| Abstract: |
| Plants are subjected to various environmental stresses throughout their life cycle. Reactive oxygen species (ROS) play important roles in maintaining normal plant growth and improving their tolerance to stress. The ROS would be combined with calcium signals and electrical signals to form ROS wave. The ROS wave as a dynamic process that occurs within cells between different organelles, as well as between cells over long distances, which is an important signature not only for the local immune response but also for cell\|to\|cell communication. More importantly, plants integrate the ROS with external signals to promote development and environmental adaptation. It shows that ROS production and removal played a key role in plants of growth and development, organogenesis, and abiotic stress responses. This review also describes the source of ROS, function of ROS signal transduction, expression of stress response in plants and programmed cell death by ROS, and summarizes recent progress are discussed. The aim is to provide new insights about the ROS that plays a crucial role in regulating gene expression and acts as signals in cells that activate a number of different defense mechanisms to make plants actively respond to various internal or exogenous stimulus signals, finally contributing to make plants adapt to stress environment. |
