Photosynthesis under light conditions different from the Earth

Researchers at the Astrobiology Center (ABC) of National Institutes of Natural Science (NINS) in Japan and their colleagues have proposed that Earth-like red-edge reflection patterns could be observed on exoplanets around M-dwarfs. They point out that the first oxygenic phototrophs are most likely to have evolved underwater to utilize visible light, as occurred in the primordial ocean on Earth.
