Mediterranean seagrass survives in dim seabed light by expanding its photosynthetic antenna and trapping energy faster, a discovery that may help improve future crops

• Scientists have uncovered how Posidonia oceanica adapted to the dim light of the seabed.
• In the Mediterranean Sea, vast underwater meadows of seagrass grow in places where sunlight is weak.
• Yet these plants continue to photosynthesise efficiently, produce oxygen, store carbon and suppor marine life.
