Overproduction of indole-3-acetic acid in free-living rhizobia mimics physiological conditions required for nitrogen fixation inside root nodules

ABSTRACT: Background: The overproduction of the main auxin indole-3-acetic acid (IAA) in Sinorhizobium meliloti RD64 leads to beneficial effects both in free-living rhizobium and in host plant during symbiosis. These effects could be related to alteration in gene expression induced by IAA. Preliminary studies of these alterations induced in free-living cells have already started. In this work the transcriptional profiles of free-living S. meliloti wild type 1021 and RD64 strains obtained by RNA-seq analysis were used to better investigate this issue. Results: Transcriptome analysis by next-generation sequencing (RNA-seq) allowed the identification of the genes differentially expressed in RD64 cells, grown in a rich medium under aerobic conditions. Most of the up-regulated genes can be classified int
