Halophytes are a category of plants that have adapted to survive and grow in soils with high salt concentrations. This environment is typically toxic to most conventional plants.

– Halophytes possess specific physiological adaptations (like salt excretion, succulence, or accumulating salts in specific tissues) to tolerate saline conditions.
– Saline soils are characterized by excessive amounts of soluble salts, mainly sodium chloride, sodium sulfate, magnesium chloride, and magnesium sulfate.

Examples of halophytes include mangroves, saltmarsh grasses, glassworts, and some species found in arid or semi-arid regions. Different halophyte species employ various mechanisms to cope with salinity stress, such as excluding salt uptake, excreting excess salt through salt glands, or diluting salt concentration by increasing water storage (succulence).
