Expression of genes for iron acquisition is increased in tan strains.

Legend: * for multigene clusters, the range of expression change values is given.Partial list of genes showing significant expression changes in the M. xanthus tan variant and three tan mutants (12 datasets: four biological replicates with triplicate technical replicates) in DNA tiling array studies relative to the WT-Y variant (data not shown). Expression patterns consistent in four different tan M. xanthus strains (data for individual genes are provided in Table S1). MXAN ID and Description refers to annotation; both are derived from the M. xanthus genome [43]; fold change represents the increase (A) or decrease (B) in expression and is derived from coefficient value.
