The halophyte Mesembryanthemum crystallinum adapts to salt stress by salt uptake and switching from C3 photosynthesis to CAM (crassulacean acid metabolism). An important role in this process is played by transport proteins in the tonoplast of the central vacuole. In the present study we examine dynamic changes in the protein composition during salt-stress adaptation in microsomes from M. crysta...
All abiotic and biotic stresses induce or involve oxidative stress to some degree, and the plant ability to control oxidant levels is highly correlated with stress tolerance. Polyamines (PAs) have antioxidant properties and their induction in response to stress is well known. Mesembryanthemum crystallinum L., Thellungiella halophila Mey., Plantago major L. and Geum urbanum L. plants were grown ...
The effects of salinity on growth, water relations, glycinebetaine content, and ion accumulation in the perennial halophyte Atriplex griffithii var. stocksii were determined. The following questions were addressed: (1) What effect does salinity have on growth responses at different ages? (2) Is A. griffithii an ion accumulator? (3) Does A. griffithii accumulate glycinebetaine in response to sal...
Halophytes are plants that can naturally tolerate high concentrations of salt in the soil, and their tolerance to salt stress may occur through various evolutionary and molecular mechanisms. Eutrema salsugineum is a halophytic species in the Brassicaceae that can naturally tolerate multiple types of abiotic stresses that typically limit crop productivity, including extreme salinity and cold. It...
Seed heteromorphism provides plants with alternative strategies for survival in unfavourable environments. However, the response of descendants from heteromorphic seeds to stress has not been well documented. Suaeda aralocaspica is a typical annual halophyte, which produces heteromorphic seeds with disparate forms and different germination characteristics. To gain an understanding of the salt t...
desert and marginal lands of playas which are covered with halophyte shrubs, play a great role in supply of forage for livestock as winter rangelands. in this research, plant samples were collected from four palatable halophyte species for zandi sheep of qom desert rangelands including seidlitzia rosmarinus، halocnemum strobilaceum، alhagi camelorum and tamarix passerinoides in two phenological...
Salinity as one of the most important stresses disturbs favorable growth conditions of the plants leading to several metabolic disorders such as reactive oxygen species (ROS). Monodehydroascorbate reductase (MDHAR) with FAD (Flavin adenine dinucleotide) co-factor is one of the key enzymes in Glutathione-ascorbate pathway which reduces monodehydroascorbate (MDHA) radicals. In this study MDHAR ge...
Soil salinity and drought compromise water uptake and lead to osmotic adjustment in xero-halophyte plant species. These important environmental constraints may also have specific effects on plant physiology. Stress-induced accumulation of osmocompatible solutes was analysed in two Tunisian populations of the Mediteranean shrub Atriplex halimus L.-plants originating from a salt-affected coastal ...
Salt cress (Thellungiella halophila) is a small winter annual crucifer with a short life cycle. It has a small genome (about 2 x Arabidopsis) with high sequence identity (average 92%) with Arabidopsis, and can be genetically transformed by the simple floral dip procedure. It is capable of copious seed production. Salt cress is an extremophile native to harsh environments and can reproduce after...
