“…Species that have already been proposed as potential candidates for such purposes are Crithmum maritimum, Salicornia europea and Lepidium latifolium (Atia, Barhoumi, Mokded, Abdelly, & Smaoui, 2011;Ushakova, Kovaleva, Gribovskaya, Dolgushev, & Tikhomirova, 2005;Ventura & Sagi, 2013). Coastal and semi-arid areas, as well as areas where groundwater quality has been degraded due to irrational use of fertilizers could be the best candidates for cultivation of these species, since most of the conventional crops cannot be cultivated under such conditions or the yield losses affect severely trading profit.…”

“…plants (El-Fouly et al 2002). An alternative solution to the salinity problem is to select plant species capable of utilizing sufficiently high concentrations of NaCl, edible for humans, and featuring high productivity, with glasswort (Salicornia europaea L.) being one of the most promising candidates to be included in the human diet (Ushakova et al 2005). Employing glycinebetaine or proline provided cell membrane protection under salinity stress in onion (Allium cepa L.) bulbs (Mansour 1998).…”

Tzortzakis N.G., 2010. Potassium and calcium enrichment alleviate salinity-induced stress in hydroponically grown endives. Hort. Sci. (Prague), 37: 155-162.Salinity either of soil or of irrigation water causes disturbance in plant growth and nutrient balance and reduces crop yields. The effects of NaCl salinity and/or calcium or potassium level on the plant growth and severity of gray mold (Botrytis cinerea [De Bary] Whetzel) were investigated in endive (Cichorium endivia L., cv. Green Curled) grown with the nutrient film technique under greenhouse conditions during early spring. Plants were supplied with nutrient solutions containing 40 mmol/l of sodium chloride (NaCl) and/or 10 mmol/l potassium sulphate (K 2 SO 4 ). Additionally, plants treated with foliar spray of 15 mmol/l calcium nitrate [(CaNO 3 ) 2 ] or distilled water. Salinity or K-and Ca-enrichment mainly affected the upper part of endive plants and reduced leaf area. However, when salinity combined with either K-or Ca-enrichment, the negative impact of salinity on plant growth was reversed. Salinized and/or K-and Ca-enriched, plants did not differ in plant biomass, leaf/root ratio, leaf fresh weight, leaf number, and root length. Salinity did not have any impacts on photosynthetic rate, stomatal conductance, and intercellular CO 2 concentration. Indeed, photosynthetic rate and stomatal conductance increased with Ca foliar application and decreased with K while the opposite effects were observed for the intercellular CO 2 concentration. Total nutrient uptake was reduced 2-fold in salt-treated plants compared to controls. No symptoms of tip-burn or blackheart were recorded throughout the experimental study. Endive grown in the nutrient film technique had tolerance to NaCl salinity, and this method could be used to exploit saline water in soilless culture. These findings also suggest that a proper management of the salt concentration of the nutrient solution plus external elemental enrichment may provide an efficient tool to improve the quality of leafy vegetables with little effect on yield.

“…Thus, these plants must compartmentalize the toxic Na + in the vacuoles. Furthermore, S. europaea plants can accumulate up to 50% NaCl of dry weight in shoot (Lv et al, 2012;Ushakova et al, 2005). Therefore, we used S. salsa and S. europaea as excellent candidates for the design of improved novel proteins by DNA family shuffling, which promotes the range of salt tolerance, thereby yielding chimeras with higher salt tolerance than parents.…”

a b s t r a c tThe vacuolar Na + /H + antiporter plays an important role in maintaining ionic homeostasis and the osmotic balance of the cell with the environment by sequestering excessive cytoplasmic Na + into the vacuole. However, the relatively low Na + /H + exchange efficiency of the identified Na + /H + antiporter could limit its application in the molecular breeding of salt tolerant crops. In this study, DNA family shuffling was used to create chimeric Na + /H + antiporters with improved transport activity. Two homologous Na + /H + antiporters from halophytes Salicornia europaea (SeNHX1) and Suaeda salsa (SsNHX1) were shuffled to generate a diverse gene library. Using a high-throughput screening system of yeast complementation, a novel chimeric protein SseNHX1 carrying 12 crossover positions and 2 point mutations at amino acid level was selected. Expression of SseNHX1 in yeast mutant exhibited approximately 46% and 22% higher salt tolerance ability in yeast growth test than that of SsNHX1and SeNHX1, respectively. Measurements of the ion contents demonstrated that SseNHX1 protein in yeast cells accumulated more Na + and slightly more K + than the parental proteins did. Furthermore, this chimera also conferred increased tolerance to LiCl and a similar tolerance to hygromycin B compared with the parental proteins in yeast.
