additional information	ipdC gene knock-out, strain SMIT568s10 which shows a significant (50%) decrease in the levels of indole-3-acetic acid, indole-3-acetaldehyde and tryptophol compared to the wild type strain SM. Reduction in the plant growth promoting response of strain SMIT568s10 is observed in terms of root length and lateral root proliferation as well as the total dry weight of the treated plants	Azospirillum brasilense
