In the original article, we did not notice the newest publication of Lovley group (Holmes et al. paper) when we submitted our manuscript, which previously demonstrated that the electrically conductive pili of Geobacter are recently evolved (Holmes et al., 2016). Here, the authors acknowledge the previous contributions of Lovley group and apologize for this oversight.
This error does not change the scientific conclusions of the article in any way.
Conflict of interest statement
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
