Summary

h level of subcellular compartmentalization is as an evolutionary hallmark of eukaryotic cells. The existence of cellular compartment requires a complex system of regulations and signaling ensuring proper functioning of all biological processes in higher organisms. In plants, similarly to other organisms, reactive oxygen species (ROS) and nitrogen (RNS) species are known to be involved in controlling mechanisms of multiple molecular processes of growth, development and response to environmental stimuli. Production of individual ROS and RNS species is highly localized and controlled by compartment-specific enzymatic pathways regulated on transcriptional and post-translational control. Moreover, actual ROS and RNS levels in each compartment are influenced by their mutual chemical reactions and interactions with specific cellular antioxidants and scavengers. However, under specific condition, high induction of ROS- and RNS-producing cellular systems or their defective scavenging can result in oxidative or nitrosative stress conditions leading to irreversible damage to cellular components including nucleic acid, proteins and lipids. In this review current knowledge on molecular mechanisms involved in ROS and RNS production and homeostasis in different plant cell compartments will be summarized and future directions of ROS and RNS studies in higher plants presented.
