Abstract

“Over 200 papers, 3 reviews, a small book, and now a big book. What is it about this curious and unimportant character that has merited such attention?” This is the opening sentence from “The Essential Qualities”, an article discussing the “curious and unimportant character” of how plants adapt to elevated concentrations of trace metals in their environment (Bradshaw et al.,1990). Bradshaw and co-authors found the study of plant metal tolerance to be a valuable tool for the investigation of natural selection in plants (Bradshaw et al., 1990). However, in the proceeding ten years since the publication of this article, the “curious and unimportant character” of metal tolerance has attracted even more attention; and given rise to a new field of study termed phytoremediation. Because of the attractiveness of using plants to remove pollutant metals from the environment, numerous researchers have now begun to investigate phytoremediation, generating over 200 publications and millions of dollars of grant funding. However, at the center of all this new attention is still that “curious and unimportant character” highlighted by Bradshaw and coworkers. What do we know about its physiological, biochemical and molecular nature?
