Experts Unlock Key to Photosynthesis, A Find That Could Help Us Meet Food Security Demands
The study, led by the University of Sheffield and published today (Wednesday 13 November 2019) in the journal Nature, reveals the structure of cytochrome b6f – the protein complex that significantly influences plant growth via photosynthesis.
Photosynthesis is the foundation of life on Earth providing the food, oxygen and energy that sustains the biosphere and human civilisation.
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.
Lorna Malone, the first author of the study and a PhD student in the University of Sheffield’s Department of Molecular Biology and Biotechnology, said: “Our study provides important new insights into how cytochrome b6f utilises the electrical current passing through it to power up a ‘proton battery’. This stored energy can then be then used to make ATP, the energy currency of living cells. Ultimately this reaction provides the energy that plants need to turn carbon dioxide into the carbohydrates and biomass that sustain the global food chain.”

Dr Matt Johnson, reader in Biochemistry at the University of Sheffield and one of the supervisors of the study added: “Cytochrome b6f is the beating heart of photosynthesis which plays a crucial role in regulating photosynthetic efficiency.
“Previous studies have shown that by manipulating the levels of this complex we can grow bigger and better plants. With the new insights we have obtained from our structure we can hope to rationally redesign photosynthesis in crop plants to achieve the higher yields we urgently need to sustain a projected global population of 9-10 billion by 2050.”
The research was conducted in collaboration with the Astbury Centre for Structural Molecular Biology at the University of Leeds using their cryo-electron microscope facilities.
Researchers now aim to establish how cytochrome b6f is controlled by a myriad of regulatory proteins and how these regulators affect the function of this complex.
