Whos the Pollinator? Massonia depressa is a low-growing succulent plant native to the desert of South Africa. The dull-colored flowers of this monocot develop at ground level, have tiny petals, emit a yeasty aroma, and produce a thick. jellylike nectar. These features led researchers to suspect that desert rodents such as gerbils pollinate this plant. To test their hypothesis, the researchers trapped rodents in areas where M. depressa grows and checked them for pollen. They also put some plants in wire cages that excluded mammals, but not insects, to see whether fruits and seeds would form in the absence of rodents. The results are shown in FIGURE 29.20. A The dull, petalless, ground-level flowers of Massonia depressa are accessible to rodents, who push their heads through the stamens to reach the nectar at the bottom of floral cups.

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?
