Biochemists have been fairly confident for nearly 3 decades that they understand photosynthesis, perhaps the most important reaction in biology. But work reported on page 364 is now challenging one of the longest standing tenets of that understanding. A team at Oak Ridge National Laboratory has disabled one of the two key photosystems in photosynthesis in a single-celled alga and found that it still thrives in normal conditions. The results may force researchers to reconsider the ubiquity of the accepted two-stage scheme and may also throw light on the evolution of photosynthesis.
