The tolerance of Atriplex halimus L. to environmental stresses
Atriplex halimus L. (Amaranthaceae) (Mediterranean Saltbush) is a perennial, halophytic shrub that possesses the C4 photosynthetic anatomy and physiology. It grows under semi-arid and arid conditions (annual rainfall < 600 mm) from Macaronesia, through the Mediterranean basin countries and into western Asia, being particularly common on saline and degraded soils. Many studies have shed light on...
متن کاملGene expression and physiological analysis of Atriplex halimus (L.) under salt stress
Atriplex halimus (L.) is a xero-halophyte shrub adapted to extreme drought and salinity stresses. Ability of local A. halimus to tolerate salinity stress was investigated. Two-month-old A. halimus plants were exposed to salt stress (0, 150, 300 and 600 mM NaCl) in properly aerated liquid medium. Differential gene expression of stressed plants was investigated using real-time PCR analysis. Furth...
متن کاملVariability of Natural Populations of Atriplex Halimus L. in Morocco as Investigated by RAPD Markers
Atriplex halimus L. (Chenopodiaceae) is a monoecious C4 perennial shrub native to the Mediterranean Basin, used as fodder shrub for livestock and useful for rehabilitation of degraded rangelands. To assess the levels and patterns of genetic diversity of this species, 99 samples of 11 populations collected throughout the natural range in Morocco plus 9 samples obtained from one population origin...
متن کاملAtriplex atacamensis and Atriplex halimus resist As contamination in Pre-Andean soils (northern Chile).
The Pre-Andean area of Chile exhibits saline soils of volcanic origin naturally contaminated with arsenic (As), and we hypothesise that revegetation with resistant species may be a valid alternative for soil management in this area. Thus, the xerophytic and halophytic shrubs Atriplex halimus and Atriplex atacamensis were cultivated in containers for 90 days in Pre-Andean soil, As-soil, (111±19 ...
متن کاملVesiculated Hairs: A Mechanism for Salt Tolerance in Atriplex halimus L.
The concentration of salts in the vesiculated hairs of Atriplex halimus L. was measured and was remarkably higher than that of the leaf sap and xylem exudate. In spite of their unusually high salt content, these hairs when immersed seemed unable to absorb water, in apparent contradiction to the previously held hypothesis that vesiculated hairs make it possible for such plants to absorb water fr...
