“…The amount of soil contaminated with heavy metals is increasing due to population explosion, urbanization, industrialization, and other anthropogenic activities [52,98]. Halophytes have shown a higher tolerance to heavy metals and a greater rate of absorption from the soil and, with increasing mobility, promote the transference and translocation of heavy metals from soil to root and among other plant components [99][100][101]. Zulfiqar et al [102] highlighted the effects and absorption level of cadmium (Cd) of C. album L. and C. murale L. While differential responses were observed, both species absorbed and sequestered Cd in their root and shoot and, hence, have been prescribed to be efficient phytoremediators of Cd in marginally contaminated soil with a minimal effect on the nutrient composition.…”

The global population is on the path of an increasing trajectory with a simultaneous decline in arable land resources through salinization and desertification that have resulted mainly from climate change and other anthropogenic activities. Rising temperatures will cause changes in the entire ecosystem, resulting in significant alterations in global climate paradigms and a threat to food security. This review focuses on how the highly resilient Chenopodium quinoa Willd. can sustainably mitigate some of the detrimental impacts, such as starvation, and support or provide ecosystem services. In comparison, compared with the traditional staple food crops, quinoa has remarkable tolerance to abiotic stresses and is highly nutritious, with a unique balance and higher amounts of nutrients, and can therefore be an important crop for food security and nutritional adequacy. This crop has the potential to ameliorate global challenges with respect to increase in global population, effects of climate change, desalinization, phytoremediation, satisfying nutrient deficiency, and alleviating poverty.

“…Using Mesembryanthemum crystallinum (halophyte) and Brassica juncea, the mechanism of nickel accumulation and tolerance has been studied (Amari et al, 2014). The halophyte Cakile maritima has been compared with Brassica juncea to understand cadmium accumulation and tolerance (Taamalli et al, 2014). In the same line, Sesuvium portulacastrum is a mangrove associate which is known for its high capacity to accumulate salt.…”

Salt stress, considered as one of the major environmental factors, decreases crop productivity worldwide and hence, investigations are being made to understand the cellular basis of salt tolerance in plants. In our earlier studies, maintenance of redox homeostasis and energetics were found as key determinants of salt tolerance in a halophyte Sesuvium portulacastrum (high salt accumulator). The redox homeostasis is defined as integrated ratio of different redox couples present inside the cell. In recent years, it has also been proposed as general stress response regulator in plants, bacteria as well as animals. In view of this, present study was performed to compare responses of redox state and energetics of S. portulacastrum with a glycophyte Brassica juncea (low salt accumulator). The data revealed activation of antioxidant defense in S. portulacastrum which either avoided or delayed the accumulation of different reactive oxygen species (ROS). In contrast, due to the lack of coordination , although the non-enzymatic antioxidants were increased, significant oxidative damage was seen in B. juncea. Further, the decreased NADPH oxidase activity suggested that basal redox signaling was also affected in B. juncea. In order to correlate these changes with chloroplastic and mitochondrial electron transport chain, NADP/NADPH and NAD/NADH ratios were measured. The NADP/NADPH ratio suggested that the process of photosynthesis was minimally affected in S. portulacastrum which might have contributed to its lower level of ROS under salt stress. The comparatively lower NAD/NADH and ATP/ADP ratios in S. portulacastrum as compared to B. juncea indicated the active and better utilization of energy generated to support different processes associated with salt tolerance. Thus, the findings suggest that coordinated regulation of antioxidant defense to avoid oxidative damage and proper utilization of energy are the key determinants of salt-tolerance in plants.

“…Hence it has been demonstrated that S. portulacastrum , for example, is able to accumulate Cd and Pb in the shoots without significant growth reduction ( Ghnaya et al, 2005 ; Zaier et al, 2010 ). These authors and others ( Amari et al, 2014 ; Taamalli et al, 2014 ) demonstrated that halophyte plants may tolerate heavy metals more efficiently than conventional glycophyte accumulator species such as Brassica juncea . This capacity may be controlled by several mechanisms of metal detoxification as the overproduction of phytochelatins ( Zaier et al, 2010 ) and chelation to organic acids ( Ghnaya et al, 2013 ).…”

“…Several recent works demonstrated that halophyte species are more adapted to cope with abiotic stress including heavy metals than salt sensitive ones ( Lefèvre et al, 2010 ; Zaier et al, 2010 ; Amari et al, 2014 ; Taamalli et al, 2014 ). Hence it has been demonstrated that S. portulacastrum , for example, is able to accumulate Cd and Pb in the shoots without significant growth reduction ( Ghnaya et al, 2005 ; Zaier et al, 2010 ).…”

The implication of organic acids in Cd and Ni translocation was studied in the halophyte species Sesuvium portulacastrum. Citric, fumaric, malic, and ascorbic acids were separated and quantified by HPLC technique in shoots, roots and xylem saps of plants grown on nutrient solutions added with 50 μM Cd, 100 μM Ni and the combination of 50 μM Cd + 100 μM Ni. Results showed that Cd had no significant impact on biomass production while Ni and the combination of both metals drastically affected plant development. Cadmium and Ni concentrations in tissues and xylem sap were higher in plants subjected to individual metal application than those subjected to the combined effect of Cd and Ni suggesting a possible competition between these metals for absorption. Both metals applied separately or in combination induced an increase in citrate concentration in shoots and xylem sap but a decrease of this concentration in the roots. However, a minor relationship was observed between metal application and fumaric, malic, and ascorbic acids. Both observations suggest the implication of citric acid in Cd, Ni translocation and shoot accumulation in S. portulacastrum. The relatively high accumulation of citric acid in xylem sap and shoot of S. portulacastrum could be involved in metal chelation and thus contributes to heavy metal tolerance in this species.
