Cellular compartmentalization and accumulation of Aluminium in the halophyte of Arthrocnemum indicum

Abstract

It has been demonstrated that halophytes had the potential to accumulate heavy metals and therefore had the remediation potential of soils affected by metals. In this context, Arthrocnemum indicum was supplied with increased doses of Aluminium (Al) (200, 500, 800 µM) alone or added to NaCl (200 mM). Results demonstrated that Al was found mainly in the cell wall in the shoots and the roots.

The addition of the salt displaced the localization of Al in the roots, it was found bound to intercellular and proteiccomponents. These results suggest that the subcellular distribution of Al plays an important role in avoidance of metal toxicity.
