Oxidative Stress Responses in Plants Frank Van Breusegem

A central theme in the response of plants to environmental stress conditions is the accumulation of reactive oxygen species (ROS). During many stress conditions such as salt, drought, heat, and pathogen infection, changes in metabolic fluxes and alterations in enzymatic activities result in the accumulation of ROS can be a major contributor to loss of growth and productivity. High levels of ROS can lead to oxidative stress which damages for example proteins and DNA, ultimately resulting in plant cell death. On the other hand, ROS evolved into potent signaling molecules that play crucial roles in abiotic and biotic stress sensing, integration of different environmental signals, and activation of stress-response networks, thereby contributing to the establishment of improved stress resilience. This Volume provides a comprehensive insight into ROS biology in plants with a focus on plant growth and development, plant defense responses, and plant acclimation to challenging environments.
