Reactive oxygen species: re-evaluation of generation, monitoring and role in stress-signaling in phototrophic organisms

Biochim Biophys Acta. 2014 Jun;1837(6):835-48. doi: 10.1016/j.bbabio.2014.02.005. Epub 2014 Feb 14.

Abstract

This review provides an overview about recent developments and current knowledge about monitoring, generation and the functional role of reactive oxygen species (ROS) - H2O2, HO2, HO, OH(-), (1)O2 and O2(-) - in both oxidative degradation and signal transduction in photosynthetic organisms including microscopic techniques for ROS detection and controlled generation. Reaction schemes elucidating formation, decay and signaling of ROS in cyanobacteria as well as from chloroplasts to the nuclear genome in eukaryotes during exposure of oxygen-evolving photosynthetic organisms to oxidative stress are discussed that target the rapidly growing field of regulatory effects of ROS on nuclear gene expression.

Keywords: Chloroplast; Oxidative stress; Photosynthesis; Plant cells; Reactive oxygen species; Signaling systems.
