Did you know that plants can protect themselves from predators?

Writes Douglas Quenqua at the NY Times, “It has long been known that some plants can respond to sound. But why would a plant evolve the ability to hear? Now researchers are reporting that one reason may be to defend itself against predators.

“To see whether predator noises would affect plants, two University of Missouri researchers exposed one set of plants to a recording of caterpillars eating leaves, and kept another set of plants in silence. Later, when caterpillars fed on the plants, the set that had been exposed to the eating noises produced more of a caterpillar-repelling chemical. …

“Plants exposed to other vibrations, like the sound of wind or different insects, did not produce more of the chemical, suggesting they could tell the difference between predator noises and atmospheric ones. The researchers published their work in the journal Oecologia.” More here.

I have an idea. How about farmers, instead of using genetically modified seed to protect plants, just pump recordings of crunching predators into their fields so that the plants could protect themselves?

As they say where I work, “More research is needed.”
