Vishwakarma et al. treat wild-type and aox1a knock-out mutants of Arabidopsis thaliana with antimycin A and find that restriction of the cytochrome c oxidase (COX) pathway in the background of an impaired AOX pathway results in a substantial decrease in respiration, photosynthesis, chloroplastic heat dissipation, ascorbate level and antioxidant systems.
Sandalio and Romero-Puertas review the metabolism of reactive oxygen and nitrogen species (ROS and RNS) in peroxisomes and their contribution to the regulation of plant development and acclimation to stress conditions.
de Pinto et al. provide an overview of the redox pathways that contribute to how plants cope with heat stress, focussing on the roles of reactive oxygen species (ROS), redox metabolites and enzymes in the signalling pathways leading to the activation of defence responses.
