Correction to: Communications Biology https://doi.org/10.1038/s42003-019-0509-0, published online 11 July 2019.

In the original version of the article, the “Methods” section contained the following two incorrect statements:

  1. 1.

    “All reporter plasmids have a low-copy SC101 origin of replication with a kanamycin resistance cassette and a promoter transcriptionally controlling the gene for CFP.” This has been corrected to: “All reporter plasmids have a kanamycin resistance cassette and a promoter transcriptionally controlling the gene for CFP.”

  2. 2.

    “the vector was originally derived from the low-copy (SC101) vector pBbS5k.” This has been corrected to: “the vector was either SC101 origin pBbS5k or ColE1 origin pBbE5k (purA, inaA, hdeA, σ70, acrAB, and sodA reporters use pBbS5k; all others use pBbE5k).

The errors have been corrected in the HTML and PDF versions.
