The flooding of salt marshes with nutrient enriched seawater seems to favour dominant growth of nitrophytic halophytes such as the grass species . in ungrazed salt marshes. As a result the biodiversity of the salt marsh environment tends to decrease

It is discussed that in f

Affectation

Heavy metal resistance in higher plants: biochemical and genetic aspects, evidence that these compounds play an essential role in the tolerance mechanism. Other potential chelators such as organic acids could be of importance, but evidence for their role is lacking. Compartmentation of excess metals in subcellular bodies (vacuoles) or organs (leaves) seems an effective s

Physiological responses of higher plants to soil contamination with metals,surements at the subcellular level is emphasized. Enhancement of malondialdehyde content and ethane production in plants, treated with toxic amounts of Cu and Zn indicates that these metals affected membrane integrity by lipid peroxidation; the capacity of the enzyme lipoxygenase, involved in this p
