Correction

Following the publication of this article [1], the authors found that some of the primers listed in Table 1 are not correct. This mistake occurred during assembly of the primer table and the authors apologize for this error. This correction does not change the data included in the paper, their interpretation nor the conclusions drawn.

The corrected version of “Table S1: Sequences of primers used in the experiments” is included in this Correction article (Additional file 1).
