 The study investigates the transcriptomic response of a synitobacter bominini under ion-limiting conditions using a genomic microarray. Results show that 463 genes, including three-siderophore biosynthesis gene clusters, were highly upregulated. Ferric uptake regulator binding sites were identified in the promoter regions of many upregulated genes. Downregulation under ion limitation was less dramatic and involved various genes involved in motility. Motility assays confirmed these phenotypic changes. Comparative genomic analysis revealed important roles for mobile genetic elements in shaping siderophore mediated ion acquisition mechanisms between different synitobacter strains. Overall, the study showed that a bominini is adaptable to growth in an environment with limited ion availability. This article was offered by Paulson Ian T, Hasankal A, Yichkel Kampbat A and others.
