Abstract

SUMMARY Reactive oxygen species (ROS) such as singlet oxygen, superoxide (O 2 ●− ) and hydrogen peroxide (H 2 O 2 ) are the markers of living cells. Oxygenic photosynthesis produces ROS in abundance, which act as a readout of a functional electron transport system and metabolism. The concept that photosynthetic ROS production is a major driving force in chloroplast to nucleus retrograde signalling is embedded in the literature, as is the role of chloroplasts as environmental sensors. The different complexes and components of the photosynthetic electron transport chain (PETC) regulate O 2 ●− production in relation to light energy availability and the redox state of the stromal Cys‐based redox systems. All of…
