Unless indicated otherwise, the antibiotic resistance phenotypes are those expressed in E. coli. The antibiotic resistance phenotypes in parentheses are expressed in C. hutchinsonii . To generate the pYT3198 plasmid, two DNA fragments corresponding to approximately 2 kb of chu_3198 up- and downstream regions were amplified from C. hutchinsonii chromosomal DNA with the primers 3198upF/3198upR, and 3198downF/3198downR, respectively, and ligated into the pYT313 plasmid (Zhu et al., 2017 ).The authors apologize for this error and state that this 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.
