  1. E. coli knockouts were identified as portrayed in Fig. 1a and functional groups were delineated as described in text and Fig. 1b. Brief descriptions were adapted from EcoCyc. Functional codes were abbreviated as follows: MET, metabolism; ITM, inorganic ion transport and metabolism; TRN, translation, posttranslational modification, protein turnover, chaperones; CEB, cell envelope biogenesis, outer membrane; DNA, DNA replication, recombination and repair; TRX, transcription; OTR, other; UNK, unknown.
  2. aThe mean percentage of dauer staged animals.
  3. bThe standard error of the mean in percent.
  4. cThe total number of individuals scored (includes all replicates).
  5. dThe p-value for a student’s two-tailed t-test comparing respective E. coli gene knockout strain to control strain.
