New insight into the role of plant pigments in photosynthesis uncovered [Registered]

Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis. Carotenoids, the same pigments which give orange colour to carrots and red to tomatoes, are often found together in plants with chlorophyll pigments that harvest solar energy. Their main function is photoprotection when rays of light from the sun are the most intense. However, a new study published in Science (5 April issue) shows how they capture blue/green light…
