Correction to: The ISME Journal advance online publication, 19 December 2014; doi: 10.1038/ismej.2014.242

Since the publication of this article, the publishers have identified that the sentence ‘We found that D-serine alone caused repression of the Type 3 Secretion System (T3SS) and induced the SOS response is not an acronym’ is incorrect and should be ‘We found that D-serine alone caused repression of the Type 3 Secretion System (T3SS) and induced the SOS’.

The publishers would like to apologise for any inconvenience caused.

This error has now been rectified, and the corrected article appears in this issue. The html and online pdf versions have also been rectified, and now carry the corrected paper.
