Photosynthesis Research is an international journal open to papers of merit dealing with both basic and applied aspects of photosynthesis. It covers all aspects of photosynthesis research including but not limited to light absorption and emission excitation energy transfer primary photochemistry model systems membrane components protein complexes electron transport photophosphorylation carbon assimilation regulatory phenomena molecular biology environmental and ecological aspects photorespiration and bacterial and algal photosynthesis. Papers reporting research at all levels of plant organization are invited (i.e. molecular subcellular cellular whole plant canopy ecosystem and global levels). Manuscripts submitted for publication are always reviewed by recognized authorities in the field.
