Background: The nematode Caenorhabditis elegans consumes bacteria as its sole food source.
Results: The bacterium Vibrio cholerae produces a quorum-sensing signal molecule called CAI-1, which C. elegans detects through the AWCON chemosensory neuron.
Conclusion: C. elegans uses bacterial-produced molecules as cues, and these molecules are also physiologically significant to bacteria.
Significance: The V. cholerae molecule CAI-1 enables cross-kingdom chemical interaction.
