abstract = "Non-thermal temperature plasmas (NTPs) have rich chemistry of Reactive Oxygen and Nitrogen Species (RONS) that are formed in gas phase and, in case of water treatment, in gas/liquid interface in liquid [1]. NTPs can be applied in direct treatments of plant samples or indirectly when treated water, called Plasma Activated Water (PAW), is used in treatments. In both cases RONS (short or long-living) are responsible for triggering various mechanisms and effects in plant cells. RONS have a dual role and a dose-dependent effect, they can regulate the normal physiological activities of plants as signaling molecules at the range of physiological concentration, and can trigger damage to lipids, proteins and DNA at too high or too low concentration. Plants integrate RONS with genetic, epigenetic and external signals to regulate developmental processes. RONS signaling is highly integrated with hormonal signaling networks, thereby allowing plants to adjust to environmental cues.
All organisms have adaptive responses to oxidative stress, with antioxidant enzymes (i.e. catalase, peroxidase, superoxide dismutase) being induced by changes in the levels of H2O2 or O2 •-, leading to the activation or silencing of genes encoding defensive enzymes and transcription factors [2]. Although various observations have led to the suggestion that cells have the means to sense RONS and to induce specific responses, the underlying mechanisms are still not fully understood. In addition, plants also have non-enzymatic systems known to remove RONS, which are important players in plant processes that use RONS-dependent signaling mechanisms [3]. In this work, we have shown, by using molecular approaches, how PAW treatment affect expression of genes coding for specialized metabolites and hormones, thus regulating development and stress responses in the model plant system Arabidopsis thaliana.",
