Description

With contributions that review research on this topic throughout the world, Oxidative Damage to Plants covers key areas of discovery, from the generation of reactive oxygen species (ROSs), their mechanisms, quenching of these ROSs through enzymatic and non-enzymatic antioxidants, and detailed aspects of such antioxidants as SOD and CAT.

Environmental stress is responsible for the generation of oxidative stress, which causes oxidative damage to biomolecules and hence reduces crop yield. To cope up with these problems, scientists have to fully understand the generation of reactive oxygen species, its impact on plants and how plants will be able to withstand these stresses.

Key Features

  • Provides invaluable information about the role of antioxidants in alleviating oxidative stress
  • Examines both the negative effects (senescence, impaired photosynthesis and necrosis) and positive effects (crucial role that superoxide plays against invading microbes) of ROS on plants
  • Features contributors from a variety of regions globally

Readership

Researchers, academics and students in plant ecophysiology, plant biochemistry, plant molecular biology, plant pathology, environmental sciences, and agronomy.
