“…Plants under saline stress display a complex oxidative defense strategy of enzymatic antioxidants such as super oxide dismutase (SOD), glutathione reductase (GR), peroxidase (POX), catalase (CAT), ascorbate peroxidase (APX), dehydroascorbate reductase and monodehydroascorbate dehydrogenase [21][22][23] and non-enzymatic antioxidants included ascorbate, glutathione, phenolics, flavonoids and tocopherols [24][25][26][27][28] that counter the destructive effect of ROS by scavenging and transforming them into less damaging forms. Proline is an important osmolytes that gets accumulated to encountered salt stress [29][30][31] by decreasing the cytoplasmic osmotic potential and maintaining the turgor pressure, which ultimately facilitates the water absorption. Proline functions as redox potential controller, defends biomolecules and is said as single osmolyte which has been revealed to scavenge 1 O 2 (singlet oxygen) and other free radicals such as OH − [32].…”

Salinity is one of the most severe abiotic stresses for crop production. The present study investigates the salinityinduced modulation in growth indicators, morphology and movement of stomata, photosynthetic pigments, activity of carbonic anhydrase as well as nitrate reductase, and antioxidant systems in two varieties of chickpea (Pusa-BG5023, and Pusa-BGD72). On 20 th day of sowing, plants were treated with varying levels of NaCl (0, 50, 100, 150 and 200 mM) followed by sampling on 45 days of sowing. Recorded observations on both the varieties reveal that salt stress leads to a significant decline in growth, dry biomass, leaf area, photosynthetic pigments, protein content, stomatal behavior, cell viability, activity of nitrate reductase and carbonic anhydrase with the rise in the concentration of salt. However, quantitatively these changes were less in Pusa-BG5023 as compared to Pusa-BGD72. Furthermore, salinity-induced oxidative stress enhanced malondialdehyde content, superoxide radicals, foliar proline content, and the enzymatic activities of superoxide dismutase, catalase, and peroxidase. The variety Pusa-BGD72 was found more sensitive than Pusa-BG5023 to salt stress. Out of different graded concentrations (50, 100, 150 and 200 mM) of sodium chloride, 50 mM was least toxic, and 200 mM was most damaging. The differential behavior of these two varieties measured in terms of stomatal behavior, cell viability, photosynthetic pigments, and antioxidant defense system can be used as prospective indicators for selection of chickpea plants for salt tolerance and sensitivity.

“…On the contrary, Liu et al [13] explained that Na + stress (c. 7 mg g −1 Na FW) reduced the chlorophyll a and b contents, Fv/Fm, and NPQ values of Swiss chard under sodic-alkaline conditions. Mushtaq et al [25] confirmed that NaCl (150 mmol L −1 ) in soil reduced the content of photosynthetic pigments of Cicer arietinum, but little or no reduction was observed at low doses of salt (50 mmol L −1 ). However, inoculation with PGPR enhanced Fv/Fm, ΦPSII, chlorophyll, and carotenoid concentrations, stomatal conductance (Gs), and intercellular CO 2 concentration, with a consequent improvement of photosynthetic rate.…”

Inadequate fertilization or the indiscriminate use of water with high salt concentrations have led to salinization of agricultural soils. In this context, biofertilization with plant-growth-promoting rhizobacteria (PGPR) is an environmentally benign strategy to stimulate plant growth, even under salt stress. Thus, we studied the use of isolated PGPR consortia from halophytes to enhance Swiss chard growth under saline conditions. Growth, photosynthetic apparatus response, nutrient status, pigment concentrations, and secondary metabolites with antioxidant activity were determined in Swiss chard plants grown at 0 and 85 mmol L−1 NaCl. In general, inoculation of plants with PGPR has been shown to be an effective strategy to stimulate the growth of Swiss chard and improve its tolerance to salt stress. Inoculated plants watered with 85 mmol L−1 NaCl showed higher values of leaf dry weight than control plants. Furthermore, PGPR inoculation reduced electrolyte leakage and Na+ uptake and improved chlorophyll a fluorescence parameters, chlorophyll and carotenoid concentrations, stomatal conductance, and antioxidant capacity of Swiss chard. Finally, our findings highlight the potential of isolated PGPR from halophytes to counterbalance the deleterious effect of salinity and stimulate crop growth.

“…During plant infection with CMV, the host proteasome pathway is, at least partially, responsible for the degradation of CAT3 or CMV 2b that can interact directly with CAT3. During abiotic stress (e.g., drought) CAT3 activity is crucial [ 156 , 157 , 158 ] and CAT3 can mediate CPK8 functions in ABA-dependent stomatal regulation. Data suggest that the interaction of SOS2 with both NDPK2 and CAT2 and 3 reveals a point of cross talk between salt stress response and other signalling factors including H 2 O 2 .…”

In the environmental and organism context, oxidative stress is complex and unavoidable. Organisms simultaneously cope with a various combination of stress factors in natural conditions. For example, excess light stress is accompanied by UV stress, heat shock stress, and/or water stress. Reactive oxygen species (ROS) and antioxidant molecules, coordinated by electrical signalling (ES), are an integral part of the stress signalling network in cells and organisms. They together regulate gene expression to redirect energy to growth, acclimation, or defence, and thereby, determine cellular stress memory and stress crosstalk. In plants, both abiotic and biotic stress increase energy quenching, photorespiration, stomatal closure, and leaf temperature, while toning down photosynthesis and transpiration. Locally applied stress induces ES, ROS, retrograde signalling, cell death, and cellular light memory, then acclimation and defence responses in the local organs, whole plant, or even plant community (systemic acquired acclimation, systemic acquired resistance, network acquired acclimation). A simplified analogy can be found in animals where diseases vs. fitness and prolonged lifespan vs. faster aging, are dependent on mitochondrial ROS production and ES, and body temperature is regulated by sweating, temperature-dependent respiration, and gene regulation. In this review, we discuss the universal features of stress factors, ES, the cellular production of ROS molecules, ROS scavengers, hormones, and other regulators that coordinate life and death.
