These Proceedings of the 14th International Congress on Photosynthesis are a record of the most recent advances and emerging themes in research on light energy conversion in biological systems. This volume contains 348 edited and peer-reviewed chapters from the 824 registered participants at the meeting in Glasgow, UK, in July 2007. These contributions range from summary overview presentations of plenary speakers, through invited lectures and selected topical presentations, to expanded contents of posters from research students and their supervisors. All chapters feature novel and on-going achievements in understanding photosynthesis. In the words of Professor Eva-Mari Aro, outgoing President of the International Society for Photosynthesis Research, "Having been taken for granted for centuries, research in photosynthesis has now become a matter of utmost importance for the future of planet Earth... Major initiatives are underway that will use research into natural and artificial photosynthesis for sustainable energy production....". These volumes thus provide a glimpse of the future, from the molecule to the biosphere, as seen by the some of the most active scientists in the world.
