Can plants be used to “strike it rich”? In this journal case study, students examine published research on the use of trees to search for, and to perhaps find, buried gold. The case focuses on Eucalyptus trees, the tallest of the flowering evergreen plants, and their capacity for uptake and deposit of gold in leaves. By working through the case, students will develop a better understanding of plant metal uptake, transport, and storage while analyzing and interpreting scientific data. They will examine how a metal in the soil is taken up by plant roots and translocated to the leaves; how trees might be used to prospect for gold; and how to design scientific experiments, evaluate hypotheses, and analyze data. Although specifically developed for a sophomore-level plant morphology course, the case is rich in material that can be easily adapted to other agriculture and plant science classes, especially those covering plant and soil nutrition (e.g., plant anatomy and development, plant physiology, or botany).
