Photosystems I and II convert solar energy into the chemical energy that powers life. Both photosystems use chlorophyll-a photochemistry, absorbing almost the same color of light and thus accessing comparable amounts of energy. This energy is considered the “red-limit” for oxygenic photosynthesis. Here we report that a trait that is common in cyanobacteria extends the photochemical red-limit, with both photosystems using ~110 meV less energy. This ~45 nm upshift of the photochemically active… CONTINUE READING
