Inorganic Polyphosphate, Exopolyphosphatase, and Pho84-Like Transporters May Be Involved in Copper Resistance in Metallosphaera sedula DSM 5348T

Figure 5

Transcriptional levels of copA, copM, and copT genes at different points in the growth phase of M. sedula DSM 5348T cells grown in the presence of copper ions. (a) Diagram of the copTMA in M. sedula DSM 5348T. Relative gene expression was quantified by qRT-PCR. (b) Nonadapted cells exposed to 8 mM CuSO4. (c) Adapted cells exposed to 16 mM CuSO4. Error bars indicate standard deviations based on three different experimental values. Values with different letters differ significantly ().
