Newly discovered algal enzyme could help improve efficiency of photosynthesis and boost crop productivity


For plants and algae that carry on photosynthesis, light can be too much of a good thing. On a bright, sunny day, a plant might only be able to utilize 20 percent or less of absorbed sunlight. The plant dissipates the excess light energy to prevent damage and oxidative stress, and a process called the xanthophyll cycle helps to flip the switch between energy dissipation and energy utilization.
