“…1). It can be anticipated that the progress in the development of methods for detection of specific forms of ROS (Mattila et al, 2015;Noctor et al, 2016) will facilitate the research on the contribution of respective ROS-generating systems to the guard cell signaling.…”

“…Their participation in signaling pathway can only be achieved when there is a tight balance between ROS production and their scavenging [10], [11]. The involvement of ROS in developmental processes as a signaling molecule suggests that during the course of evolution, plants might have evolved the capacity to achieve a high degree of tolerance over ROS toxicity [12], [13].…”

Reactive oxygen species (ROS), a by-product of aerobic metabolism were initially studied in context to their damaging effect but recent decades witnessed significant advancements in understanding the role of ROS as signaling molecules. Contrary to earlier views, it is becoming evident that ROS production is not necessarily a symptom of cellular dysfunction but it might represent a necessary signal in adjusting the cellular machinery according to the altered conditions. Stomatal movement is controlled by multifaceted signaling network in response to endogenous and environmental signals. Furthermore, the stomatal aperture is regulated by a coordinated action of signaling proteins, ROS-generating enzymes, and downstream executors like transporters, ion pumps, plasma membrane channels, which control the turgor pressure of the guard cell. The earliest hallmarks of stomatal closure are ROS accumulation in the apoplast and chloroplasts and thereafter, there is a successive increase in cytoplasmic Ca2+ level which rules the multiple kinases activity that in turn regulates the activity of ROS-generating enzymes and various ion channels. In addition, ROS also regulate the action of multiple proteins directly by oxidative post translational modifications to adjust guard cell signaling. Notwithstanding, an active progress has been made with ROS signaling mechanism but the regulatory action for ROS signaling processes in stomatal movement is still fragmentary. Therefore, keeping in view the above facts, in this mini review the basic concepts and role of ROS signaling in the stomatal movement have been presented comprehensively along with recent highlights.

“…In this temperature range, structural changes go from amorphous (100-300 • C) to the TT phase (300-500 • C), which corresponds to a dehydration process. Initially, a reversible loss of water molecules contained in the solvation sphere, which are part of the constitutional defects related to the NbO 7 with C-H binding energies of the order of 98, 83 and 77 kcal/mol, respectively [54][55][56]. For example, monounsaturated systems will only be reactive at high temperatures in the auto-oxidation process, whereas the polyunsaturated compounds (linoleic and linolenic esters) react with molecular oxygen at room temperature [57].…”

Abstract:The catalytic properties of niobium(V) oxide (Nb 2 O 5 -CBMN) of different grades: amorphous, optical and ultra-pure, untreated or heat-treated at 400, 500, 700 and 900 • C were studied, before and after interaction with H 2 O 2 , by in situ Raman, FTIR-ATR and diffuse reflectance UV-Visible spectroscopy. The presence of different reaction sites for NbO 7 and NbO 8 type systems, which are directly related to surface defects present in different states of crystallization, were fully characterized. The reactivity of different catalysts obtained from niobium(V) oxide was investigated, using the oxidation of methyl linoleate in the presence of hydrogen peroxide as probe reaction. The reaction was followed by GC-MS, as well as by 1 H and 13 C NMR spectrometry and the dominant product was 9-oxo-nonanoic acid methyl ester. A reaction mechanism related to an auto-oxidation process must be occurring, leading initially to the formation of hydroperoxides, which decompose rapidly via Hock-type rearrangement, leading to the formation of aldehydes.
