Die Rolle von Photorespiration unter dynamischen Lichtbedingungen

Abstract

AbstractPlants use photosynthesis to convert light into metabolic energy. This energy is used to produce carbohydrates and to fuel other metabolic pathways. In nature, the availability of light and thereby metabolic energy can fluctuate strongly, leading to inefficient metabolism and photodamage. The photorespiratory pathway (PR) was hypothesized to mitigate harmful effects. Our results do not support this but identify an alternative branch of PR in silico that may benefit the plant under fluctuating light.
