The authors apologize for an error in Materials and Methods in the above paper.

The final concentration of primers in a single real-time PCR should have been written as 0.5 μM (micro) not 1 nM (nano).

The full and correct sentence is given below.

Each 10 ml reaction contained 1× PCR buffer (Sigma–Aldrich Co.), 3 mM MgCl2, 0.2 mM dNTP, 0.5 μM forward and reverse primers, 1:50 dilution of ROX reference dye (Sigma–Aldrich Co.), 3:100 000 dilution of SYBR Green I (Sigma–Aldrich Co.), 0.05 U of JumpStart Taq polymerase (Sigma–Aldrich Co.) and template DNA.
