Reactive oxygen species (ROS) are key signalling molecules that enable cells to rapidly
respond to different stimuli. In plants, ROS play a crucial role in abiotic and biotic stress …

Abstract 'Reactive oxygen species'(ROS) is a generic term that defines a wide variety of
oxidant molecules with vastly different properties and biological functions that range from …

Reactive oxygen species (ROS) are essential for life and are involved in the regulation of
almost all biological processes. ROS production is critical for plant development, response …

The discoveries leading to our present understanding of the glutathione peroxidases (GPxs)
are recalled. The cytosolic GPx, now GPx1, was first described by Mills in 1957 and claimed …

Nano-and microplastics have been widely spread in environmental matrices, especially in
marine and terrestrial systems. In this study, higher plant Vicia faba root tips were exposed to …

As fixed organisms, plants are especially affected by changes in their environment and have
consequently evolved extensive mechanisms for acclimation and adaptation. Initially …

The sulfur biochemistry of the thiol group endows cysteines with a number of highly
specialized and unique features that enable them to serve a variety of different functions in …

Significance: The selenium-containing Glutathione peroxidases (GPxs) 1–4 protect against
oxidative challenge, inhibit inflammation and oxidant-induced regulated cell death. Recent …

Rapid production of H2O2 is a hallmark of plant responses to diverse pathogens and plays a
crucial role in signalling downstream of various receptors that perceive immunogenic …

An unanswered question in human health is whether antioxidation prevents or promotes
cancer. Antioxidation has historically been viewed as chemopreventive, but emerging …
