Tradescantia pallida (Wandering jew)-a succulent perennial herb-was screened to be a potent chromium (Cr) accumulator. Its ability to grow under Cr stress was examined by studying biochemical changes and physiological response of the plant in presence of 5-20 mg L(-1) Cr(VI) concentration in hydroponic environment for up to ca. 90 days. Average Cr(VI) bioaccumulation in plant roots reached abou...

Plant assays play a great role in the biomonitoring of ecogenotoxicity and environmental pollution. Amongst them, specific locus systems provide a simple, relatively easily scored system for the detection of mutations in testing of chemicals and in situ. The screening is based on a phenotypic change caused by a mutation in a single locus. Numerous test systems have been developed, although some...
