Abstract: Abstract Efficient quenching of (bacterio)chlorophyll triplet states by carotenoids prevents formation of reactive singlet oxygen in photosynthetic light-harvesting complexes. This protective process requires a close interaction between both types of pigments, which is usually ensured… read more here.

Abstract: Photosynthesis—both oxygenic and more ancient anoxygenic forms—has fueled the bulk of primary productivity on Earth since it first evolved more than 3.4 billion years ago. However, the early evolutionary history of photosynthesis has been challenging… read more here.
