Salinity is among the most important abiotic stresses affecting crop production throughout the earth. Halophyte plants can sustain high salinity levels, therefore elucidating molecular mechanisms underlying their salinity resistance is beneficial for crop improvement. Aeluropus littoralis, a halophyte weed, is a great genetic resource for this purpose. Isolated expressed sequence taq (EST) sequences from A. littoralis under salinity stress, have given us the chance to find and analyze transcripts of genes involved in response to salinity...

High-fat and high-salt intakes are among the major risks of chronic diseases including obesity, nonalcoholic fatty liver disease (NAFLD), and nonalcoholic steatohepatitis (NASH). Salicornia is a halophytic plant known to exert antioxidant, antidiabetic, and hypolipidemic effects, and Salicornia-extracted salt (SS) has been used as a salt substitute. In this study, the effects of SS and purified salt (PS) on the aggravation of NAFLD/NASH were compared. C57BL/6J male mice (8-wk-old) were fed a high-fat diet (HFD) for 6 mo and divided into 3 dietary groups, which were additionally fed HFD, HFD + SS, and HFD + PS for 13 wk...

Salt stress is one of the most dramatic abiotic stresses that induce oxidative and osmotic stress simultaneously. Salt stress is known to be more effective in reducing growth and yield of glycophytes; however, halophytes are able to withstand salt stress. Nonetheless, variability exists among different halophytic plants species from different plant families. Chenopodium album belongs to Chenopodiacea family and is known as weed in many regions of world; however, it is a very interesting halophytic plant. Little research has conducted so far by considering C...

REVIEW
Avinash Mishra, Bhakti Tanna
Halophytes have demonstrated their capability to thrive under extremely saline conditions and thus considered as one of the best germplasm for saline agriculture. Salinity is a worldwide problem, and the salt-affected areas are increasing day-by-day because of scanty rainfall, poor irrigation system, salt ingression, water contamination, and other environmental factors. The salinity stress tolerance mechanism is a very complex phenomenon, and some pathways are coordinately linked for imparting salinity tolerance...

Recent findings encourage the use of halophytes in constructed wetlands for domestic wastewater treatment due to their special physiological characteristics as the ability to accumulate heavy metals and salts in their tissues makes them ideal candidates for constructed wetland vegetation. In this particular study, we investigated the application of halophytic plants in a horizontal flow constructed wetland for domestic wastewater treatment purposes. The pilot plant which was situated in Crete (Greece) was planted with a polyculture of halophytes (Tamarix parviflora, Juncus acutus, Sarcocornia perrenis, and Limoniastrum monopetalum)...

Epidermal bladder cells (EBC) have been postulated to assist halophytes in coping with saline environments. However, little direct supporting evidence is available. Here, Chenopodium quinoa plants were grown under saline conditions for five weeks. One day prior to salinity treatment, EBC from all leaves and petioles were gently removed using a soft cosmetic brush and physiological, ionic and metabolic changes in brushed and non-brushed leaves were compared. Gentle removal of EBC neither initiated wound metabolism nor affected the physiology and biochemistry of control-grown plants but did have a pronounced effect on salt-grown plants, resulting in a salt-sensitive phenotype...

Mercury (Hg) distribution in saltmarsh sediments and in three selected halophytes (Limonium narbonense, Sarcocornia fruticosa and Atriplex portulacoides) of a wetland system (Marano and Grado Lagoon, Italy) following a contamination gradient in sediments was investigated. The Hg uptake was evaluated at the root system level by calculating the enrichment factor (EF) and in the aboveground tissues by means of the translocation factor (TF). The related methylmercury (MeHg) concentrations in the halophytes were also investigated with regard to the location of the sites and their degree of contamination...

The main objective of this study was to test an innovative biomitigation approach, where polychaete-assisted (Hediste diversicolor) sand filters were combined with the production of Halimione portulacoides in aquaponics, to remediate an organic-rich effluent generated by a super intensive fish farm operating a land-based RAS (Recirculating aquaculture system). The set up included four different experimental combinations that were periodically monitored for 5months. After this period, polychaete-assisted sand filters reduced in 70% the percentage of OM and the average densities increased from ≈400ind...

