Volatile Secondary Metabolites in Plant Stress Responses In 2007, researchers Casey Delphia, Mark Mescher, and Consuelo De Moraes (pictured at left) published a study on the production of different volatile chemicals by tobacco plants in response to predation by two types of insects: western flower thrips and tobacco budworms. Their results are shown in FIGURE 30.19. FIGURE 30.19 Volatile (airborne) compounds produced by tobacco plants in response to predation by different insects. Plants were untreated (C), attacked thrips (T), mechanically wounded (W), mechanically wounded and attacked by thrips (WT), attacked by budworms (HIV), or attacked by budworms and thrips (HVT). Values are in nanograms/day. Which treatment elicited the greatest production of volatiles?
Some analysts argue that in order to continue usingoil at the current rate, we must discover and add toglobal oil reserves the equivalent of two new SaudiArabian reserves every 7 years. Do you think this ispossible? If not, what effects might the failure to findsuch supplies have on your life and on the lives ofany children and grandchildren that you might eventually have?
Energy Efficiency of Biofuel Production Most of the plant material currently used for biofuel production consists of food cropsmainly corn, soybeans, and sugarcane. In 2006, David Tilman and his colleagues published the results of a 10-year study comparing the net energy output of various biofuels. The researchers grew a mixture of native perennial grasses without irrigation, fertilizer, pesticides, or herbicides, in sandy soil that was so depleted by intensive agriculture that it had been abandoned. They measured the usable energy in biofuels made from the grasses, and also from com and soy, then measured the energy it look to grow and produce biofuel from each kind of crop (Figure 6.1). FIGURE 6.1 Energy input and output of biofuels made from three different crops. One hectare is about 2.5 acres. About how much energy did ethanol produced from one hectare of corn yield? How much energy did it take to grow the corn to make that ethanol?
