Ozgur et al. [http://dx.doi.org/10.1093/aob/mcv072] induce the formation of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes of Arabidopsis thaliana and find that relatively low concentrations of ROS are more effective for induction of the ER stress response, and that mito

Kartzinel et al. [http://dx.doi.org/10.1093/aob/mcv117] use genetic markers to determine the extent and overlap of genetically unique kudzu vines (Pueraria montana var. lobata) in multiple patches over 2 years, and find that, contrary to expectations, patches are not dominated by one or a few genets

Polyphenol oxidases (PPOs) catalyse the oxidation of monophenols and/or o-diphenols to highly reactive o-quinones, which in turn interact with oxygen and proteins to

The phylogeography, the study of the spatial and temporal history of a species, remains largely unclear for plant species in sub-tropical China. Zhang et al. [http://dx.doi.org/10.1093/aob/mcv112] use Tapiscia sinensis, an endemic tree species, as a model to study the phylogeographical history and p

Vitamin E helps to control the cellular redox state by reacting with singlet oxygen and preventing the propagation of lipid peroxidation in thylakoid membranes. Both plant

Marquez-Garcia et al. study the effects of drought in leaves and nodules of soybean (Glycine max) and find that while the physiological impact is perceived throughout the shoot, stress-induced senescence occurs only in the oldest leaf ranks.

High light activates the xanthophyll cycle and increases the production of reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), but the interrelationships between these parameters is poorly understood. Using a natural freshwater community of algae comprising Euglena species, benthic Navi

The plant ecophysiology field is intrigued and perplexed by products of photosynthesis known as soluble or non-structural carbohydrates (NSCs), compounds that are used for growth,

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.

A science communication paper shows that framing matters when people are asked about climate change fixes. The public has a natural preference for nature. However when people don’t know what is being discussed, do they really prefer nature, or a natural appearance?

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.
