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...

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...
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...
Mechanisms for ethylene-induced aerenchyma formation
Results suggest that ethylene is perceived in all maize root tissues and cortical-cell-specific PCD is controlled downstream of ethylene perception.
Auxin and H2O2 interaction in control of root growth
One of the best-known effects of the plant hormone auxin on plant development is the inhibition of root elongation, yet the underlying mechanism remains poorly understood. Using tomato (Solanum lycopersicum) as a model...
Dehydration rate and ROS production in an aquatic moss
Desiccation induces an increase of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes as cellular water content decreases. Cruz de Carvalho et al. examine how dehydration rate influences ROS...
Aerenchyma formation in rice under flooding
Aerenchyma formation in rice under flooding One of the adaptive traits of rice that allow it to withstand submergence is the presence of aerenchyma, which allow transport of oxygen to submerged organs. Parlanti et al. ...
