Abstract: The present disclosure provides isolated and synthetic DNA and cDNA molecules encoding a phytase from the root of Pteris vittata (PV); root PV phytase proteins and peptides; root PV phytase antisense molecules, vectors, transgenic cells and plants containing root PV phytase nucleic acid molecules, isolated polypeptides, or antisense molecules; genetic markers for root PV phytase; and methods of using these nucleic acid or polypeptide molecules to improve phosphorus utilization from phytate by plants and animals.

Abstract: Processes and materials for phytoremediating water-containing sites which have been contaminated with pollutants such as arsenic, phosphorous, or other metals. Fern plants can be used to accumulate pollutants from contaminated water-containing sites having an aqueous solution, waste water, ground water, surface water, combinations thereof, and combinations of water-containing sites with soils and/or sediments. The fern plants remove pollutants from the water-containing sites, and can be harvested and readily disposed of, or can be treated to recover the pollutant.

Abstract: Processes, methods, materials and compositions for phytoremediating contaminated waters, which have been contaminated with pollutants such as arsenic, phosphorous, or other metals. Fern plants can be used to accumulate pollutants from contaminated water, including aqueous solution, waste water, ground water, surface water, combinations thereof. Pollutants and contaminants can be removed from the water, soil and wetland type environment via foliar application, excised leaflets, and/or through compositions of ground leaflets. The biomass can be harvested and readily disposed of, or can be treated to recover the pollutants and contaminants.

Abstract: Processes, methods, materials and compositions for phytoremediating contaminated waters, which have been contaminated with pollutants such as arsenic. Fern plants that include Pteris and non-Pteris fern plants can be used to accumulate pollutants from contaminated water, including aqueous solution, waste water, ground water, surface water, combinations thereof. Pollutants and contaminants can be removed from the water, soil and wetland type environment via phytoremediation through roots and fronds as well as by applying excised portions of plants such as leaflets (cut-off fronds). The biomass can be harvested and readily disposed of, or can be treated to recover the pollutants and contaminants.

Abstract: The invention provides processes and materials for phytoremediating materials which has been contaminated with arsenic, phosphorous, or other metals. In a preferred embodiment, the subject invention provides fern plants, which accumulate arsenic from contaminated materials. The fern plants efficiently remove arsenic from the materials. The fern plants can be harvested and readily disposed of, or can be treated to recover arsenic.
