“…Moreover, TaBAS1 enhances grain yield of wheat under salt stress, but has no adverse effect on the growth and yield under the control condition ( Figure 7 ), exhibiting its potential in the germplasm improvement of wheat without imposing the trade-offs between yield and tolerance. Moreover, 2-Cys Prxs have been proved to enhance the tolerance to cold, heat and drought ( Bhatt and Tripathi, 2011 ; Vogelsang and Dietz, 2022 ). Thus, the genes of 2-Cys Prxs and/or other components that directly modulating the level of H 2 O 2 (ROS) and other basic physiological bases of the adaption to abiotic stress could be used for improving broad-spectrum tolerance to abiotic stresses.…”

Efficient antioxidant enzymatic system contributes to salt tolerance of plants via avoiding ROS over-accumulation. Peroxiredoxins are crucial components of the reactive oxygen species (ROS) scavenging machinery in plant cells, but whether they offer salt tolerance with potential for germplasm improvement has not been well addressed in wheat. In this work, we confirmed the role of a wheat 2-Cys peroxiredoxin gene TaBAS1 that was identified through the proteomic analysis. TaBAS1 overexpression enhanced the salt tolerance of wheat at both germination and seedling stages. TaBAS1 overexpression enhanced the tolerance to oxidative stress, promoted the activities of ROS scavenging enzymes, and reduced ROS accumulation under salt stress. TaBAS1 overexpression promoted the activity of ROS production associated NADPH oxidase, and the inhibition of NADPH oxidase activity abolished the role of TaBAS1 in salt and oxidative tolerance. Moreover, the inhibition of NADPH-thioredoxin reductase C activity erased the performance of TaBAS1 in the tolerance to salt and oxidative stress. The ectopic expression of TaBAS1 in Arabidopsis exhibited the same performance, showing the conserved role of 2-Cys peroxiredoxins in salt tolerance in plants. TaBAS1 overexpression enhanced the grain yield of wheat under salt stress but not the control condition, not imposing the trade-offs between yield and tolerance. Thus, TaBAS1 could be used for molecular breeding of wheat with superior salt tolerance.

“…Alongside respiratory and photosynthetic electron transport and relevant enzyme activities, reactive oxygen species (ROS), derivatives of O 2 , originated as permanently formed byproducts of metabolism. To survive and grow under fluctuating environmental conditions, especially in the context of ongoing climate change and global warming, plants have evolved a complex system of molecular mechanisms and pathways of sensing, transmitting, and responding to optimal acclimatization [ 2 , 3 ]. The key components are ROS, in particular superoxide anions (O 2 •− ) and hydroxyl radicals ( • OH), which are free radicals containing an unpaired electron of varying reactivity, singlet oxygen ( 1 O 2 ), which is an excited non-radical derived from molecular oxygen by spin inversion, and hydrogen peroxide (H 2 O 2 ), originating from O 2 •− dismutation or directly from two electron transfer reactions.…”

Generation of ROS occurs in plastids, peroxisomes, endoplasmic reticulum (ER), mitochondria, apoplast, and cytosol [ 2 , 3 , 4 , 5 , 6 , 7 ].…”

Reactive oxygen species (ROS), and in particular H2O2, serve as essential second messengers at low concentrations. However, excessive ROS accumulation leads to severe and irreversible cell damage. Hence, control of ROS levels is needed, especially under non-optimal growth conditions caused by abiotic or biotic stresses, which at least initially stimulate ROS synthesis. A complex network of thiol-sensitive proteins is instrumental in realizing tight ROS control; this is called the redox regulatory network. It consists of sensors, input elements, transmitters, and targets. Recent evidence revealed that the interplay of the redox network and oxylipins–molecules derived from oxygenation of polyunsaturated fatty acids, especially under high ROS levels–plays a decisive role in coupling ROS generation and subsequent stress defense signaling pathways in plants. This review aims to provide a broad overview of the current knowledge on the interaction of distinct oxylipins generated enzymatically (12-OPDA, 4-HNE, phytoprostanes) or non-enzymatically (MDA, acrolein) and components of the redox network. Further, recent findings on the contribution of oxylipins to environmental acclimatization will be discussed using flooding, herbivory, and establishment of thermotolerance as prime examples of relevant biotic and abiotic stresses.
