FIG 1.

Gene expression of G. sulfurreducens under iron-deficient, iron-sufficient, and iron-excess conditions. (A) Heat map representing gene expression from all three iron conditions investigated. (B) Overlap between the gene expression profiles for the iron-deficient, iron-sufficient, and iron-excess conditions. (C) Fold change of expression among genes that exhibited significant differential expression across all three iron profiles. Purple represents the iron-deficient versus iron-excess condition, yellow represents the iron-sufficient versus iron-excess condition, and orange represents the iron-deficient versus iron-sufficient condition.
