When plants experience elevated concentrations of NaCl only a few species survive and set seeds. However, survival specialists – termed halophytes or, generally, extremophiles – can be found in essentially every plant family, seemingly identifying genes determining the halophytic lifestyle as a legacy of all plants. We have indicated the importance of transcription control leading to ‘copy numb...

The plasma membrane Na+/H+-antiporter salt overly sensitive1 (SOS1) from the halophytic Arabidopsis-relative Thellungiella halophila (ThSOS1) shows conserved sequence and domain structure with the orthologous genes from Arabidopsis thaliana and other plants. When expression of ThSOS1 was reduced by RNA interference (RNAi), pronounced characteristics of salt-sensitivity were observed. We were in...

Halimocnemis commixta is recorded as a new species for the flora of Iran from Pistacia vera woodland remnants in NE Iran. It grows on open salty soils with several typical halophytic plants. The new species record is illustrated and compared with the closely related species. It can be distinguished from H. gamocarpa by its clustered flowers and irregularly horned fruits and differs from H. pilo...

Three types of phenolic acids (caffeic, ferulic, and chlorogenic acid) were identified quantified in two halophytic plants (Salicornia bigelovii Salicornia sinus-persica). Analysis was performed using a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) system via the standard addition method. The matrix effect (ME), recovery efficiency (RE), process (PE) parameters ev...

Halophytes, gypsicoles and serpentinicoles are adapted to specialized edaphic conditions at arid semi-arid regions. These areas possess physical chemical stress factors for all plants. For these plants, one of the most important parameter that provides tolerance is proline accumulation. Proline a water-soluble amino acid generally accumulated under behave like an indicator adaptation plants aga...

Anthropogenic climate change is predicted to cause widespread biodiversity loss due to shifts in species' distributions, but these predictions rarely incorporate ecological associations such as zonation. Here, we predict the decline of a diverse assemblage of mid-latitude salt marsh plants, based on an ecosystem warming experiment. In New England salt marshes, a guild of halophytic forbs occupi...

This paper reports effects of salts on in vitro activity of phosphoenolpyruvate carboxylase and ribulose-1,5-diphosphate carboxylase, isolated from species differing in salt tolerance.Inhibition of phosphoenolpyruvate carboxylase by the inorganic salts KCl, NaCl, and Na(4)SO(4) depended on the source of the enzyme. Phosphoenolpyruvate carboxylase isolated from leaves of C(4) plants was extremel...

Continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. Using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. Thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...
