Bottom Line: The first is cost- and labor-intensive and needs some developmental strategies for implication; on the contrary, the phytoremediation by halophyte is more suitable as it can be executed very easily without those problems.Several halophyte species including grasses, shrubs, and trees can remove the salt from different kinds of salt-affected problematic soils through salt excluding, excreting, or accumulating by their morphological, anatomical, physiological adaptation in their organelle level and cellular level.Exploiting halophytes for reducing salinity can be good sources for meeting the basic needs of people in salt-affected areas as well.

ABSTRACT
Salinity is one of the rising problems causing tremendous yield losses in many regions of the world especially in arid and semiarid regions. To maximize crop productivity, these areas should be brought under utilization where there are options for removing salinity or using the salt-tolerant crops. Use of salt-tolerant crops does not remove the salt and hence halophytes that have capacity to accumulate and exclude the salt can be an effective way. Methods for salt removal include agronomic practices or phytoremediation. The first is cost- and labor-intensive and needs some developmental strategies for implication; on the contrary, the phytoremediation by halophyte is more suitable as it can be executed very easily without those problems. Several halophyte species including grasses, shrubs, and trees can remove the salt from different kinds of salt-affected problematic soils through salt excluding, excreting, or accumulating by their morphological, anatomical, physiological adaptation in their organelle level and cellular level. Exploiting halophytes for reducing salinity can be good sources for meeting the basic needs of people in salt-affected areas as well. This review focuses on the special adaptive features of halophytic plants under saline condition and the possible ways to utilize these plants to remediate salinity.

Mentions: Based on ecological aspect, halophytes can be classified as (i) obligate, (ii) facultative, and (iii) habitat-indifferent halophytes [23]. Their growth pattern under saline condition is different (Figure 2). Obligate halophytes grow only in salty habitats. They show sufficient growth and development under high saline condition. Many plant species belonging to Chenopodiceae family fall in this category. Facultative halophytes are able to establish themselves on salty soils, but their optimum lies in a salt-free or at least low-salt condition. However, they can tolerate salt. Most Poaceae, Cyperaceae, and Brassicaceae species as well as a large number of dicotyledons like Aster tripolium, Glaux maritima, Plantago maritima, and so forth belong to this group. Plants that are indifferent toward their habitat are still able to cope with salty soils in nature. However, they usually grow on salt-free soils. They can compete with species that are sensitive towards salt and are on the other hand able to live on salty soils. Chenopodium glaucum, Myosurus minimus, and Potentilla anserina can grow in any habitat. In many species, such as Festuca rubra, Agrostis stolonifera, and Juncus bufonius, the populations living on salty soils and those on salt-free soils differ genetically [23]. However, all of these three kinds of halophytes perform better growth compared to glycophytes (Figure 2).
