How seagrass survives in low light could help future crops

Scientists have discovered how the Mediterranean seagrass Posidonia oceanicahas adapted its photosynthetic system to survive in the dim, blue-green light of the seabed. The plant captures more light while moving energy more efficiently by altering its photosynthetic machinery. Researchers say the findings could help develop crop plants that make better use of limited sunlight under dense canopies.
