Nitraria sibirica is a halophyte and belongs to the family Nitrariaceae. The chloroplast genome of Nitraria sibirica (159,466 bp) has a quadripartite structure, which consists of a large single-copy (87,914 bp) region, a small single-copy (18,316 bp) region, and a pair of inverted repeats (26,618 bp). Sequencing analyses indicate that the chloroplast genome contains 113 distinct genes, including 79 peptide-coding genes, 30 transfer RNA genes, and 4 ribosomal RNA genes. We also identified 105 perfect simple sequence repeats, 12 most divergent non-coding regions, and 6 most divergent coding regions when compared to the chloroplast genomes of the Sapindales plants...

A Gram-stain negative, oxidase- and catalase- positive, motile, aerobic, non-pigmented spirillum, designated CPA1T, was isolated from the surface-sterilized tissues of a halophyte, Halimione portulacoides, collected from a salt marsh in Aveiro, Portugal. The isolate was mesophilic, facultatively alkaliphilic and halophilic, and grew between 18 and 42.5 °C (optimum 30 °C), from pH 5.0 to 11.5 (optimum 7.0-7.5), from 0.5 to 5 % NaCl (w/v, optimum 2 %). Analysis of the 16S rRNA gene sequence showed that this strain belongs to the genus Saccharospirillum, as the highest sequence similarities were observed with Saccharospirillum impatiens EL-105T (96...

Lead (Pb) is a very toxic metal present in the environment, causing disturbances of several functions. Preventive or curative effects of halophytic plants against these disorders may be a promising and safe therapeutic strategy. Thus, this study was designed to evaluate in vivo immunomodulatory and antioxidant effects of Sarcocornia perennis extract (Sp) against lead toxicity in rats. Groups of six animals each were treated with plant extract (via food), 6 g/L lead acetate (via drinking water) or a combination of both...

Production of heteromorphic seeds is common in halophytes growing in arid environments with strong spatial and temporal heterogeneity. However, evidence for geographic variation (reflecting local adaptation) is almost nonexistent. Our primary aims were to compare the life history traits of two desert populations of this halophytic summer annual Suaeda corniculata subsp. mongolica and to investigate the phenotypic response of its plant and heteromorphic seeds to different levels of salt stress. Dimorphic seeds (F1) of the halophyte S...

Kristie S Wendelberger, Jennifer H Richards
Sea level rise (SLR) and land-use change are working together to change coastal communities around the world. Along Florida's coast, SLR and large-scale drying are increasing groundwater salinity, resulting in halophytic (salt-tolerant) species colonizing glycophytic (salt-intolerant) communities. We hypothesized that halophytes can contribute to increased soil salinity as they move into glycophyte communities, making soils more saline than SLR or drying alone. We tested our hypothesis with a replacement-series greenhouse experiment with halophyte/glycophyte ratios of 0:4, 1:3, 2:2, 3:1, 4:0, mimicking halophyte movement into glycophyte communities...

We evaluated the yields of Oryza sativa L. 'Nipponbare' rice lines expressing a gene encoding an A20/AN1 domain stress-associated protein, AlSAP, from the halophyte grass Aeluropus littoralis under the control of different promoters. Three independent field trials were conducted, with drought imposed at the reproductive stage. In all trials, the two transgenic lines, RN5 and RN6, consistently out-performed non-transgenic (NT) and wild-type (WT) controls, providing 50-90% increases in grain yield (GY). Enhancement of tillering and panicle fertility contributed to this improved GY under drought...

Mechanical wounding in plants, which are capable of generating defense responses possibly associated with nitro-oxidative stress, can be caused by (a)biotic factors such as rain, wind, herbivores and insects. Sea rocket (Cakile maritima L.), a halophyte plant belonging to the mustard family Brassicaceae, is commonly found on sandy coasts throughout Europe. Using 7-day-old Cakile maritima L. seedlings, mechanical wounding was induced in hypocotyls by pinching with a striped-tip forceps; after 3 h, several biochemical parameters were analyzed in both the damaged and unwounded organs (green cotyledons and roots)...

The aim of the present work was to analyze the impact of salinity on the plant response to Cd toxicity in the Mediterranean halophyte species Inula crithmoides. For this purpose, cuttings were cultivated hydroponically during 21d in the presence of 0, 25 or 50μM CdCl2 combined or not with 0, 100, 200 and 400mM NaCl. The obtained data demonstrated that, in the absence of Cd, NaCl strongly increased plant growth (the maximal dry weight being observed at 100mM) and enhanced the Na(+)/K(+) ratio in the shoot. Cd alone strongly affected plant growth in this halophyte...

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...

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...
