ABSTRACT
Abstract. Reactive oxygen species (ROS) are often considered as a common denominator for most known abiotic and biotic stresses affecting plant performance under adverse environmental conditions. This list includes salinity-one of the major abiotic stresses that result in the multibilliondollar penalties to agricultural crop production around the globe. While the causal relationship between stress-induced ROS production and plant adaptive responses to salinity is beyond any
doubt, specific details of ROS production and signaling are still far from being fully understood. This chapter summarizes recent advances in the field and describes mechanisms and signal transduction pathways linking ROS production and signaling with plant adaptation to salinity stress.
