CEN1-lacO strain construction

Posted by deandawson on 05 May 2010 at 15:57 GMT

The plasmid pJN2 targeted 256 lacO repeats to CEN1 (coordinates 153583–154854). Correct integration was confirmed genetically.

The authors would like to acknowledge that original CEN1-lacO strain was constructed by Amit Bardhan (see ref. 17). CEN1-lacO strains used in this study were either provided by A. Bardhan (ABY194-Nd) or were derived by back cross with the original CEN-lacO strain or its descendents.

This note on CEN1::LacO strain construction was added after I expressed objection about the article.

Like with any in vivo genetic system, strain construction in yeast is a significant part of experiments. By elaborating the CEN1::LacO strain construction in the M&M without referring to the original article, and without specifying the source of the strain in the acknowledgement, this article seemed to originally suggest that construction of this strain was part of the work described in the article.

The Editor decided that these do not call for retrospective modification of the article since I was acknowledged for contributing “reagents” and since the article in which this strain was originally described was cited. The editor disregarded the fact that that citation was done in entirely different context. The editor also disregarded the fact that the same PLoS article described the source of a plasmid (PCYC1-lacI-GFP) in the same M & M section in addition to acknowledging the contributor.

Though I am not sure that the decision taken by the editor is the best possible one, particularly because the added note by the author would be visible only to exceptionally curious readers, I respect the editor’s decision.
