Abstract. The evolution of salt tolerance is interesting for several reasons. First, since salt-tolerant plants (halophytes) employ several different mechanisms to deal with salt, the evolution of salt tolerance represents a fascinating case study in the evolution of a complex trait. Second, the diversity of mechanisms employed by halophytes, based on processes common to all plants, sheds light on the way that a plant's physiology can become adapted to deal with extreme conditions. Third, as the amount of salt-affected land increases around the globe, understanding the origins of the diversity of halophytes should provide a basis for the use of novel species in bioremediation and conservation. In this review we pose the question, how many times has salt tolerance evolved since the emergence of the land plants some 450-470 million years ago? We summarise the physiological mechanisms underlying salt-tolerance and provide an overview of the number and diversity of salt-tolerant terrestrial angiosperms (defined as plants that survive to complete their life cycle in at least 200 mM salt). We consider the evolution of halophytes using information from fossils and phylogenies. Finally, we discuss the potential for halophytes to contribute to agriculture and land management and ask why, when there are naturally occurring halophytes, it is proving to be difficult to breed salt-tolerant crops.

“…In order to counteract the detrimental effects of salinity on conventional crops, intensive research has been conducted, worldwide, to increase salt tolerance using genetic manipulation (Flowers, 2004), but the outcomes remain not significant so far (Läuchli and Grattan, 2007). An alternative approach is studied to utilize the natural salt-tolerance halophytes for sustainable crop production, particularly for economic interests (food, fodder and fuel) or ecological reasons (soil desalinization, phytoremidation, dune fixation, CO 2-sequestration) (Ashour et al, 1997;Leith and Mochtschenko, 2002;Reddy et al, 2008;Eid and Eisa, 2010;Koyro et al, 2011;Ladeiro, 2012;Hussin et al, 2013).…”

A prerequisite for sustainable saline agriculture of cash crop halophytes in salt affected areas implies exact knowledge of their limits of salinity resistance. Hence, the first part of this study was carried out in pot experiment under greenhouse conditions to evaluate growth and seed yield of C. quinoa Willd. cv. Hualhuas to varying water salinity levels (0, 100, 200, 300, 400 and 500 mM NaCl). The limit of salinity resistance was estimated at 200 mM NaCl (~20 dSm -1 ) based on seed yield production. Depending on the results obtained from pot experiment, field trials were conducted in saline soil location (ECe 17.9 dSm -1 ) and in non-saline soil location (ECe 1.9 dSm -1 ). Seed yield significantly decreased under saline soil by about 61.7% . Beside quantity, soil salinity led to reduce the percentage of moisture, total carbohydrate and total fat contents in seeds. Salinity did not significantly alter the protein content in quinoa seeds. Significant increases in the content of ash and fiber were detected in response to high soil salinity. The high er ash content in seeds under saline conditions was due to the increase of Na + as well as K + , P 3-and Fe ++ concentrations. By contrast, soil salinity led to significant decrease of Ca ++ and Zn ++ contents in seed. Energy dispersive X-ray microanalysis showed that most of Na + in the seeds produced at saline soil was mainly accumulated in the pericarp followed by embryo tissues, while, the interior reserving tissue (perisperm) exhibiting comparatively low concentration. Increasing most of essential minerals, especially Fe, in quino a seeds produced under high saline conditions given quinoa a distinctive value for human consumption. Quinoa can be grown and yielded successfully in salt-affected soils (ECe 17.9 dSm -1 ), where, most if not all of traditional crops cannot grow, although the yield was reduced however, the seed quality was not highly affected.

“…Differential response to salinity differs greatly among plant species depending on the capability to gather noxious ion (Flowers & Clomer 2008), levels of stress ) and environmental conditions (Ahmad et al 2016). Salt tolerant plants are well-known for their ability to tolerate the high stress of salinity (Reddy et al 2008), and are characterized by the presence of large air spaces and radiate chlorenchyma in leaf (Rad & Sonboli 2008).…”

Background: Soil salinity is a major menace to plants. Salt tolerant plants have developed different morphological, structural and physiological characteristics, which enable them to survive and reproduce under high salt concentrations. Hypothesis: It was hypothesized that differently adapted ecotypes of T. domingensis may have different structural and biochemical response to various levels of salt stress. Studied species/Data description: Six ecotypes of Typha domingensis Pers. were evaluated for anatomical and biochemical response and to find out the mechanism of adaptation under salt stress. Methods: All the ecotypes of Typha domingensis were acclimatized for a period of six months. Four levels of salinity viz. 0, 100, 200 and 300 mM NaCl were maintained. The plants were carefully collected from the medium to study various anatomical and biochemical characteristics. Results:The most promising anatomical modifications were; reduced leaf thickness in Sheikhupura, Gatwala and Treemu ecotype, increased cell vacuolar volume in Sahianwala and Knotti ecotype, larger metaxylem vessel in Sheikhupura and Gatwala ecotype, aerenchyma formation in all ecotypes and high sclerification in Sahianwala and Knotti ecotype. Accumulation of osmolytes mainly proline and glycinebetaine in Treemu, Sahianwala, Jahlar and Knotti ecotype under different levels of salt stress may be defense mechanism of T. domingensis to prevent severe loss in turgor. Conclusions:The results demonstrate that genetic potential of T. domingensis to grow under salt stress could be used for the purpose of phytoremediation and reclamation of soil salinity. Keywords: Phytoremediation; Foliar response; Organic osmolytes; Sclerification; Wetlands. ResumenAntecedentes: La salinidad del suelo puede llegar a ser una amenaza para las plantas. Sin embargo, las plantas tolerantes a la salinidad han desarrollado diferentes características morfológicas, estructurales y fisiológicas, las cuales les permiten sobrevivir y reproducirse en altas concentraciones de sal. Hipótesis: Los ecotipos adaptados de Typha dominguensis pueden tener diferentes respuestas tanto estructurales como bioquímicas a varias concentraciones de estrés salino. Especies estudiadas/Descripción de los datos: Seis ecotipos of Typha dominguensis Pers fueron evaluados en base a sus respuestas anatómicas y bioquímicas para determinar el mecanismo de adaptación bajo la influencia de estrés salino. Métodos: Todos los ecotipos de T. dominguensis fueron aclimatados por un período de seis meses. Y fueron mantenidos en cuatro niveles de salinidad: 0, 100, 200, 300 mM NaCl. Posteriormente, las plantas fueron colectadas cuidadosamente del medio para el análisis de las características bioquímicas y anatómicas. Resultados: Las más interesantes modificaciones anatómicas encontradas fueron: reducción del grosor de las hojas en los ecotipos pertenecientes a Sheikhupura, Gatwala and Treemu; incremento en el volumen de las vacuolas en la célula en los ecotipos correspondientes a Sahianwala and Knotti; increment...
