11th International Conference on "Photosynthesis and Hydrogen Energy Research for Sustainability".

All aerobic life on Earth depends on oxygenic photosynthesis, occurring in both prokaryotic and eukaryotic organisms. This process can be divided into light reactions and carbon fixation. This special issue is a result of the International Conference on "Photosynthesis and Hydrogen Energy Research for Sustainability 2023," held in honor of Robert Blankenship, Győző Garab, Michael Grätzel, Norman Hüner, and Gunnar Öquist. After extensive discussions on various aspects of photosynthesis and hydrogen energy, eight high-quality papers were selected. These papers cover studies on abiotic stress, an overview of photosynthesis, thylakoid membrane lipid organization, energy transfer, and the genomics of both prokaryotic and eukaryotic photosynthesis, as well as biohydrogen production from cyanobacteria. The authors used new methods and techniques, likely bringing fresh ideas for improving biomass and crop yield.
