Evolution of selenium hyperaccumulation in Stanleya (Brassicaceae), The
Elemental hyperaccumulation is a fascinating trait found in at least 515 angiosperm species. Hyperaccumulation is the uptake of a metal/metalloid to concentrations 50-100x greater than surrounding vegetation. This equates to 0.01-1% dry weight (DW) depending on the element. Studies to date have identified 11 elements that are hyperaccumulated including arsenic, cadmium, cobalt, chromium, copper, lead, manganese, molybdenum, nickel, selenium (Se) and zinc. My research focuses on Se hyperaccumulation in the genus Stanleya (Brassicaceae). The threshold for Se hyperaccumulation is 1,000 mg Se kg-1 ...
