A Beetle Overcomes a Plant’s Defenses
Every cabbage plant conceals a bomb – a mustard oil bomb. For many insects, this makes the plant unpalatable. Franziska Beran from the Max Planck Institute for Chemical Ecology in Jena now knows, however, how insects can avert this danger: flea beetles, for example, outsmart the plants’ defensive weapon and even commandeer it for their own protection.
Bacteria are individuals that always operate in isolation? Not at all, says Christian Kost of the Max Planck Institute for Chemical Ecology in Jena. In fact, he thinks bacteria frequently can’t help but cooperate. His team is using cleverly devised experiments to test this hypothesis.
