As sessile oxygenic organisms with a plastic developmental programme, plants are uniquely
positioned to exploit reactive oxygen species (ROS) as powerful signals. Plants harbor …

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

Glutathione is an essential metabolite for plant life best known for its role in the control of
reactive oxygen species (ROS). Glutathione is also involved in the detoxification of …

Cryptochromes are blue-light receptors that mediate photoresponses in plants. The
genomes of most land plants encode two clades of cryptochromes, CRY1 and CRY2, which …

Chloroplasts communicate information by signalling to nuclei during acclimation to
fluctuating light. Several potential operating signals originating from chloroplasts have been …

Plants cannot survive without glutathione (γ‐glutamylcysteinylglycine) or γ‐glutamylcysteine‐
containing homologues. The reasons why this small molecule is indispensable are not fully …

Oxidative stress and reactive oxygen species (ROS) are common to many fundamental
responses of plants. Enormous and ever‐growing interest has focused on this research …

Reactive oxygen species (ROS) have a profound influence on almost every aspect of plant
biology. Here, we emphasize the fundamental, intimate relationships between light‐driven …

Plant growth and resilience require balancing an inherently oxidative metabolism with
powerful antioxidant systems that help maintain homeostasis. When the environment …
