  1. aThe genes studied are involved in phosphate solubilization (pyrroloquinoline quinone; pqqBCDEFG), 2,4-diacetylphloroglucinol synthesis (phlACBD), hydrogen cyanide synthesis (hcnABC), induced systemic resistance (acetoine and 2,3-butanediol; budAB and budC, respectively), NO synthesis (copper nitrite reductase; nirK), IAA synthesis (indole-3-pyruvate decarboxylase/phenylpyruvate decarboxylase; ipdC/ppdC), plant ethylene regulation (ACC deamination; acdS) and nitrogen fixation (nitrogenase; nifHDK).
  2. bMedian value (with the minimum and maximum values in parenthesis).
  3. cMinimum and maximum values when different.
