Alternative electron transport mediated by flavodiiron proteins is operational in organisms from cyanobacteria up to gymnosperms

What is it about?

Photo-reduction of molecular oxygen to water mediated by flavodiiron proteins (FDPs) represents a safety valve for photosynthetic electron transport chain in fluctuating light. Here we present evidence that FDPs are functional in all groups of green plants up to gymnosperms, suggesting a major change in the strategy of photosynthetic regulation during the evolution of angiosperms.
