From: Transcriptome profiling of a Sinorhizobium meliloti fadD mutant reveals the role of rhizobactin 1021 biosynthesis and regulation genes in the control of swarming

Figure 6

Effect of pSymA, rhizobactin-related genes, and iron concentration on the motility of S. meliloti. A) Swarming test of wild type Rm2011 and a pSymA-cured derivative strain (SmA818). B) Swarming assay of mutants in the biosynthesis and transport of rhizobactin 1021 and in the rhizobial iron regulator rirA. C) Swimming test of Rm2011 and rhizobactin 1021-related mutants in Bromfield (0.3% agar). D) Swarming and E) swimming tests of Rm1021 and the rirA mutant in MM containing high iron concentration (220 μM). Photographs were taken either at 48 hours (A, B, and C) or 5 days (D and E) after inoculation and are representative of three replicates from at least three different experiments.
