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

Figure 6

Differential transcriptional expression of putative pho84-like genes in M. sedula DSM 5348T cells subjected to copper. (a) Nonadapted cells exposed to an 8 mM copper shift during the indicated times. (b) Nonadapted cells exposed to 8 mM CuSO4 during the indicated culture times. (c) Adapted cells exposed to 16 mM CuSO4. Values with different letters differ significantly ().
