Whether flavonoids play significant antioxidant roles in plants challenged by photooxidative
stress of different origin has been largely debated over the last few decades. A critical review …

Reactive oxygen species (ROS) are produced as a normal product of plant cellular
metabolism. Various environmental stresses lead to excessive production of ROS causing …

Plants adapt to environmental stresses through specific genetic responses. The molecular
mechanisms associated with signal transduction, leading to changes in gene expression …

This chapter proposes that whether reactive oxygen species (ROS) act as signal transducing
or damaging molecules is mainly dependent on their quality and second, on their quantity …

Although UV-B is a minor component of sunlight, it has a disproportionately damaging effect
on higher plants. Ultraviolet-sensitive targets include DNA, proteins and membranes, and …

Since the publication of the third edition of the Handbook of Plant and Crop Stress,
continuous discoveries in the fields of plant and crop environmental stresses and their …

Recent measurements of ozone levels have led to concern that the stratospheric ozone
layer is being depleted as a result of contamination with man-made chlorofluorocarbons …

During the past few years, considerable progress has been made in understanding how
plants protect themselves against oxidative stress. Genes encoding plant antioxidant …

There is an abundant literature about the biological and physiological effects of UV-B light
and the signaling and metabolic pathways it triggers and influences. Much less is known …

We have assessed ultraviolet-B (UV-B)-induced injury in wild-type Arabidopsis thaliana and
two mutants with altered aromatic secondary product biosynthesis. Arabidopsis mutants …
