Enhanced cell wall lignification is one of the major salinity tolerance strategies in the roots of halophytes. A deep insight into the exact root developmental system in halophytes may be of great importance for understanding plant salt tolerance mechanisms. In this work the developmental and anatomical changes in the roots of halophyte Aeluropus littoralis along with expression patterns of two genes encoding for cell wall laccase (LAC4) and peroxidase (PER64) were investigated. The plants were treated with 0, 300 and 600mM NaCl and root samples were collected 3, 6 and 9days after treatment (DAT)...

Plants have evolved different abilities to adapt to the ever-fluctuating environments for sessility. Calcium-dependent protein kinase (CDPK) is believed to play a pivotal role in abiotic stress signaling. So far, study on the specific substrates that CDPK recognized in response to adversity is limited. In the present study, we revealed a potential interaction between CDPK and a bHLH transcription factor under salt stress in Chenopodium glaucum. First, we identified a CgCDPK, which was up-regulated under salt and drought stress; then by Y2H screening, CgCDPK was detected to be involved in interaction with a bHLH TF (named as CgbHLH001), which also positively respond to salt and drought stress...

Metal contamination of estuaries is a severe environmental problem, for which phytoremediation is gaining momentum. In particular, the associations between halophytes-autochthonous rhizobacteria have proven useful for metal phytostabilization in salt marshes. In this work, three bacterial strains (gram-negative and gram-positive) were used for Spartina densiflora inoculation. All three bacteria, particularly Pantoea strains, promoted plant growth and mitigated metal stress on polluted sediments, as revealed from functionality of the photosynthetic apparatus (PSII) and maintenance of nutrient balance...

The plant-based-sea water culture medium is introduced to in vitro cultivation and in situ recovery of the microbiome of halophytes. The ice plant (Mesembryanthemum crystallinum) was used, in the form of juice and/or dehydrated plant powder packed in teabags, to supplement the natural sea water. The resulting culture medium enjoys the combinations of plant materials as rich source of nutrients and sea water exercising the required salt stress. As such without any supplements, the culture medium was sufficient and efficient to support very good in vitro growth of halotolerant bacteria...

Ionic stress is one of the most important components of salinity and is brought about by excess Na(+) accumulation, especially in the aerial parts of plants. Since Na(+) interferes with K(+) homeostasis, and especially given its involvement in numerous metabolic processes, maintaining a balanced cytosolic Na(+)/K(+) ratio has become a key salinity tolerance mechanism. Achieving this homeostatic balance requires the activity of Na(+) and K(+) transporters and/or channels. The mechanism of Na(+) and K(+) uptake and translocation in glycophytes and halophytes is essentially the same, but glycophytes are more susceptible to ionic stress than halophytes...

The effects of Cd on a halophyte of Doingying wild soybean (DY-03262) were studied by comparing it with a cultivated soybean (SN-11) via investigating photosynthetic activity, chlorophyll fluorescence and Cd concentrations in leaves after treatment with different concentrations of Cd (0, 50, and 100 μM) for 10 days. There were no significant differences in photosynthetic rate (PN), actual photochemical efficiency of PSII (ΦPSII), stomatal conductance (gs), and photochemical quenching (qP) between the both soybean species without Cd treatment, but they decreased greater in DY-03262 than that in SN-11 leaves after Cd treatment...

Salicornia and Sarcocornia are almost identical halophytes whose edible succulent shoots hold promise for commercial production in saline water. Enhanced sulfur nutrition may be beneficial to crops naturally grown on high sulfate. However, little is known about sulfate nutrition in halophytes. Here we show that Salicornia europaea (ecotype RN) exhibits a significant increase in biomass and organic-S accumulation in response to supplemental sulfate, while Sarcocornia fruticosa (ecotype VM) does not, instead exhibiting increased sulfate accumulation...

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...
