Talks about:
Detoxifying symbiosis in pest insects
Pest insects lead to excessive agricultural and therefore economical losses on crops
worldwide (1). In recent years, research on insect-microbe symbioses has recognized
that microbial symbionts may play a role in protecting against toxic molecules that are
inherent to plant defenses, leading to a form of defensive symbiosis between the pest
insect and different types of microorganisms termed detoxifying symbiosis. We
investigate the detoxifying symbiosis of cabbage root flies which are challenged by
toxic isothiocyanates from their host plants (2,3). To achieve this, we use biochemical,
molecular and environmental techniques to generate a comprehensive understanding
of multispecies interactions.
