“…Moreover, Bezirğanoğlu (2017) reported that antioxidant enzyme activities (SOD, CAT and APX) exhibited an increasing trend in response to the increasing concentration of NaCl in callus of triticale genotypes. Antioxidant enzyme activity in many plant species has been reported to increase at the cellular level due to various stress factors (Libik et al, 2005;Niknam et al, 2011;Namjooyan et al, 2012;Munir and Aftab, 2013;Kuşvuran et al, 2016). On the other hand, Irani et al (2015) noted that water deficit significantly increased superoxide dismutase (SOD), ascorbate peroxidase (APX) and catalase (CAT) activities in whole-plant of sainfoin ecotypes.…”

“…The highest rate of increase in MDA content was noted in callus of "Altınova" ecotype which showed the lowest antioxidant enzyme activities among the ecotypes under drought stress (Table 1). Similarly, Kuşvuran et al (2016) reported that MDA content was high in callus tissue of melon cultivars that have low antioxidant enzyme activities under salt stress. Niknam et al, (2011) reported that there was a correlation between low lipid peroxidation (MDA content) and high antioxidant enzyme activities in callus of Acanthophyllum glandulosum and Acanthophyllum sordidum under salt stress.…”

“…Tissue culture techniques are used to determine the molecular basis of stress, resistance mechanisms to stress factors, physiological and biochemical events and changes in stress-induced molecules under stress conditions (Özcan et al, 2004). By using tissue culture, the physiological and biochemical events and changes that occur under stress conditions at cellular level has been previously reported in different genotypes or/and cultivars (Niknam et al, 2011;Namjooyan et al, 2012;Munir and Aftab, 2013;Kuşvuran et al, 2016;Bezirğanoğlu, 2017). However, there are limited reports on the effects of different stress factors on physio-biochemical changes of callus tissue in allied species of onobrychis such as alfalfa (legume) (Safarnejad, 2004;Ehsanpour and Fatahian, 2003).…”

Background: Drought is one of the important abiotic stress factors that restrict plant development. Sainfoin is known to be relatively tolerant of drought. However, there are limited reports on the effects of drought stress on antioxidant components of Onobrychis species and/or ecotypes. Methods: To determine drought stress effects on antioxidant components of 4 sainfoin ecotypes (“Koçaþ”, “Malya”, “Altýnova” and “Ulaþ”), callus tissue was grown on MS medium enriched with 200 g l-1 PEG-6000. Result: Callus of the sainfoin ecotypes, cultured on a medium having 200 g l-1 PEG-6000, showed significant increases in antioxidant enzyme activities (SOD, CAT, GR (except in “Ulaþ” ecotype) and APX). However, the PEG induced increase in the accumulation of MDA and proline in callus tissue of all sainfoin ecotypes. The findings of the present study show that in terms of the increasing rate of antioxidant components under drought stress, the “Koçaþ” ecotype seemed to be the best.

“…1). Using in vitro callus cultures, several researchers analyzed salt-stress-induced differential antioxidant activities in callus of different plant species such as Sugarcane (Patade et al 2012), Melon (Kusvuran et al 2016), and Triticale (Bezirganoglu 2017). The Gujosoya-2 and SL-295 genotypes were unable to maintain higher enzymatic antioxidant activities to cope with Na + stress.…”

“…In Medicago, Lotus, Faba bean, Barley, Chrysanthemum, Cucumber, and rice, it has been shown that controlled chloride transport and exclusion from shoot are well correlated (Sibole et al 2003;Teakle et al 2007;Tavakkoli et al 2010Tavakkoli et al , 2011Guan et al 2012;Huang et al 2015;Khare et al 2015). Most of the studies at cellular level have been carried out in the presence of NaCl salt (Rahnama et al 2003;Rahnama and Ebrahimzadeh 2004;Kusvuran et al 2016;Bezirganoglu 2017), but very meager information is available using individual Na + or Cl − salts. In vitro culture techniques offer a significant tool to evaluate genotypes for salt tolerance in less time and space at cellular level under uniform and controlled growth and treatment conditions (Nikam et al 2014;Piwowarczyk et al 2016;Bezirganoglu 2017;Boamponsem et al 2018).…”

Na+ and Cl− induce differential physiological, biochemical responses and metabolite modulations in vitro in contrasting salt-tolerant soybean genotypes

Chloride and sodium constitute as the major ions in most saline soils, contributing to salt-induced damage in plants. Research on salt tolerance has mostly concentrated on the sodium toxicity; however, chloride toxicity also needs to be considered to understand the physiological, biochemical, and metabolite changes under individual and additive salts. In this study, we investigated the effect of individual Na + and/or Cl − ions (equimolar 100 mM NaCl, Na + and Cl − salts) using in vitro cultures of four soybean genotypes with contrasting salt tolerance. In general, all the treatments significantly induced antioxidant enzymes activities such as catalase, ascorbate peroxidase, glutathione reductase, guaiacol peroxidase, and superoxide dismutase and osmolytes including proline, glycine betaine, and total soluble sugar (TSS). Both individual (Na + , Cl −) and additive (NaCl) stresses induced more pronounced activation of antioxidant enzyme machinery and osmolytes accumulation in the tolerant genotypes (MAUS-47 and Bragg). The sensitive genotypes (Gujosoya-2 and SL-295) showed higher accumulation of Na + and Cl − , while the tolerant genotypes were found to maintain a low Na + /K + and high Ca 2+ level in combination with enhanced antioxidant defense and osmotic adjustment. Gas chromatography-mass spectrometry (GC-MS)-based metabolomic profiling depicted the association of certain metabolites under individualistic and additive salt effects. The genotypespecific metabolic changes indicated probable involvement of azetidine, 2-furanmethanol, 1,4-dioxin, 3-fluorothiophene, decanoic acid and 2-propenoic acid methyl ester in salt-tolerance mechanism of soybean.

Soil salinity is a prevalent abiotic stress and affects around 20% of the irrigated land worldwide. Saline soil affects plant mineral nutrition and water uptake capacity. Plants adopt several strategies to combat salt stress such as synthesis of compatible solutes, control of ions uptake and transportation, production of enzymes and plant growth hormones, and ions accumulation or exclusion. Moreover, plants can also adapt to salt stress through a change in the whole metabolomics to overcome salt stress over a period of time. Metabolites, such as sugars, for instance, are important targets for mitigation of symptoms of salt stress. In spite of the scientific progress to date, still massive research work is to be done to investigate the actual physiological and molecular mechanism of metabolome and the underlying involved genes associated with salt resistance. In addition, expression, regulation, and function of genes and genetic pathways of metabolites, for example, proline, glycine betaine, abscisic acid, jasmonates, and flavonoids, that lead to the reestablishment of proper cellular ionic and osmotic homeostasis during salt stress, are not yet completely understood. This review presents an overview of past and current research on how plants, especially important crop plants, combat salt stress. Further, an attempt has been made to evaluate the gaps in current research and explore the role of genetic studies involved in metabolomics in order to enhance crop yield of salt‐affected soils in future.
