UV-B exposure, ROS, and stress: inseparable companions or loosely linked associates?
TLDR
It is hypothesized that low UV-B doses cause 'eustress' (good stress) and that stimuli-specific signaling pathways pre-dispose plants to a state of low alert that includes activation of antioxidant defenses.About:

Reactive oxygen species and antioxidant machinery in abiotic stress tolerance in crop plants
TL;DR: The biochemistry of ROS and their production sites, and ROS scavenging antioxidant defense machinery are described, which protects plants against oxidative stress damages.

Reactive oxygen gene network of plants
TL;DR: In Arabidopsis, a network of at least 152 genes is involved in managing the level of ROS, and this network is highly dynamic and redundant, and encodes ROS-scavenging and ROS-producing proteins.

Responses of plants to environmental stresses
TL;DR: In this article, the authors investigated the responses of plants to environmental stresses and found that plants respond to environmental stress in response to various types of stressors, such as drought and flooding.

Malondialdehyde and thiobarbituric acid-reactivity as diagnostic indices of lipid peroxidation and peroxidative tissue injury.
TL;DR: The conclusion is reached that MDA determination and the TBA test can offer, at best, a narrow and somewhat empirical window on the complex process of lipid peroxidation.
