SCIENCE, TECHNOLOGY, AND SOCIETY Hunger and malnutrition are urgent problems for many poor countries, yet plant biologists in wealthy nations have focused most of their research efforts on Arabidopsis thaliana. Some people have argued that if plant biologists are truly concerned about fighting world hunger, they should study cassava and plantain beeause these twe crops are staples for many of the world's poor. If you were an Arabidopsis researcher, how might you respond to this argument?

As you learned in this chapter, many prescription drugs are derived from natural plant products. Numerous other plant substances, including caffeine and nicotine, have effects in the human body, as well. There is also a wide array of plant products, in the form of pills, powders, or teas, marketed as herbal medicines. Some people prefer taking these “natural” products to pharmaceuticals. Others use herbal supplements to boost energy, promote weight loss, strengthen the immune system, relieve stress, and more. The U.S. Federal Drug Administration, which approves pharmaceuticals, is also responsible for regulating herbal remedies. What does the label “FDA-approved” on an herbal remedy mean? How does that compare to FDA approval of a drug? The FDA website http://www.fda.gov/ForConsumers/default.htm is a good place to start your research. (Note that the FDA classifies herbal remedies as dietary supplements.)

- TCE Uptake by Transgenic Plants Plants used for phytoremediation take up organic pollutants, then transport the chemicals to plant tissues, where they are stored or broken down. Researchers are now designing transgenic plants with enhanced ability to take up or break down toxins. In 2007, Sharon Doty and her colleagues published the results of their efforts to design plants for phytoremediation of soil and air containing organic solvents. The researchers used Agrobacterium tumefaciens (Section 15.7) to deliver a mammalian gene into poplar plants. The gene encodes cytochrome P450, an enzyme involved in the breakdown of a range of organic molecules, including solvents such as TCE. FIGURE 28.16 shows data from one test on the resulting transgenic plants. FIGURE 28.16 TCE uptake from air by transgenic poplar plants. Indvioual potted plants were kept in separate seated containers with an initial level of TCE (trichloroethytene) around 15.0C0 micrograms per cubic meter of air. Samples of the air m the containers were taken daily and measured for TCE content. Controls included a tree transgenic for a Ti plasmid with no cytochrome P450 in it (vector control), and a bare-root transgenic tree (one that was not planted in soil. 1.
