To increase transparency, PeerJ operates a system of 'optional signed reviews and history'. This takes two forms: (1) peer reviewers are encouraged, but not required, to provide their names (if they do so, then their profile page records the articles they have reviewed), and (2) authors are given the option of reproducing their entire peer review history alongside their published article (in which case the complete peer review process is provided, including revisions, rebuttal letters and editor decision letters).
This submission was previously reviewed by the GCB 2016 conference and the authors supplied the prior reviews and their response to those reviews. I have evaluated the reviews and the revised materials - the response/edits to the previous reviews are considered sufficient to move forward with acceptance. Latex references in the latest version were missing, but were fine in the diff version, so these should be updated.
