Phylogeography and genetic structure of a Tertiary relict tree

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

Redox markers for drought-induced nodule senescence in soybean

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.

Diurnal changes in algal xanthophyll cycle and H2O2 concentration

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

Peroxisomes and regulation of ROS/RNS signalling (Review)

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.

Role of redox homeostasis in thermo-tolerance (Review)

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.
