Abstract

Arsenic hyperaccumulation and tolerance in gametophytes and spores ofPteris vittata L. (brake fern) have been investigated. Gametophytes are able to grow normally in medium containing 50 to 200 or 300 μM arsenite and arsenate. In medium containing <300 μM arsenite and 500 μM arsenate, gametophytes do not almost grow. The highest arsenic concentrations in gametophytes are about 1,023 and 920 mg/kg-DW in medium containing 300 μM of arsenite and arsenate. The results suggest that gametophytes of the brake fern also has a great potential to be used for phytoremediating soils with low concentration of arsenic.
