Experts Unlock Key to PhotosynthesisNovember 20, 2019
Scientists led by The University of Sheffield have solved the structure of one of the key components of photosynthesis, a discovery that could lead to photosynthesis being ‘redesigned' to achieve higher yields and meet urgent food security needs. The study reveals the structure of cytochrome b6f - the protein complex that significantly influences plant growth via photosynthesis.
Using a high-resolution structural model, the team found that the protein complex provides the electrical connection between the two light-powered chlorophyll-proteins (Photosystems I and II) found in the plant cell chloroplast that convert sunlight into chemical energy. The high-resolution structural model, determined using single-particle cryo-electron microscopy, reveals new details of the additional role of cytochrome b6f as a sensor to tune photosynthetic efficiency in response to ever-changing environmental conditions. This mechanism is protecting the plant from damage during exposure to stressful conditions such as drought or excess light.
