“…These findings suggest that salt stress promotes a NO release from peroxisomes to the cytosol for the generation of ONOO - , which is involved in protein tyrosine nitration and thus provokes nitrosative stress. Furthermore, in cultures of arabidopsis and tobacco treated with NO donors and exposed to osmotic stress, it has been shown that the cell-wall area is one of the cell components richest in NO 2 -Tyr (Szuba et al, 2015) probably because the highest NO content is located in the cell-wall area. Finally a recent study of 2-day-old sunflower seedlings exposed to 120 mM NaCl has shown an increase in NO 2 -Tyr content in the cells of columella and the peripheral cells in roots (David et al, 2015).…”

In recent years, the study of nitric oxide (NO) in plant systems has attracted the attention of many researchers. A growing number of investigations have shown the significance of NO as a signal molecule or as a molecule involved in the response against (a)biotic processes. NO can be responsible of the post-translational modifications (NO-PTM) of target proteins by mechanisms such as the nitration of tyrosine residues. The study of protein tyrosine nitration during development and under biotic and adverse environmental conditions has increased in the last decade; nevertheless, there is also an endogenous nitration which seems to have regulatory functions. Moreover, the advance in proteome techniques has enabled the identification of new nitrated proteins, showing the high variability among plant organs, development stage and species. Finally, it may be important to discern between a widespread protein nitration because of greater RNS content, and the specific nitration of key targets which could affect cell-signaling processes. In view of the above point, we present a mini-review that offers an update about the endogenous protein tyrosine nitration, during plant development and under several abiotic stress conditions.

“…Peroxynitrite can react with cysteine thiolate anions, leading to the formation of cysteine sulfenic acid (Zeida et al, 2013). Furthermore, the formation of ONOO 2 results in the nitration of tyrosine residues; the existence of this reaction in the plant apoplast has only recently been documented (Szuba et al, 2015).…”

Bound by Fate: The Role of Reactive Oxygen Species in Receptor-Like Kinase Signaling

et al. 2017

In plants, receptor-like kinases (RLKs) and extracellular reactive oxygen species (ROS) contribute to the communication between the environment and the interior of the cell. Apoplastic ROS production is a frequent result of RLK signaling in a multitude of cellular processes; thus, by their nature, these two signaling components are inherently linked. However, it is as yet unclear how ROS signaling downstream of receptor activation is executed. In this review, we provide a broad view of the intricate connections between RLKs and ROS signaling and describe the regulatory events that control and coordinate extracellular ROS production. We propose that concurrent initiation of ROS-dependent and -independent signaling linked to RLKs might be a critical element in establishing cellular responses. Furthermore, we discuss the possible ROS sensing mechanisms in the context of the biochemical environment in the apoplast. We suggest that RLK-dependent modulation of apoplastic and intracellular conditions facilitates ROS perception and signaling. Based on data from plant and animal models, we argue that specific RLKs could be components of the ROS sensing machinery or ROS sensors. The importance of the crosstalk between RLK and ROS signaling is discussed in the context of stomatal immunity. Finally, we highlight challenges in the understanding of these signaling processes and provide perspectives for future research.

“…Accordingly, this nitro group can cause a gain of function, loss of function, or no effect in the targeted protein, the most usual one being the loss of function. The number of identified nitrated proteins in higher plants and how this modification affects its function has increased [18,[20][21][22][23][24]. Thus far, most of the identified proteins in plants that undergo this post-translational modification, usually mediated by peroxynitrite, have been found to provoke a loss of function.…”

Nitric oxide (NO) is a free radical and a component of the N-cycle. Nevertheless, NO is likewise endogenously produced inside plant cells where it participates in a myriad of physiological functions, as well as in the mechanism of response against abiotic and biotic stresses. At biochemical level, NO has a family of derived molecules designated as reactive nitrogen species (RNS) which finally can interact with different bio-macromolecules including proteins, lipids, and nucleic acids affecting their functions. The present review has the goal to provide a comprehensive and quick overview of the relevance of NO in higher plants, especially for those researchers who are not familiar in this research area in higher plants.
