“…Studies for the last 5 decades have suggested that the accumulation of proline in tissues confers some salinity tolerance in different plant species, including halophytes (Orcutt & Nilsen, 2000;Kavi Kishor et al, 2005). However, the plants under investigation, from different locations, exhibit different abilities to accumulate proline, and the content of proline shows wide variations (Youssef et al, 2003). Such variations may be dependent on various factors, such as the environmental factors of habitats and energy constraints.…”

“…In fact, the different views about the actual role of proline in the metabolism of plants under stress have generally been questioned (Yasseen & Abu-Al-Basal, 2008). However, glycine betaine accumulates in high concentrations in halophytes; according to many reports, it could be a main compatible osmolyte for the adaptability to saline environments (Rhodes & Hanson, 1993;Youssef et al, 2003).…”

“…Other physiological and biochemical activities can be carried out to lower the water and solute potentials of plant cells by accumulating organic and inorganic solutes. Moreover, osmoregulation is another activity conducted by plant tissues to maintain ion homeostasis inside plant cells and to regulate inorganic ions, including the toxic ones inside plant cells, through sequestration of Na + , Cl − , and possibly others, in the vacuoles, and the biosynthesis and accumulation of organic components, such as compatible solutes, proline, glycinebetaine, sugars (e.g., trehalose), and polyols at the cytoplasm [ 23 , 24 , 25 , 26 ]. The role of these compatible solutes to maintain the life of these plants in their natural habitats is well documented [ 26 , 27 , 28 , 29 , 30 ].…”

Many halophytes are considered to be salt hyperaccumulators, adopting ion extrusion and inclusion mechanisms. Such plants, with high aboveground biomass, may play crucial roles in saline habitats, including soil desalination and phytoremediation of polluted soils and waters. These plants cause significant changes in some of the soil’s physical and chemical properties; and have proven efficient in removing heavy metals and metabolizing organic compounds from oil and gas activities. Halophytes in Qatar, such as Halopeplis perfoliata, Salicornia europaea, Salsola soda, and Tetraena qatarensis, are shown here to play significant roles in the phytoremediation of polluted soils and waters. Microorganisms associated with these halophytes (such as endophytic bacteria) might boost these plants to remediate saline and polluted soils. A significant number of these bacteria, such as Bacillus spp. and Pseudomonas spp., are reported here to play important roles in many sectors of life. We explore the mechanisms adopted by the endophytic bacteria to promote and support these halophytes in the desalination of saline soils and phytoremediation of polluted soils. The possible roles played by endophytes in different parts of native plants are given to elucidate the mechanisms of cooperation between these native plants and the associated microorganisms.

This review considers the specific mechanisms of salinity adaptation in different salt-tolerant plant species. The differences among salt tolerance mechanisms are primarily associated with the organization of long-distance ion transport, including limitation of Na + and Cl À inflow to aboveground organs, their accumulation in vacuoles, or their excretion back to the environment (by salt glands on the leaf surface), maintaining a high K + /Na + ratio in the cytoplasm and additional synthesis of organic osmolytes. The review provides the current data on the role of proline, one of the most common organic osmolytes, in salinity adaptation in different plant species. Proline biosynthesis and catabolism regulation, as well as its multiple functions in plant cells, were described under normal and stress conditions. The changes in contents of proline and K + were analyzed in different types of halophytes, including salt-tolerant glycophytes, succulent euhalophytes, xerohalophytes, and recretohalophytes. Proline response to osmotic and ionic components of salinity, as well as its participation in fundamentally different adaptation mechanisms, was considered in different types of halophytes. The
