Reactive oxygen species (ROS)–the byproducts of aerobic metabolism–influence numerous
aspects of the plant life cycle and environmental response mechanisms. In plants, ROS act …

Photosynthesis is a high-rate redox metabolic process that is subjected to rapid changes in
input parameters, particularly light. Rapid transients of photon capture, electron fluxes, and …

The chloroplast can act as an environmental sensor, communicating with the cell during
biogenesis and operation to change the expression of thousands of proteins. This process …

The redox state of the chloroplast and mitochondria, the two main powerhouses of
photosynthesizing eukaryotes, is maintained by a delicate balance between energy …

Ultraviolet-B (UV-B) radiation has long been perceived as a stressor. However, a conceptual
U-turn has taken place, and UV-B damage is now considered rare. We question whether UV …

Plants and algae require light for photosynthesis, but absorption of too much light can lead
to photo‐oxidative damage to the photosynthetic apparatus and sustained decreases in the …

Generation of reactive oxygen species (ROS) is one of the earliest responses of plant cells
to various biotic and abiotic stresses. ROS are capable of inducing cellular damage by …

Reactive oxygen species (ROS) have multifaceted roles in the orchestration of plant gene
expression and gene-product regulation. Cellular redox homeostasis is considered to be an …

Plants and algae often absorb too much light—more than they can actually use in
photosynthesis. To prevent photo-oxidative damage and to acclimate to changes in their …

The old observation that plants preferentially synthesize flavonoids with respect to the wide
range of phenylpropanoid structures when exposed to high doses of UV-B radiation has …
