Photosynthesis Differs in Rice Varieties — Natural Diversity Could Boost Yields

Rice is a direct source of calories for more people than any other and serves as the main staple for some 560 million chronically hungry people in Asia. With over 120,000 varieties of cultivated rice (Oryza sativa) across the globe, there is a wealth of natural diversity to be mined by plant scientists to increase yields. A team from the University of Illinois and the International Rice Research Institute (IRRI) examined how 14 diverse varieties photosynthesize—the process by which all crops convert sunlight energy into sugars that ultimately become our food.

Solar Cell Made of a Single Molecule: Electrical Current Generated from Individual Protein Complex

  A method to measure the photocurrents of a ‘single functionalized photosynthetic protein system’ has now been developed by researchers. The researchers are confident that they can show that such a system could be integrated and “selectively addressed” inside of an artificial photovoltaic device’s architecture while still being able to … [continued]
