Arsenic Toxicity: An Arsenic-Hyperaccumulating Fern Uses a Bacterial-like Tolerance Mechanism
Abstract
The fern Pteris vittata can tolerate and hyperaccumulate levels of arsenic that would be toxic to other plants and animals. A recent study has shown that a bacterial-like tolerance mechanism has evolved in the fern, enabling it to tolerate and accumulate high concentrations of arsenic.
