TL;DR: The exploitation of genetic resources used in bioengineering strategies of plants is illuminating the function of sulfate transporters and key enzymes of the S assimilatory pathway in relation to Se accumulation and final metabolic fate, providing the basic framework by which to resolve questions relating to the essentiality of Se in plants.

TL;DR: Selenium-accumulating plants are a source of genetic material that can be used to alter selenium metabolism and tolerance to help develop food crops that have enhanced levels of anticarcinogenicSelenium compounds, as well as plants that are ideally suited for the phytoremediation of selenia-contaminated soils.

TL;DR: The results demonstrate the feasibility of developing transgenic plant-based production of Se-methylselenocysteine, as well as bioengineering selenite resistance in plants, and the engineering of Se tolerance in plants ideally suited for the phytoremediation of Se contaminated land.

TL;DR: It is shown that ACR3 localizes to the vacuolar membrane in gametophytes, indicating that it likely effluxes arsenite into the vacUole for sequestration and may explain arsenic tolerance in this unusual group of ferns while precluding the same trait in angiosperms.

TL;DR: The unusual active site of PvACR2 and the arsenate reductase activities of cell-free extracts correlate with the ability of P. vittata to hyperaccumulate arsenite, suggesting that PvacR2 may play an important role in this process.
