Background and aims Proline and glycinebetaine are osmolytes playing a role in resistance to salt and water stress but their involvement in plant adaptation to heavy metals remain unclear. Methods Young plants of the halophyte Kosteletzkya pentacarpos were grown in nutrient solution in the presence of Cd (20 or 40 μM) or Zn (200 or 400 μM), or a combination of both heavy metals and in the presence...
Arsenic (As) is a highly toxic element accumulating in the environment as a result of anthropogenic activity. In Northern Chile it accumulates in salt areas and constitutes a major threat for human population. Atriplex atacamensis is a perennial halophyte shrub spontaneously growing in these contaminated areas. In order to determine the impact of salinity on As absorption and accumulation in A. atacamensis,...
Kosteletzkya virginica is a wetland halophyte that is a good candidate for rehabilitation of degraded salt marshes and production of oil as biodiesel. Salt marshes are frequently contaminated by heavy metals. The distribution of Zn in vegetative and reproductive organs of adult plants, and the NaCl influence on this distribution remain unknown and were thus explored in the present study...
