“…Research on halophytes is increasing and focuses mainly on its biochemical properties and cultivation [ 1 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. The application of tissue culture refers only to a few species [ 13 , 14 , 15 , 16 , 17 , 18 ], but already yielded the optimization of cosmetic ingredients of high commercial value (CELTOSOME TM ) from sea fennel and sea holly ( Eryngium maritimum ) [ 19 ]. Such techniques are particularly useful for commercial crop species that exhibit limited sexual (seed) and vegetative propagation, which may hamper their large-scale cultivation [ 20 ], synthesis of metabolites with commercial interest, and for conservation programs of endangered/vulnerable species.…”

Halophytes are plants able to thrive in environments characterized by severe abiotic conditions, including high salinity and high light intensity, drought/flooding, and temperature fluctuations. Several species have ethnomedicinal uses, and some are currently explored as sources of food and cosmetic ingredients. Halophytes are considered important alternative cash crops to be used in sustainable saline production systems, due to their ability to grow in saline conditions where conventional glycophyte crops cannot, such as salt-affected soils and saline irrigation water. In vitro plant tissue culture (PTC) techniques have greatly contributed to industry and agriculture in the last century by exploiting the economic potential of several commercial crop plants. The application of PTC to selected halophyte species can thus contribute for developing innovative production systems and obtaining halophyte-based bioactive products. This work aimed to put together and review for the first time the most relevant information on the application of PTC to halophytes. Several protocols were established for the micropropagation of different species. Various explant types have been used as starting materials (e.g., basal shoots and nodes, cotyledons, epicotyls, inflorescence, internodal segments, leaves, roots, rhizomes, stems, shoot tips, or zygotic embryos), involving different micropropagation techniques (e.g., node culture, direct or indirect shoot neoformation, caulogenesis, somatic embryogenesis, rooting, acclimatization, germplasm conservation and cryopreservation, and callogenesis and cell suspension cultures). In vitro systems were also used to study physiological, biochemical, and molecular processes in halophytes, such as functional and salt-tolerance studies. Thus, the application of PTC to halophytes may be used to improve their controlled multiplication and the selection of desired traits for the in vitro production of plants enriched in nutritional and functional components, as well as for the study of their resistance to salt stress.
