Lab-evolved cyanobacteria survive minute-by-minute light swings, offering clues to hardier crops

Plant scientist Dario Leister and his team are investigating how cyanobacteria adapt to rapidly changing light intensities. This could help optimize photosynthesis in crops. Photosynthesis is one of the most complex processes in nature. However, plants use only a fraction of the available light spectrum and are highly sensitive to environmental stressors such as changing light intensities, heat and drought. As climate change intensifies these stresses, safeguarding crop productivity is becoming an increasingly urgent challenge.
