Diet and Genetics: Trp-ing Over Food Sensitivity

SummaryLaboratory-reared Caenorhabditis elegans eat Escherichia coli. A new study demonstrates a strong diet–gene interaction: worms with reduced nhr-114 activity are fertile when fed E. coli K-12 strains but are sterile on E. coli B. Surprisingly, tryptophan supplementation of E. coli B restores worm fertility
