of plants but also metabolites derived from CO₂ fixation are important regulators of nuclear gene expression. Information on global redox regulation of nuclear genes by chloroplast signals is obtained by transcript profiling and proteomics approaches.

Solar fuels are an applied focus of our research. Direction of the light energy absorbed by photosynthetic pigments to the production of biofuels at the earliest possible phase would increase the photon conversion efficiency into biofuels as compared to any system where the captured energy is first converted to biomass. Photosynthetic microorganisms have a flexibility to "directly" produce biofuels. We focus on cyanobacteria and enhance their capability in biofuel production making use of both the natural diversity of cyanobacteria and genetic engineering. [ more... ]
