What is Expression of Genes Involved in Heavy Metal Trafficking in Plants Exposed to Salinity Stress and Elevated Cd Concentrations about?
Many areas intended for crop production suffer from the concomitant occurrence of heavy metal pollution and elevated salinity; therefore, halophytes seem to represent a promising perspective for the bioremediation of contaminated soils. In this study, the influence of Cd treatment (0.01–10.0 mM) and salinity stress (0.4 M NaCl) on the expression of genes involved in heavy metal uptake (__irt2__–iron-regulated protein 2, __zip4__–zinc-induced protein 4), vacuolar sequestration (__abcc2__–ATP-binding cassette 2, __cax4__–cation exchanger 2 __pcs1__–phytochelatin synthase 1) and translocation into aerial organs (__hma4__–heavy metal ATPase 4) were analyzed in a soil-grown semi-halophyte __Mesembryanthemum crystallinum__. The upregulation of __irt2__ expression induced by salinity was additionally enhanced by Cd treatment. Such changes were not observed for __zip4__. Stressor-induced alterations in __abcc2__, __cax4__, __hma4__ and __pcs1__ expression were most pronounced in the root tissue, and the expression of __cax4__, __hma4__ and __pcs1__ was upregulated in response to salinity and Cd. However, the cumulative effect of both stressors, similar to the one described for __irt2__, wa
