Chemical constituents of Pteris cretica Linn. (Pteridaceae)
1. Subject and Source The group of fern from the genus Pteris (Pteridaceae) contains 250 cosmopolitan species (Mabberley, 1997). One species, P. cretica (Japanese name: ohbano-inomotoso) called Cretan brake fern is widely distributed in the temperate and warm area of Japan. Although some fern members of the family Pteridaceae are well known to contain carcinogenic C-14 illudane-type sesquiterpe...

متن کاملPhytoremediation of arsenic-contaminated groundwater by the arsenic hyperaccumulating fern Pteris vittata L.
Arsenic concentrations in a much larger fraction of U.S. groundwater sources will exceed the maximum contaminant limit when the new 10 microg L(-1) EPA standard for drinking water takes effect in 2006. Thus, it is important to develop remediation technologies that can meet this new standard. Phytoremediation of arsenic-contaminated groundwater is a relatively new idea. In this research, an arse...
متن کاملAn arsenate-activated glutaredoxin from the arsenic hyperaccumulator fern Pteris vittata L. regulates intracellular arsenite.
To elucidate the mechanisms of arsenic resistance in the arsenic hyperaccumulator fern Pteris vittata L., a cDNA for a glutaredoxin (Grx) Pv5-6 was isolated from a frond expression cDNA library based on the ability of the cDNA to increase arsenic resistance in Escherichia coli. The deduced amino acid sequence of Pv5-6 showed high homology with an Arabidopsis chloroplastic Grx and contained two ...
متن کاملMycorrhizae increase arsenic uptake by the hyperaccumulator Chinese brake fern (Pteris vittata L.).
Chinese brake fern (Pteris vittata L.) is a hyperaccumulator of arsenic (As) that grows naturally on soils in the southern United States. It is reasonable to expect that mycorrhizal symbiosis may be involved in As uptake by this fern. This is because arbuscular mycorrhizal (AM) fungi have a well-documented role in increasing plant phosphorus (P) uptake, P and As have similar chemical properties...
