Scientists have created a genetically modified corn variety that can naturally defend itself against destructive rootworm pests by releasing a chemical signal that attracts nematodes—natural predators of the beetle larvae. When plants are under attack, they often emit volatile compounds that draw in beneficial insects to help fight off the invaders. However, over time, as farmers selected for faster-growing and more vigorous crops, and with increased pesticide use, many plants have lost this natural defense mechanism. To restore it, Ted Turlings and his team introduced a synthetic gene from oregano, specifically (E)-β-caryophyllene (EβC), which is known to attract nematodes. This genetic modification enabled the corn to regain its ability to repel pests.
In an experiment, the genetically modified maize was planted alongside regular corn that didn’t release the chemical. Beetle larvae were then introduced in large numbers. When nematodes were released into the experimental plots, the GM corn showed significantly less root damage and had 60% fewer adult beetles compared to the non-modified plants. The researchers believe that incorporating such defensive traits into commercial crops could enhance their natural resistance to pests. This approach might offer a sustainable alternative to chemical pesticides, helping scientists develop eco-friendly strategies for pest management in agriculture. By manipulating plant volatile emissions, farmers could reduce their reliance on harmful chemicals while protecting their crops more effectively.
