^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).
