Selenium hyperaccumulation makes the genus beneficial in plant-based prospecting, a strategy which utilizes plant populations to find fascinating mineral deposits. This can be accomplished merely by looking for the presence of ‘indicator plants’, consisting of certain astragalus species, or by taking samples of plant material and conducting chemical analyses for selenium.
