“…Cys-oxidation processes play a vital role in redox homeostasis of plant cells. The initial oxidation of Cys with hydrogen peroxide leads to the formation of sulfenic acid (R-SOH), which can later be oxidized to sulfinic (R-SO 2 H) and sulfonic (R-SO 3 H) acids ( Valderrama et al., 2019 ). The oxidation of thiols to sulfinic acid is believed to be largely irreversible; however, these groups can be reduced by the ATP-dependent enzyme sulfiredoxin ( Rey et al., 2007 ).…”

“…Protein tyrosine nitration is a selective process consisting of the accession of a nitro group (-NO 2 ) to one of the two equivalent ortho -carbons in the aromatic ring of tyrosine residues to form 3-nitrotyrosine ( Valderrama et al., 2019 ). Tyrosine nitration has traditionally been considered an irreversible mechanism and a marker of nitrosative stress ( Corpas and Barroso, 2013 ).…”

“…However, the existence of tyrosine denitrase, which reduces 3-nitrotyrosine in mammalian cells, points to a role for tyrosine nitration in NO-mediated signaling in these cells. Yet, the specific denitrase protein has not been identified in plants and there is currently no information on these issues ( Valderrama et al., 2019 ).…”

However, this vast body of information is still poorly interpreted in the context of specific physiological processes and their role in plant adaptation to extreme temperatures.…”

Nitric oxide and hydrogen sulfide, as important signaling molecules (gasotransmitters), are involved in many functions of plant organism, including adaptation to stress factors of various natures. As redox-active molecules, NO and H2S are involved in redox regulation of functional activity of many proteins. They are also involved in maintaining cell redox homeostasis due to their ability to interact directly and indirectly (functionally) with ROS, thiols, and other molecules. The review considers the involvement of nitric oxide and hydrogen sulfide in plant responses to low and high temperatures. Particular attention is paid to the role of gasotransmitters interaction with other signaling mediators (in particular, with Ca2+ ions and ROS) in the formation of adaptive responses to extreme temperatures. Pathways of stress-induced enhancement of NO and H2S synthesis in plants are considered. Mechanisms of the NO and H2S effect on the activity of some proteins of the signaling system, as well as on the state of antioxidant and osmoprotective systems during adaptation to stress temperatures, were analyzed. Possibilities of practical use of nitric oxide and hydrogen sulfide donors as inductors of plant adaptive responses are discussed.

Mechanisms of Plasma-Seed Treatments as a Potential Seed Processing Technology

2021

View full text Add to dashboard Cite

Plasma treatments are currently being assessed as a seed processing technology for agricultural purposes where seeds are typically subjected to pre-sowing treatments to improve the likelihood of timely and uniform germination. The aim of this review is to summarize the hypotheses and present the evidence to date of how plasma treatments affect seeds, considering that there is difficulty in standardizing the methodology in this interdisciplinary field given the plethora of variables in the experimental setup of the plasma device and handling of biological samples. The ever increasing interest for plasma agriculture drives the need for a review dedicated to seeds, which is understandable to an interdisciplinary audience of biologists and plasma physicists. Seeds are the first step of the agricultural cycle and at this stage, the plant can be given the highest probability of establishment, despite environmental conditions, to exploit the genetic potential of the seed. Furthermore, seedlings seem to be too sensitive to the oxidation of plasma and therefore, seeds seem to be the ideal target. This review intentionally does not include seed disinfection and sterilization due to already existing reviews. Instead, a summary of the mechanisms of how plasma may be affecting the seed and its germination and developmental properties will be provided and discussed.