The potential of a halophyte species-Acanthus ilicifolius L.-to phytostabilize zinc (Zn) grown under hydroponics culture conditions was critically evaluated in this study. The propagules after treating with ZnSO4 (4 mM) were analysed for the bioaccumulation pattern, translocation rate of Zn to the shoot, effects of Zn accumulation on organic solutes and the antioxidant defence system. It was found that most of the Zn absorbed by the plant was retained in the root (47%) and only a small portion was transported to stem (12%) and leaves (11%)...

Plants are the primary producers of food for human being. Their intracellular environment alternation is influenced by abiotic stress factors such as drought, heat and soil salinity. Aeluropus lagopoides is a strong halophyte that grows with ease under high saline muddy banks of creeks of Gujarat, India. To study the response of salinity on metabolite changes in Aeluropus, three treatments, i.e. control, salinity and recovery, were selected for both shoot and root tissue. The cytosolic metabolite state was analysed by molecular chemical derivatization gas chromatography mass profiling...

Zymoseptoria tritici, responsible for Septoria tritici blotch, is the most important pathogen of wheat. The control of this parasite relies mainly on synthetic fungicides, but their use is increasingly controversial and searching for alternative management strategies is encouraged. In this context, the biocontrol potential of crude methanolic extracts of eight extremophile plant species from Tunisia, including three xerophytes and five halophytes, against Z. tritici was assessed. Only the extract of Juncus maritimus rhizomes showed significant in vitro antifungal activity...

An obligate halophyte, Salicornia brachiata grows in salt marshes and is considered to be a potential resource of salt- and drought-responsive genes. It is important to develop an understanding of the mechanisms behind enhanced salt tolerance. To increase this understanding, a novel SbSRP gene was cloned, characterized, over-expressed, and functionally validated in the model plant Nicotiana tabacum. The genome of the halophyte S. brachiata contains two homologs of an intronless SbSRP gene of 1,262 bp in length that encodes for a stress-related protein...

Salt stress impacts multiple aspects of plant metabolism and physiology. For instance it inhibits photosynthesis through stomatal limitation, causes excessive accumulation of sodium and chloride in chloroplasts, and disturbs chloroplast potassium homeostasis. Most research on salt stress has focused primarily on cytosolic ion homeostasis with few studies of how salt stress affects chloroplast ion homeostasis. This review asks the question whether membrane-transport processes and ionic relations are differentially regulated between glycophyte and halophyte chloroplasts and whether this contributes to the superior salt tolerance of halophytes...

A Salicornia europaea L. in vitro cell transformation system was developed and further applied to SeNHX1 function investigation. The exploration of salt-tolerant genes from halophyte has seriously been limited by the lack of self-dependent transformation system. Here, an Agrobacterium tumefaciens-mediated in vitro cell transformation system of euhalophyte Salicornia europaea L. was developed. Calli derived from hypocotyl of S. europaea were co-cultured for 3 days with Agrobacterium at OD600 ranging from 1...

Utilization of rhizobacteria that have associated with plant roots in harsh environments could be a feasible strategy to deal with limits to agricultural production caused by soil salinity. Halophytes occur naturally in high-salt environments, and their roots may be associated with promising microbial candidates for promoting growth and salt tolerance in crops. This study aimed to isolate efficient halotolerant plant-growth-promoting rhizobacterial strains from halophytes and evaluate their activity and effects on sugar beet (Beta vulgaris L...

Puccinellia tenuiflora is a typical salt-excluding halophytic grass with excellent salt tolerance. Plasma membrane Na(+)/H(+) transporter SOS1, HKT-type protein and tonoplast Na(+)/H(+) antiporter NHX1 are key Na(+) transporters involved in plant salt tolerance. Based on our previous research, we had proposed a function model for these transporters in Na(+) homeostasis according to the expression of PtSOS1 and Na(+), K(+) levels in P. tenuiflora responding to salt stress. Here, we analyzed the expression patterns of PtSOS1, PtHKT1;5, and PtNHX1 in P...

It is assumed that salinity enhances the concentration of valuable metabolites in halophytes. The objective was to find a salt concentration and a point in time at which the yield for the valuable metabolites was maximal. Therefore, three different halophyte species were grown under different salinities and harvested over a period from shortly after stress induction up to three weeks. Various reaction patterns were found in the metabolite composition of the analyzed plant material. Halimione portulacoides showed a "short term response", indicated by an increase in all metabolites analyzed after a few hours, whereas Crithmum maritimum showed a "long term response" through accumulation of proline starting after days...
